▎ 摘　　要

NOVELTY - The method involves adding graphene oxide and natural crystalline flake graphite into strong oxidizing acid. Strong oxidizing acid is added into strong potassium acid. Ice water is added with hydrogen peroxide to obtain oxidized graphite suspension. Graphene oxide dispersion liquid is prepared. Ultrasonic dispersion treatment is performed on graphene oxide deionized water. Graphene oxide-carbon nano-tube solution is processed to obtain graphene oxide-carbon nano-tube temperature sponge. The graphene-carbon nano-tube sponge is dried to obtain an ultra-light clothing inner filler. USE - Method for manufacturing a warm light inner filler. ADVANTAGE - The method enables producing a warm light inner filler with high density and better heat coefficient and reducing thickness of clothing so as to provide better warm light effect and aesthetic appearance of the warm light inner filler. DETAILED DESCRIPTION - The strong oxidizing acid is phosphoric acid and sulfuric acid. The graphene oxide-carbon nano-tube temperature sponge is prepared by a carbon nano-tube and surfactant using pre-freezing treatment. The carbon nano-tube is a single-wall carbon nano tube, double-wall carbon nano-tube or multi-walled carbon nanotube. The surfactant is sodium dodecyl benzene sulfonate, sodium dodecyl sulfate or hexadecyl trimethyl ammonium bromide. DESCRIPTION OF DRAWING(S) - The drawing shows a screen shot of a warm light inner filler.
