Cerium Methacrylate Assisted Preparation of Highly Thermally Conductive and Anticorrosive Multifunctional Coatings for Heat Conduction Metals Protection

Abstract

Highlights Cerium methacrylate was prepared and ingeniously used as curing agent for epoxy, surface modifier for BN, and effective corrosion inhibitor. The coating integrates high thermal conductivity (4.29 W m−1 K−1), corrosion resistance (low-frequency impedance is 5.1 × 1011 Ω cm2 at 181 day), hydrophobicity (WCA: ~ 148.35° and WSA: ~ 20°), temperature resistance and adhesion. The coating can extend service life of metal materials without sacrificing their inherent heat conduction property.
