The mechanical characteristics of ionic-covalent entanglement hydrogels consisting of combinations of the biopolymers gellan gum and kappa-carrageenan, and the synthetic polymers polyacrylamide and an epoxy amine were investigated. Compression testing showed that these gels exhibited "double network" behavior, i.e. strong tough gels.

Composites with nanoparticles and polymers can improve the functionalities and existing formulations. In this work we synthesized Graphene Oxide and is incorporated into an epoxy based negative tone photoresist in different weight percentages. Thermal conductivity studies were carried out on those composites and it was found that 13 % by weight is the optimized loading to have an enhanced therm...

We report the design and synthesis of a polymer structure from a cross-linkable epoxy-ionic liquid system which behaves like a hard and brittle epoxy thermoset, perfectly ductile thermoplastic and an elastomer, all depending on controllable network compositions.

The effect of nanoclay on various material properties like damping and strength of typical thermoset polymers, such as epoxy and vinyl ester, was investigated. Different environmental conditions typical for high-voltage transmission pylons made of composite materials were taken into account. Resin samples were prepared with various clay weight fractions ranging from 0% to 3%. Scanning electron ...

Syntactic foams are lightweight, high specific strength materials used in the aerospace and naval industries. Their utility is limited by their brittleness. The epoxy polymer matrix an epoxy/hollow glass microsphere (GMS) syntactic foam was modified using carboxyl-terminated butadiene-acrylonitrile (CTBN) rubber with aim to increase fracture toughness. microstructure properties were investigate...
