THE EFFECT OF FUNCTIONALIZATION ON POLYMER INTERCALATION AND PROPERTIES OF POLYSTYRENE/CLAY NANOCOMPOSITES
Musa R. Kamal , Jorge Uribe-Calderon, May 2009

Polystyrene nanocomposites were prepared using the following compatibilizers: a block copolymer of styrene maleic anhydride (SMA) and various functionalized polystyrenes terminated (on one or both ends) with various polar functional groups (e.g. OH, COOH, acrylate). Solvent mixing was used to promote intimate contact between the organoclay and compatibilizer. A phosphonium surfactant was used to modify the montmorillonite, in order to obtain a thermally stable organoclay. Generally, the best mechanical and barrier properties were obtained with the SMA copolymer.

SHEAR AND EXTENSIONAL RHEOLOGY OF CARBON NANOFIBER/POLYSTYRENE MELT COMPOSITES
Koki Miyazono , Christopher D. Kagarise , Monon Mahboob , Stephen E. Bechtel, May 2009

The rheological behavior and morphology of polystyrene / carbon nanofiber (PS/CNF) composites in their melt phase have been characterized through experimental measurements. Viscosity measurements of the PS/CNF composites in the linear viscoelastic regime show the ratio of the transient extensional viscosity to the transient shear viscosity to be greater than three, the Trouton ratio. This behavior is believed to be due to differences in the flow induced orientation of the CNFs in shear and extensional flow. The orientation development of the CNFs were analyzed by TEM and optical microscope and considered for the relationship to rheological behavior.

EFFECT OF MOLDING PARAMETERS AND ORIENTATION ON THE PROPERTIES AND SKIN-CORE STRUCTURE OF POLYPROPYLENE PLAQUES
S. Villarroel , R.A. Morales , M. Sánchez-Soto, May 2009

The major objective of this work was the study of the injection molding process conditions (holding/packing pressure, injection temperature, injection speed) and the geometry of the mold over the mechanical properties, morphology, orientation and core-skin structure of polypropylene (PP) plaques. Tensile test type IV specimens were cut in MD and TD directions of injected plaques (100 x 100 x 1 mm) with a 1 mmthick fan gate. Two different behaviors were clearly observed: there were groups with strain at break lower than 25% while others exhibit strains at break higher than 700%.

POLYPHENYLENE ETHER MACROMONOMERS. II. PROPERTY ENHANCEMENTS IN CYANATE ESTER RESINS
Edward N. Peters , Scott M. Fisher , Nancy Jestel , Mark Pietrafesa , Hua Guo, May 2009

Unique low molecular weight polyphenylene ether telechelic copolymers were designed specifically foruse in a variety of thermosetting resins. These macromonomers have high solubility in common solvents and monomers and tailored functionality, which can react with cyanate esters. The incorporation of these copolymers in cyanate ester resins results in single-phase thermoset material with enhanced performance. Noticeably, toughness increases and moisture absorption decreases with increasing PPE content. Dielectric properties are very low. These cyanate ester/PPE materials show a performance profile well suited for electronics and composites.

INVESTIGATION INTO THE EFFECT OF EXTRUSION AND THERMOFORMING PARAMETERS ON THE PROPERTIES OF POLYPROPYLENE CONTAINERS
E. McConville , P.J. Martin , E.M.A. Harkin-Jones, May 2009

Extruded polypropylene (PP) sheet is widely used in the production of thin gauge containers for the food and beverage industry using the thermoforming process. In industry there is not a clear understanding of the relationship between the effect of varying extrusion and thermoforming parameters and the resultant changes in end product properties. This paper investigates the effect of parameters such as chill roll temperature and haul off speed during extrusion, and plug speed and sheet temperature during thermoforming on end product properties such as wall thickness distribution, weight and compressive strength. Test results show several parameters have a large effect on end product properties, with greatest variations between different material grades.

STRATEGIES FOR THE REPLACEMENT OF LEAD- AND CHROME-BASED PIGMENTS IN SYTHETIC TURF
Tad Finnegan, May 2009

Lead- and chrome-based pigments have been used in synthetic turf due to their performance properties and low cost in use. Environmental and regulatory concerns about these heavy metal-based pigments are leading the synthetic turf industry to voluntarily adopt guidelines that will effectively eliminate their use by 2010. Currently, no drop in" replacements exist for lead-based pigments. The variety of polymers used in synthetic turf further complicates finding solutions. Reformulation strategies using organic and inorganic colorants along with light stabilization systems are presented for several polymers."

THE MAP IS NOT THE TERRITORY: AN EXPLORATION OF RADICAL INNOVATION
Bonnie J. Bachman, May 2009

Radical Innovation (RI) has been defined by the researchers who published the first study on RI in 1994 as 'a product, process, or service with either unprecedented performance features or familiar features that offer potential for significant improvements in performance or cost.' If these conditions hold, dramatic changes in products, processes or services may change existing markets and/or industries and be responsible for creating new ones. This can occur through several routes including technological discoveries, greatly improved services and processes, and novel business models. Traditional product development efforts result in incremental and platform innovations, however, it takes being comfortable with high uncertainty, seeing and thinking differently particularly about technology and business models, and an element of passion to create Radical or Breakthrough Innovations. This type of innovation is surrounded by high uncertainty and requires different maps, such as learning plans, discovery driven thinking, nontraditional success metrics, and portfolio management rather than project management and traditional gating processes and tools. RI territory will be explored through two case studies involving products and businesses with a focus on plastics and polymers.

