Technical article briefs
Plasma helps polyethylene weather the sandstorm
Treating polyethylene with an atmospheric plasma alters its surface properties and may lead to improved resistance to abrasion by sand winds.
Injection molding without the drying
Using a gas counter to raise the pressure during injection molding of plastics prevents blisters forming by suppressing evaporation of water and cuts costly drying steps from the manufacturing process.
Supercritical carbon dioxide as an effective tool for composite preparation
Microporous chitosan and chitosan/nanosized hydroxyapatite particle composite scaffolds can be successfully prepared using a supercritical carbon dioxide-assisted process for tissue engineering applications.
Optimum dispersion of single-walled nanotubes in epoxy resins
Mechanical and chemical treatment of carbon nanotubes can improve their ability to disperse uniformly in epoxy resins and, as a result, alter the rheological behavior of the composite materials.
Starch-filled polymer composites
A new method produces robust, degradable polymer composites at room temperature from starch and alkyl cyanoacrylate.
Predicting layer rearrangement in extrusion
Numerically simulating and predicting viscoelastic materials' secondary flow behaviors could help optimize extruder designs and process parameters.
Polyamide 6-wheat straw composites: degradation kinetics
The degradation kinetics of wheat straw fillers and their polyamide 6 composites, an environmentally friendly alternative to polyamide 6, are analyzed for use in the manufacture of industrial parts.
Towards improved impact performance of injection molded plastic parts
We explored the mechanical response of complex polypropylene-based systems during an instrumented falling weight impact test to evaluate the effect of various processing parameters.
Stronger eco-film for food packaging and medicine
Exfoliating a copolymer poly(hydroxyalkanoate) with an organoclay increases its tensile modulus.
Coated multi-walled carbon nanotubes for the preparation of nanocomposite films
Purely ß-polymorph poly(vinylidene fluoride) nanocomposite films with improved tensile properties were prepared using polyvinylpyrroli- done-coated multi-walled carbon nanotubes as nanofillers.
Carbon nanotube/polymer composite preparation with improved mechanical properties
A supercritical carbon dioxide green technique was used to disperse entangled carbon nanotubes and led to improved mechanical properties in a carbon nanotube/polymer composite.
Toward more controlled, nanoscale barrier layers in packaging
Understanding adhesion between polymer and alumina helps scale up atomic layer deposition production processes.
Enhancing gas-barrier properties of polymer-clay nanocomposites
The volume fraction of constrained polymer regions correlates with a reduction in permeability.
Masterbatch method to generate polyethylene graphene oxide nanocomposites
Solution mixing of a graphene oxide filler with chlorinated polyethylene compatibilizers, followed by melt mixing of the masterbatch with high-density polyethylene, generated graphene-based nanocomposites.
Antioxidant effects of natural compounds on green composite materials
Naturally-occurring antioxidant compounds can improve the thermal resistance of a bio-composite, increasing the degradation temperature of the material by as much as 130%.
Computerized optimization substantially reduces profile extrusion die design time
A new computational design optimization scheme applied to a complex unplasticized-polyvinyl chloride window profile die delivers high-quality design while truncating design time by 85%.
Determining the aspect ratio of graphene nanocomposites by indirect measurements
The measurement of the engineering properties of nanocomposites provides information about the average degree of graphene filler dispersion.
The effectiveness of carbon nanofiber-based nanocomposites
Heat treating carbon nanofibers improves their electrical conductivity, which in turn increases the electromagnetic shielding effectiveness of their linear low-density polyethylene nanocomposites.
Predicting orientation of long-fiber suspensions
Applying a novel continuum model of semi-flexible fibers demonstrates the potential for improved understanding of long glass fiber behavior in an injection-molded disk.
Improved performance of polypropylene/talc composites
Surface treatment of talc filler by superficial grafting of acetoxy groups improves the yield stress, elongation at break, and toughness of the composites.
