▎ 摘 要
NOVELTY - Preparing composite gel involves reacting graphene oxide and p-phenylenediamine are reacted to obtain graphene containing phenylamino group. The aniline and graphene containing phenylamino group are sunjected to hydrothermal reaction, obtaining polyaniline/graphene composite gel. The composite gel obtained is placed in a polyvinyl alcohol solution for cyclic freezing and thawing treatment. USE - Method for preparing composite gel used for preparing capacitor. ADVANTAGE - The method enables to prepare composite gel in a simple manner with wide applicability.
