▎ 摘　　要

NOVELTY - Preparing secondary doped graphene oxide/alkali-soluble chitosan-polyaniline-polyacrylamide composite conductive hydrogel involves using one-pot method. The conductive hydrogel material uses an alkali-soluble chitosan hydrogel as a matrix, graphene oxide as a nano-reinforcing component, polyaniline as a conductive component, and polyacrylamide as a reinforcing and toughening component and then immersed in phytic acid solution for secondary doping of polyaniline. USE - Method for preparing secondary doped graphene oxide/alkali-soluble chitosan-polyaniline-polyacrylamide composite conductive hydrogel used in electronic skin, flexible electronic devices and other fields. ADVANTAGE - The method enables to prepare secondary doped graphene oxide/alkali-soluble chitosan-polyaniline-polyacrylamide composite conductive hydrogel, which has excellent mechanical properties and electrical conductivity.
