Abstract

The invention relates to a method for preparing a copper-based nanometer zinc oxide-polyvinylidene fluoride composite material. The method comprises the following specific preparation steps: (1) preparing a zinc oxide nanometer cone film through a chemical bath deposition method in a hot bath by taking a copper sheet as a base material; (2) preparing an azo dimethyl formamide solution with low solid content of polyvinylidene fluoride; (3) preparing a polyvinylidene fluoride film on the surface of the zinc oxide nanometer cone film through a heat curing film formation method to obtain a copper-based nanometer zinc oxide-polyvinylidene fluoride composite film material with certain hydrophobicity, wherein the copper-based nanometer zinc oxide-polyvinylidene fluoride composite film material can be widely applied to the surface modification of a copper-based material and applied to the field of piezoelectric and ferroelectric materials in future. The method disclosed by the invention has the advantages of simple preparation process and low cost and is beneficial to industrial operation and production.
