Polymer nanocomposites offer enhancement in thermomechanical and physicochemical properties of polymers with the presence of a little amount of nanostructured fillers such as carbon nanotubes, graphene, and layered silicates. A facile and rapid preparation of hytrel (HTL)-graphene oxide (GO) nanocomposites is done via a solution mixing method. The influence of GO content (0.1, 0.5, 1, 2, and 5 wt%) on mechanical and thermal properties of GO/HTL nanocomposites has been evaluated by using various techniques such as tensile testing, thermogravimetric analysis, differential scanning calorimetry, and dynamic mechanical analysis. The thermal stability and mechanical properties of GO/HTL nanocomposites were increased with increasing GO content. The composites have valuable improvement in tensile strength (139%) and storage modulus (72%) for HTL composite containing 5 wt% GO. The incorporation of GO into HTL polymer shows enhancement in thermal and mechanical properties due to the presence of strongest noncovalent interaction (π–π stacking) between the interface of nanocomposites. These enhanced physical properties of GO/HTL composites show its potential use in structural application.

The demand for energy and energy storage devices is the urgent need of our society due to heavy dependence on electric appliances. Hence, the demand of graphene-like smart materials has grown tremendously in the past years. Herein, we investigated the binder-free graphene allies named reduced graphene oxide (rGO) as electrode materials for the supercapacitor after the reduction of graphene oxide by sinking and leaving process. The rGO-based devices show the areal specific capacitance of 80.2 and 7.89 mF cm−2 with aqueous 1M phosphoric acid (H3PO4) and poly (vinyl alcohol)-H3PO4 polymer gel electrolytes, respectively, over the graphite sheet.

Presently, waste plastic management is one of the burning issue across the globe which is not easy to resolve. We made an attempt to resolve this issue and make the...
