▎ 摘　　要

NOVELTY - Preparing regenerated cellulose fiber/aerogel composite material comprises (i) adding 5-10 pts. wt. sodium hydroxide, 5-10 pts. wt. urea, 1-5 pts. wt. graphene oxide, and 0.5-2 pts. wt. surfactant into 100 pts. wt. water, ultrasonically treating for 10-30 minutes, and preparing into mixed solution; (ii) adding 1-5 pts. wt. cellulose into mixed solution and stirring evenly to obtain a cellulose mixed solution; (iii) spreading the regenerated cellulose substrate in the mold, adding the cellulose mixed solution to cover the surface of all regenerated cellulose substrates, and obtaining the primary composite material template; and (iv) adding sulfuric acid or hydrochloric acid to treat the primary composite template, washing with water, freezing at low temperature, and freeze-drying. USE - The regenerated cellulose fiber/aerogel composite material is useful in fields of clothes and home textile (claimed). ADVANTAGE - The regenerated cellulose fiber/aerogel composite material: has excellent mechanical strength, thermal insulation performance, antibacterial performance and lightweight. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the regenerated cellulose fiber/aerogel composite material is prepared by above mentioned method.