LOOKING BEYOND THE INVENTION OF NEW TECHNOLOGY OR A NEW PRODUCT
Jack T. Peregrim, May 2009

In hundreds of projects across many different companies; we have worked with teams who have invented a new technology or product and then wanted to take a 'cookie cutter' approach to capturing value from the invention. Because each invention, by its definition as an invention, is unique and differentiating, we need to at least consider different options. Pre and post invention and pre and post commercialization. Two examples of alternative ways to capture value from invention are exemplified but there are dozens of additional ways to be innovative beyond the cases highlighted. The lesson is that neither client would have followed any other path than to invent its new product and then sell it to traditional customers with the approach they have already taken. The 'tried and true' process.

PLASTIC MICROFLUIDICS: TRANSFORMATIVE TECHNOLOGY FOR TOMORROW
Patrick Mather , Sadhan Jana , Prithu Mukhopadhyay, May 2009

Abstract #1: Design, Fabrication and Applications of Polymer Microfluidic Biochips Microtechnology is initiated from the electronics industry. In recent years, it has been extended to micro-electro-mechanic system (MEMS) for producing miniature devices based on silicon and semi-conductor materials. However, the use of these hard materials alone is inappropriate for many biomedical devices. Soft polymeric materials possess many attractive properties such as high toughness and recyclability. Some possess excellent biocompatibility, are biodegradable, and can provide various biofunctionalities. I will first give a brief overview of major activities in our center on micro/nanomanufacturing of polymeric materials and microfluidics. An enzyme immunoassay chip will be discussed as an example for a low-cost and mass-producible lab-on-a-chip platform for molecular and biological analyses. The platform is a microfluidic CD for Enzyme-Linked Immunosorbent Assays (ELISA) that reduces cost, accelerates results, and improves reliability of analyses for food borne contaminants, cancer diagnoses and environmental contamination. The presentation will cover (1) optimization and integration of the critical microfluidic and biochip packaging methods developed for CD-ELISA applications, (2) development of manufacturing and detection protocols for the CD-ELISA chips, and (3) evaluation of the performance of CD-ELISA's by validating testing for food borne pathogens and cancer cytokines.?ÿ ?ÿ Abstract #2: Bio-applications of Microfluidics: A flexible microfluidic device to characterize bacterial biofilms We characterize the viscoelasticity of bacterial biofilms by means of a flexible microfluidic device. The biofilms are comprised of Staphylococcus epidermidis and Klebsiella pneumoniae.?ÿ The presence of implanted foreign bodies such as central venous catheters is a key risk factor for infection by bacteria of this kind.?ÿ Because of the sensitivity of biofilm properties to environme

MICROFLUIDICS FOR RAPID PERSONALIZED DIAGNOSTICS – ARE THERMOPLASTICS THE ULTIMATE SOLUTION?
E. Roy , M. Geissler , T. Veres , M.M. Dumoulin, May 2009

The development of disposable microfluidic devices for rapid point-of-care applications has become central to progress in medical diagnostics and a variety of other fields. Microfluidics is the technology of engineering flow at the micrometer scale, making it possible to perform multiple operations on a single chip. The use of these systems is attractive because they promote reduced sample consumption and analysis time without being restricted to standard laboratory settings. To this end, lab-on-a-chip (LOC) systems have mostly been shown to function in conceptual ways, yet their commercialization and widespread use has been hindered by a number of challenges, which include materials and low-cost fabrication technologies as primary concerns.

NEW STRUCTURAL POLYMER FOR METAL REPLACEMENT APPLICATIONS
Dr. Mike Zimmerman , Chris Lee , Dan Ward , Eric Paszkowski , Rick Boisjoly , Jim Elliott , Michael McGee, May 2009

Recent developments based on a novel thermoplastic Liquid Crystal Polymer (LCP) molecule and compound formulation have led to a new material which can exceed the properties of traditional plastics and demonstrate metal-like properties for structural applications. Developed with a very high modulus (>20,000MPa), tensile strength (125 MPa) and an extremely high strength-to-weight ratio, this material is isotropic and has a tailored Coefficient of Thermal Expansion (CTE) of 17x10-6/?øC matching aluminum and steel. The material has balanced dimensional stability and ultra-low shrinkage (0.05%) with high temperature stability up to 420?øC. These metal-like properties have been identified as a metal replacement material for structural applications in a variety of applications and markets.

Evaluation of Fusible PVCTM Pipe as a Sustainable Infrastructure Solution
Bob Walker, May 2009

As issues regarding environmental protection and sustainability have moved higher on public and political agendas, the demand for PVC pipe has also risen. The current North American market for PVC pipes and fittings exceeds six billion pounds annually and PVC pipes account for the majority of new water and wastewater pipelines. Indeed, the PVC pipe industry owes much of its success to environmentalists and the environmental movement. More importantly, our environment has benefited immensely as a result of the widespread use of PVC pipe.
