Low Temperature Solution Depolymerization Of Pla
John Campanelli, May 2018
A novel depolymerization method using low-temperature, low-pressure alcoholysis of PLA in a ternary solution is outlined in this work. Depolymerization kinetics are studied for the PLA/methanol/chloroform system at 57°C. Large changes in molecular weight can be achieved at relatively mild conditions. A tin catalyst is found to increase the reaction rate significantly. The method is well-suited to industrial recycling processes and is consistent with the concept of a circular economy.
Mechanical Properties And Effects Of Microfibrillation Of 100 % Biomass Sisal-Pla Composite
Hiroyuki Nishimura, May 2018
The mechanical properties of sisal-PLA composites were measured with a parameter of length of sisal fiber, degree of microfibrillation, and mixing method of sisal fiber. The mechanical properties of sisal-PLA composites were also compared with those of wood flour, cellulose based on hardwood, and cellulose nanofiber composites. As a result, the higher tensile strength of the sisal-PLA composite was obtained by kneading PLA and microfibrillated sisal fiber wetted with organic solvent.
Synthesis Of High Hardness Polyester Resin For Powder Coatings
JUNSEOP IM, May 2018
Since powder coatings do not use VOCs, much research has been studied as eco-friendly paints. Among these powder coatings, hybrid type is widely used in home appliances and furniture. Therefore, it is very important to meet both aesthetic characteristics and mechanical properties such as gloss and hardness. However, it is difficult to maintain high gloss with high hardness because of the inorganic filler of powder coatings.
On The Use Of High-Throughput Electrospinning To Produce Optimized Packaging Films From Polyhydroxyalkanoates
Sergio Torres-Giner, May 2018
This study describes the preparation and characterization of electrospun films made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) produced by mixed bacterial cultures derived from a cheese whey (CW) industrial by-product. A mild thermal post-processing step carried out on the electrospun fibers mat, at a temperature below the biopolymer’s melting point, yielded a film with high transparency, enhanced crystallinity, and potentially sufficient mechanical and water barrier properties for sustainable packaging applications.
Nanocellulose As A Sizing Agent For Glass Fiber Towards An Enhanced Glass Fiber – Epoxy Interphase
Joyanta Goswami, May 2018
Glass fiber/nanocellulose/epoxy interfacial adhesion was explored to determine the optimum coating process and nanocellulose surface chemistry for glass fiber reinforced epoxy composites. The interfacial adhesion was assessed by photoelastic scattering under a microscope and interfacial shear stress (IFSS) determination by single fiber fragmentation test (SFFT). The effect of nanocellulose as glass fiber coating on the interphase was determined and prospects of nanocellulose sizing of glass fibers (GF) were discussed.
Optimizing Color: A Pigment- And Surface-Chemistry Perspective
Christopher Beier, May 2018
Effectively dispersing organic pigments within polymeric matrices is essential in maintaining consistent color and physical properties. Each and every pigment is chemically and physically unique, allowing for a myriad of potential molecular and macroscopic interactions to take place. This paper will discuss the physical (e.g. particle size, shape, distribution, morphology, surface area, porosity, etc.) and chemical (surface energy, polarizability, zeta potential, solubility, hydrophilicity, hydrophobicity, etc.) properties impacting a pigment’s interaction with its environment.

Fundamental Understanding Of Tribological Behavior Of Multiphase Polymeric Systems Using Fem Modeling
Mohammad Hossain, May 2018
Three-dimensional finite element method (FEM) modeling has been carried out to study the influence of dispersed particles on tribological behavior of multiphase polymeric systems. Specifically, effects of particle type and volume fraction on scratch behavior of multiphase polymeric systems have been investigated. The FEM findings correlate well with the experimentally observed scratch-induced damages. The results show that type and concentration of particles can drastically affect the stress and strain field development during the scratching process.
Effects Of Different Fillers On The Thermo-Mechanical Properties And Coefficient Of Linear Thermal Expansion Of Polypropylene Composites
Manjusri Misra, May 2018
We study and report on the effect of different fillers on the coefficient of linear thermal expansion (CLTE) of polypropylene (PP) by melt extrusion technique. We examine and review the effect of some fibers such as glass fiber and carbon fibers as well as traditional mineral filler like talc. Moreover, we study the effect of new biocarbon as an environmentally friendly filler on the CLTE of neat PP and compare with the previous samples. On the basis of these results, properties and potential applications of PP composites are discussed.

We give introduction to the theory and methods of simulation for the flow and warpage analysis. Further, two example cases are shown. One is a case where the flow during RTM process is studied. Another is the case where the warpage analysis is performed. The simulation results in this study are in good agreement with experimental results.
Developing Ultrasonic Processing Of Cnt Nanopaper/Solventless Epoxy Prepreg
Dan Zhang, May 2018
In this work, we propose an environmentally friendly innovative ultrasonic process to impregnate solventless epoxy into carbon nanotube (CNT) nanopaper (NP) (approximately 50 um thick) for fabricating prepreg nanocomposites. Both multi-wall carbon nanotube (MWNT) NP and single-wall carbon nanotube (SWNT) NP are used for prepreg fabrication. The prepregs show multi-functional performance in EMI shielding and sand erosion resistance. Process parameters including ultrasound time, amplitude level and pressure are studied for the fabrication process.
