中文摘要:
      目的 将海胆状纳米二氧化硅(KCC-1)微球掺入聚偏氟乙烯(PVDF)中,制备出KCC-1/PVDF超疏水涂层,并在此基础上利用不同涂层修饰剂修饰,进一步制备出超滑涂层。方法 以溴化十六烷基吡啶作为模板,结合煅烧法合成了海胆状KCC-1微球,分散到PVDF溶液中,在镁合金表面制备KCC-1/PVDF涂层,并进一步用不同修饰剂(全氟辛基三乙氧基硅烷(PFOTES)、十六烷基三甲氧基硅烷(HDTES)和二甲基硅油)对涂层表面进行改性。结果 经过十六烷基三甲氧基硅烷改性,得到水接触角为155°的超疏水涂层,而灌注二甲基硅油后得到滑动角为4.5°的超滑表面。摩擦磨损实验中,超滑表面的耐磨性优于超疏水表面,优于空白镁合金;防覆冰实验结果表明超疏水和超滑表面能有效延缓液滴在表面结冰。结论KCC-1/PVDF超疏水与超滑涂层能有效地保护镁合金基底,且超滑涂层的防腐蚀性优于超疏水涂层,其腐蚀抑制效率IE分别为100%和98.28%。
英文摘要:
      The work aims to prepare KCC-1/PVDF superhydrophobic coatings by incorporating silica (KCC-1) microspheres into polyvinylidene fluoride (PVDF) and then prepare ultra-slip coatings by using different coating modifiers on this basis. KCC-1 microspheres were synthesized by calcination with cetylpyridinium bromide as a template and dispersed in polyvinylidene fluoride (PVDF) solution to prepare KCC-1/PVDF coating on the surface of magnesium alloy. Then, the surface of KCC-1/PVDF coating was modified with different modifiers (PFOTES, HDTES and dimethicone). After the modification with HDTES, a superhydrophobic coating with a water contact angle of 155° was obtained. Added with dimethicone, an ultra-slip surface with a sliding angle of 4.5° was obtained. In the friction and wear test, the wear resistance of the ultra-slip surface was better than that of the superhydrophobic surface and the blank magnesium alloy. The results of the anti-icing experiment showed that the superhydrophobic and ultra-slip surfaces could effectively delay the freezing of droplets on the surface. The KCC-1/PVDF superhydrophobic and ultra-slip surfaces can effectively protect the magnesium alloy substrate and the ultra-slip coating is superior to the superhydrophobic coating in corrosion resistance, of which the corrosion inhibition efficiency IE% is 100% and 98.28%, respectively.
