Abstract

The invention discloses an electrostatic dust collection graphene oxide nano composite material, a preparation method and application, and belongs to the technical field of nano materials and electrostatic dust collection. The composite material is prepared from a metal coordination polymer and graphene oxide through in-situ bonding and thermal reduction, and the core is to introduce a PEG-PS micelle regulation and control system synthesized by an ATRP (Atom Transfer Radical Polymerization) method to inhibit material agglomeration so as to form a regular nano array structure. The graphene oxide is a two-dimensional conductive substrate, the long-strip nanoflower-shaped metal coordination polymer is uniformly attached to the surface of the graphene oxide, and the graphene oxide and the long-strip nanoflower-shaped metal coordination polymer synergistically endow the material with high conductivity, large specific surface area and excellent stability. The preparation process is environment-friendly and controllable by accurately regulating and controlling the raw material ratio and process parameters. The dust removal rate of the composite material exceeds 98%, the problems that a traditional material is low in efficiency, prone to agglomeration and the like are solved, and the composite material is an ideal high-performance electrostatic dust removal nano electrode material and wide in application prospect.
