▎ 摘　　要

NOVELTY - Preparing high performance graphene/cellulose self-assembling composite hydrogel comprises (i) soaking cellulose raw material, easing preparation of pulp dispersion, (ii) taking graphite oxide, adding pulp dispersion, ultrasonic dispersing, obtaining graphene oxide/cellulose mixed solution, and (iii) adding reduction agent in graphene oxide/cellulose mixed solution, at 40-100 degrees C, reducing for 3-24 hours, or using hydro-thermal reduction method, obtaining the product through washing, preparing graphene/cellulose self assembling composite hydrogel. USE - The method is useful for preparing high performance graphene/cellulose self-assembling composite hydrogel (claimed). ADVANTAGE - The method is simple, prepares gel with good performance, particularly conductivity and heat stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing high performance graphene/cellulose self-assembling composite aerogel, by drying hydrogel to obtain composite aerogel; and (2) high performance graphene/cellulose self-assembling composite hydrogel and high performance graphene/cellulose self-assembling composite aerogel.
