摘要

聚二甲基硅氧烷（PDMS）是一种用于碳钢表面的防腐涂料，在使用过程中容易剥落和损坏。本研究将六方氮化硼（h - BN）与聚多巴胺进行非共价修饰，制备聚多巴胺修饰的氮化硼（h - BN/PDA），然后将其掺入聚二甲基硅氧烷（PDMS）中制备PDMS/h - BN/PDA复合涂层。结果表明：改性复合涂层的平均摩擦系数为0.43，附着强度达到0.61 MPa，在盐雾和电化学阻抗测试中表现优异。h-BN/PDA的掺入改善了PDMS涂层的缺陷问题，提高了PDMS涂层的整体性能特征。

Preparation and properties of the PDMS/h-BN/PDA composite anti-corrosion coating on a carbon steel surface

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.
