Abstract
Polydimethylsiloxane (PDMS) is applied as an anti-corrosion coating to the surface of carbon steel which is prone to peeling and damage during use. In this study, hexagonal boron nitride (h - BN) was non - covalently modified with polydopamine to prepare polydopamine - modified boron nitride (h - BN/PDA), which was then incorporated into polydimethylsiloxane (PDMS) to fabricate a PDMS/h - BN/PDA composite coating. The results revealed that the average friction coefficient of the modified composite coating was 0.43, the adhesion strength reached 0.61 MPa, and the performance was excellent in salt spray and electrochemical impedance tests. The incorporation of h-BN/PDA improved the defect issues of the PDMS coatings and enhanced the overall performance characteristics of the PDMS coatings.
期刊介绍：
FlatChem - Chemistry of Flat Materials, a new voice in the community, publishes original and significant, cutting-edge research related to the chemistry of graphene and related 2D & layered materials.
