Antistatic flame-retardant casein-based graphene composite fabric and preparation method thereof

Abstract

The invention particularly relates to an antistatic flame-retardant casein-based graphene composite fabric and a preparation method thereof. The preparation method comprises: preparing graphene oxide(GO) by using an improved Hummers method, and preparing a GO solution to make the GO solution be negatively charged; dissolving casein with a caprolactam-modified acid to make the casein be positivelycharged; and introducing the nanoparticle graphene into the casein matrix by using a layer-by-layer self-assembly method to prepare an antistatic flame-retardant casein-based GO composite fabric, andreducing with NaBH4 to obtain the antistatic flame-retardant casein-based graphene composite fabric. According to the present invention, the prepared antistatic flame-retardant casein-based graphenecomposite fabric has the improved antistatic property and the improved flame retardant property, and is expected to be applied in the fields of leather, food, papermaking and the like.

Description

Technical field The invention belongs to the technical field of composite materials, and specifically relates to an antistatic flame-retardant casein-based graphene composite fabric and a preparation method thereof. Background technique In recent years, environmental protection issues have been concerned by people. As a pure natural protein, casein can synthesize various derivatives due to its good biodegradability, affinity, low cost, and multiple reactive groups in the molecular chain. It is used in leather, paper, textiles and medicine. And other fields are widely used. However, the current application of casein as a coating still has some shortcomings, such as poor antistatic and flame retardant properties, which limits its application range to a certain extent. Graphene is a carbon material with a two-dimensional honeycomb structure. It has a unique monoatomic layered structure and excellent mechanical and thermal properties. It has attracted great attention from researc...
