▎ 摘　　要

NOVELTY - Three-dimensional (3D) printed aerogel based on graphene oxide comprises 0.5-5 mg/ml graphene oxide aqueous dispersion with 5-200 mu m average size. USE - Three-dimensional printed aerogel based on graphene oxide used for Joule heating and electromagnetic shielding in piezoelectric sensor. ADVANTAGE - The aerogel has simple preparation method, excellent conductivity and density, strong resilience and high heat resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of 3-D printed aerogel based on graphene oxide comprising adding graphene oxide into 3-D printing material storage bin at normal temperature, printing out graphene oxide body to obtain 3-D printing graphene oxide product, freeze drying or supercritical drying to obtain graphene oxide aerogel, and subjecting into in-situ chemical reduction and high temperature heating.
