Abstract

The invention belongs to the field of high polymer materials and particularly relates to a graphene oxide antibacterial composite PVC material and a preparation method thereof. An antibacterial composite is prepared in the way that nano-silver and nanometer titania are loaded on graphene oxide, and zinc oxide capable of improving the optical activity of titania is added, so that the antibacterial performance is greatly improved. The mechanical property and structural characteristics of graphene oxide are given into full play, so that nano-silver and nanometer titania can be closely combined with graphene oxide and a PVC material, and the function is effective for a long time. The mechanical property of the material is enhanced while the antibacterial effect is improved, the preparation technological conditions are mild, and the graphene oxide antibacterial composite PVC material is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a graphene oxide antibacterial composite polyvinyl chloride material and a preparation method thereof. Background technique [0002] Since Graphene was reported by Andre Geim, a professor at the University of Manchester in 2004, it has attracted widespread attention and great interest from scientists due to its unique properties, and it is predicted that it is likely to be used in revolutionized many fields. Graphene is a two-dimensional honeycomb crystal composed of hexagonal cells of carbon atoms, with a thickness of only 0.334nm. It is the basic unit for constructing carbonaceous materials of other dimensions. Graphene oxide is generally obtained by oxidation of graphite with strong acid. It is a new type of carbon material with excellent performance. It has a high specific surface area and abundant functional groups on the surface. Graphene oxide composites, in...
