Technical article briefs
Predicting water vapor transmission rates for extrusion-coated papers
Food product quality can be improved using a statistical approach to modeling barrier properties for packaging materials based on experimental data.
Improving properties of microparts by slow cooling
Significant structural and mechanical alterations can be caused by temperature changes associated with fabrication at very small dimensions, but they can also be mitigated through the use of low-thermally-conductive molds.
Lightweight nanocomposite hierarchical structures for blast mitigation
An energy-absorption approach to the design of protective panels produces polymeric materials that can withstand fire, smoke, and toxicity.
Using chemical blowing agents to make microcellular nanocomposites
A novel experimental setup for producing foams offers the advantages of simplicity and improved properties over conventional means of fabrication.
Enhancing cost-efficient micro-molding production with liquid crystal polymers
A liquid crystalline polymer is dispersed in a polyamide matrix in order to improve mold quality replication and reduce process costs.
Two-component injection molding: present and future perspectives
A technology that promises cost-effective and convergent manufacturing approaches for both macro and micro applications still has a way to go.
Sugar-powered fuel cells
High-intensity light pulses provide a means of making nanoscale modifications to electrode surfaces that is fast, inexpensive, and green.
Maleated polystyrene improves the barrier properties of nanocomposites
Polystyrene nanocomposites incorporating phosphonium-modified montmorillonite and a variety of polar compatibilizers have useful mechanical properties.
Determining the quality of a failed PVC pipe
A technique based on differential scanning calorimetry assesses the health of valuable pipes and fittings more accurately and quantitatively than current methods that use aggressive chemicals.
Counterpressure for microcellular injection molding
Applying different gas pressures at the melt stage improves parts production by controlling foaming and viscosity.
Evaluating dispersion in nanocomposites
Applying a combination of techniques to characterize polypropylene nanocomposites reveals critical aspects of the data analysis and sources of misinterpretation
Economics, sustainability, and the public perception of biopolymers
Biopolymers are a growing and useful sector of the plastics industry but are not a substitute for conventional polymers.
Structure and rheology correlation in polymer nanocomposites
Flow-reversal experiments and x-ray analysis show that the morphology of polymer nanocomposites evolves in time during and after processing.
Stiff, highly damping thermoplastic polyurethane nanolaminates
A new class of high-clay-content nanocomposites not only combines transparency, stiffness, and good damping properties but are also easier to test than their conventional counterparts.
Material characterization of novel bioplastics for food packaging
Composite polymers based on bioresins have attractive advantages, but require additional research for use in foodstuff industries.
Morphology for microcellular injection molding
Injection molding makes it possible to better control the structural alterations in microcellular foam, which can result in minimal material property changes for plastic parts.
Improving the properties of polylactic acid
The toughness, stiffness, and strength of eco-friendly polymers can be modified without significantly affecting optical clarity.
Manufacturing and troubleshooting polymer-based photovoltaics
A new kind of solar cell, made of doped polymers, promises efficiencies competitive with those of conventional silicon solar cells, and is cheaper to fabricate.
Tailoring vinyl acetate/acrylic acid copolymers through process optimization
Successful dynamic control of homogeneous copolymer composition is achieved while allowing for proper design of monomer feed-rate profiles and removal of process disturbances.
Revisiting Boltzmann kinetics in applied rheology
The dynamic viscosity of resins undergoing soft gelation shows a marked sigmoidal shape, suggesting that similarly shaped functions might be considered for model predictions.
