Problems solved by technology

However, due to the relatively few reactive groups on the surface of graphene, the compatibility and interaction with other materials are poor. When the graphene aggregates seriously, it will cause bubbling on the surface of the PVC material, resulting in a decrease in its anti-corrosion performance.

Abstract

The invention discloses a preparation method of an anti-corrosion flexible PVC decorative film, which comprises the following steps: carrying out oxidation modification on a multi-walled carbon nanotube to obtain an oxidized multi-walled carbon nanotube; the preparation method comprises the following steps: preparing graphene oxide by using a Hummer method, and then reducing GO powder by using a high-temperature thermal reduction method to obtain reduced graphene oxide (RGO); preparing dispersion liquid; adding PVC and 30ml of polyethylene glycol into the dispersion liquid, fully stirring at room temperature, and standing for defoaming; and taking out the membrane casting solution, uniformly coating a glass plate with the solution at room temperature, and naturally airing at room temperature to obtain the corrosion-resistant flexible PVC membrane. The surface of the functionally modified multi-walled carbon nanotube contains a large number of hydroxyl groups, so that graphene can be dispersed more efficiently; the addition of polyoxometallate can catalyze the formation of a graphene intercalation by the multi-walled carbon nanotubes, improve the graphene agglomeration phenomenon and increase the available specific surface area of graphene.
