NOVELTY - Preparing a konjac glucomannan composite film comprises (a) eluting the konjak fine powder, drying, grinding and sieving to obtain konjac glucomannan, (b) adding glycerin, silver bromide and water, stirring to obtain a mixture, and adding graphene oxide to the mixture, stirring, (c) preparing an aramid fiber sol film, (d) mixing and stirring the mixture to obtain an nano-fiber nano-sol film, and (e) drying the film and the aramid sol film at high-temperature to obtain the film. USE - The konjac glucomannan composite film used in food fresh-keeping aspect, special medicine, fruit and vegetable transportation. ADVANTAGE - The method solves the compatibility problem of the aramid fiber and konjac glucomannan, improves the mechanical strength and stability of thin film, and graphene oxide improves the enhancing effect of the konjak fiber.
