Abstract(#br)Very thin polydimethylsiloxane (PDMS)-layer with a mean thickness of 3–5\u003cce:hsp sp=\"0.25\"/\u003enm was formed on Cu particles by using thermal evaporation of PDMS at 200\u003cce:hsp sp=\"0.25\"/\u003e°C under nitrogen atmosphere. Using X-ray photoelectron spectroscopy and FT-IR, it was shown that the dimethylsiloxane framework was sustained after evaporation of PDMS and its deposition on Cu particles.

摘要( # br )超疏水薄膜在应用中的最大障碍之一是其较差的机械阻力。本研究将粗糙电沉积的SiO2 ( E-SiO2 )薄膜与表面能较低的耐用聚二甲基硅氧烷( PDMS )聚合物结合，在温和钢( MS )上构建了用于腐蚀防护的鲁棒超疏水SiO2薄膜。结果表明，PDMS含量对最终薄膜的微观形貌、润湿性、粗糙度和耐磨性有较大影响。EIS测试结果表明，在3.5 wt . % NaCl溶液中，所制备的超疏水E-SiO2 / PDMS薄膜对MS基体具有高达99.99 %的缓蚀效率。
