Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to an MXene-graphene-PVC composite material and a preparation method thereof. The MXene-graphene-PVC composite material is prepared from the following raw materials in parts by weight: 100 parts of PVC resin, 1 to 5 parts of a heat stabilizer, 3 to 15 parts of chlorinated polyethylene, 1 to 4 parts of an ACR processing aid, 1 to 20 parts of nano calcium carbonate, 0.3 to 2 parts of a lubricant, 1 to 5 parts of MXene-graphene and 0.1 to 0.5 part of an antioxidant. The MXene-graphene is prepared by the following steps: firstly, modifying graphene oxide by using amino molecules, then intercalating MXene into the graphene oxide, and finally reducing to obtain MXene-graphene. According to the invention, electrostatic repulsion among graphene sheet layers is increased, and aggregation of graphene in a PVC matrix is effectively reduced. Meanwhile, the dispersity, the conductivity and the toughness of the PVC composite material are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to MXene-graphene-PVC composite material and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional material with a unique structure composed of a single layer of carbon atoms. Among them, each carbon atom forms a covalent bond with three surrounding carbon atoms, forming a two-dimensional structure with continuous conjugated benzene six-membered ring as the basic unit. The unique two-dimensional conjugated structure of graphene determines that it will have unique properties, such as excellent room temperature electrical conductivity and thermal conductivity, good mechanical and mechanical properties, huge specific surface area and stable physical and chemical properties, making graphene It has great application potential in many fields. Also as a two-dimensional material, titanium carbide transition metal nanosheet MXene ha...
