▎ 摘　　要

NOVELTY - A method for improving stability of aramid fiber nanofiber and konjak composite film comprises dissolving graphene oxide and glycerol in konjac glucomannan solution, stirring to form solution adhesive, degassing, forming konjac glucomannan layer (3) by film forming, spraying surface with water, heating to form crosslinked buffer layer (2), uniformly coating with aramid fiber nanofiber solution to form light shielding layer (1) to obtain the composite film, and drying. USE - Method for improving stability of aramid fiber nanofiber and konjak composite film. ADVANTAGE - The composite film comprises a light shielding layer, a cross-linked buffer layer and a konjac glucomannan layer. the light shielding layer can effectively shield the light, realizing light shielding function, and using the waste heat shielding layer to evaporate the internal moisture, the konjac glucomannan layer has strong moisture absorption effect, keeping the drying effect of the stored material, the water in the composite film can enter into the cross-linked buffer layer through the pore passage, waste heat the evaporation effect of the internal water provided by the light shielding layer, and the water of the crosslinking buffer layer has a reduced effect on the sunlight intensity, improving the stability of the composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a structural representation of graphene oxide/aramid nanofiber/konjac glucomannan ternary composite film.
