摘　　要：随着高分子化学的发展对建筑装饰材料的性能提出了一定要求。选择碳钢作为测试基材,利用碱性不含氰化物电解浴方式制备有机硅聚合物(PDMS)装饰涂层,对PDMS涂层进行聚四氟乙烯(PTFE)改性处理形成超疏水表面。开展实验测试研究其表面润湿性和耐腐蚀性。研究结果表明:PDMS涂层润湿角从31.6°提高至81.5°,经PTFE修饰处理的试样获得了超疏水性。PDMS涂层形成了2个抑制阳极反应的钝化区,获得了更强的耐蚀能力。PDMS涂层PTFE改性后具备比改性前更强耐蚀能力。该研究有助于提高建筑装饰材料表面使用效率,尤其是便民质量。With the development of polymer chemistry,certain requirements have been put forward for the performance of architectural decoration materials.Silicone polymer(PDMS)decorative coating was prepared by alkaline cyanide-free electrolytic bath using carbon steel as test material.The PDMS coating was modified by polytetrafluoroethylene(PTFE)to form superhydrophobic surface.The surface wettability and corrosion resistance were studied by experiments.The results showed that the wetting angle of PDMS coating increased from 31.6°to 81.5°,and the PTFE modified sample obtained superhydrophobicity.The PDMS coating formed two passivation zones to inhibit the anode reaction and obtained stronger corrosion resistance.PDMS coating has stronger corrosion resistance after PTFE modification than before modification.This research is helpful to improve the surface efficiency of architectural decoration materials,especially the quality of convenience.
