Abstract We developed two-coat polymeric nanocomposite coatings for the protection of steel structures from the thermal and corrosive environment. To protect the steel structures, the coating selectivity is crucial; we have chosen the coating such way, the coated surface has low surface energy polymer which has low surface polarity. The polymer nanocomposite coatings were prepared using polydimethylsiloxane with an optimal amount of zirconia nanoparticle. The incorporation of zirconia nanoparticle has extended the thermal stability and efficient corrosion protection of steel substrates. The formulated coatings exhibited a superhydrophobic characteristic with CA-165° and low contact angle hysteresis (

用于热管理应用中换热器通道的自补充超疏水耐用聚合物纳米复合涂层

摘要 我们开发了两层聚合物纳米复合涂层，用于保护钢结构免受热和腐蚀环境的影响。为了保护钢结构，涂层的选择性至关重要；我们选择了这样的涂层，涂层表面具有低表面能聚合物，具有低表面极性。使用聚二甲基硅氧烷和最佳量的氧化锆纳米颗粒制备聚合物纳米复合涂层。氧化锆纳米粒子的加入扩展了钢基材的热稳定性和有效的腐蚀保护。配制的涂层表现出超疏水特性，CA-165°和低接触角滞后（
