Electrical and Thermal Properties of Nanocomposites Based on Poly Lactic Acid/ Graphene Used in PEM Fuel Cell

The electrical properties and thermal decomposition kinetics of modified and non-modified nanocomposite of poly lactic acid (PLA) / Graphene were investigated. The thermal decomposition kinetics were determined by Flynn-Wall-Ozawa (FWO) model, which would define the thermal stability of the nanocomposites through the determination of their decomposition activation energies. It is obvious that modified nanocomposites had higher resistance to thermal degradation due to their higher activation energies. Furthermore, it was found that the nanocomposites contains functionalized graphene, have lower electrical conductivity
