▎ 摘　　要

NOVELTY - Graphene roll/carbon nanotube composite aerogel material comprises graphene and carbon nanotubes forming three-dimensional network of skeleton structure. The graphene is wrapped with carbon nanotube. The carbon nanotube runs through graphene sheet between layers. USE - Graphene roll/carbon nanotube composite aerogel material used as flexible electrode or stress sensing material (claimed). ADVANTAGE - The material has porous structure and good compression. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene roll/carbon nanotube composite aerogel material comprising ultrasonic dispersing graphene oxide in deionized water, then acidified carbon nanotubes in deionized water, ultrasonic mixing both solutions, quenching in liquid nitrogen, freeze-drying and carbonizing.
