Abstract
The present disclosure relates to a polyimide-graphene composite material and a method for preparing same. More particularly, it relates to a polyimide-graphene composite material prepared by adding modified graphene and a basic catalyst during polymerization of a polyimide precursor so as to improve mechanical strength and electrical conductivity and enable imidization at low temperature and a method for preparing same.
