▎ 摘　　要

NOVELTY - Polyamic acid composition comprises graphene oxide. USE - The polyamic acid composition is useful for a polyimide film (claimed) that is used in aerospace and electronics industries. ADVANTAGE - The polyamic acid composition increases the electric conductance and mechanical strength of the polyimide film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing polyamic acid composition comprising: carrying out oxidation of graphite oxide to graphene; reducing a portion of graphene oxide; and adding reduced graphene oxide to polyamic acid.
