Abstract—Coatings are made using SKTN-f methylphenylsiloxane rubber with different contents of PMS-200 polymethylsiloxane oil and BS-100 white carbon nanoparticles. The authors studied the abrasion resistance and hydrophobic properties (wetting angle, roll-off angle) of coatings and ice adhesion to their surfaces. It is shown that the introduction of polymethylsiloxane oil into the polymer matrix decreases abrasion resistance and hydrophobic properties of the coatings, while at the same time reducing surface ice adhesion. It was established that the introduction of BS-100 nanoparticles can increase the physicomechanical characteristics of coatings while maintaining the level of functional properties. The obtained results for the dependence of functional properties on the chemical composition of the coatings are explained by their structural features; in particular, polymethylsiloxane oil is evenly distributed over the bulk of the polymer matrix, enveloping agglomerates of white carbon nanoparticles emerging on the surface, thereby forming a multimodal roughness, which in turn increases the hydrophobic properties of coatings.

二氧化硅纳米颗粒对有机硅涂层表面性能影响的研究

摘要-使用具有不同含量的PMS-200聚甲基硅氧烷油和BS-100白碳纳米粒子的SKTN-f甲基苯基硅氧烷橡胶制成涂料。作者研究了涂层的耐磨性和疏水性(润湿角,滚落角)以及冰在其表面的附着力。结果表明,将聚甲基硅氧烷油引入聚合物基体会降低涂层的耐磨性和疏水性,同时降低表面冰的附着力。已确定,引入BS-100纳米颗粒可以提高涂层的物理机械特性,同时保持功能特性水平。功能性质对涂层化学成分的依赖性所获得的结果由其结构特征来解释。
