▎ 摘　　要

NOVELTY - Carbon sponge is claimed. The carbon sponge is formed by graphene or partially reduced graphene oxide and amorphous carbon via a brick mud structure, where the brick mud structure refers to single layer or multiple layers of graphene or partially reduced graphene oxide as a brick, and the amorphous carbon as a mud, coating or partially coating the graphene or partially reducing graphene oxide, in which a graphene or partially reduced graphene oxide and amorphous carbon are joined to form a porous network structure of brick structure. The weight percentage of its components of graphene or partially reduced graphene oxide is 0.1-99.9 wt.% and amorphous carbon is 0.1-99.9 wt.%. USE - Used as carbon sponge. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing a compressible superelastic carbon sponge comprising dispersing an additive and graphene oxide in a solvent to obtain mixed solution of graphene oxide and additive, then drying the mixed solution to obtain oxide-containing graphene sponge containing an additive and heat-treating the additive-containing graphene oxide sponge under high temperature protection; and (2) tactile and pressure sensor for detecting the tactile and pressure of any direction of the carbon sponge and the electrode is connected with the carbon sponge and measuring device for electrical signal between electrode and carbon sponge.
