Abstract

The study addresses the relationship between the omniphobic properties of coatings based on polymer matrices doped with liquid lubricants (Slippery Liquid-Infused Porous Surfaces, SLIPS) and the degree of swelling of the matrices in the lubricant. A method for fabrication of matrices based on poly(perfluoroalkyl methacrylates) impregnated with fluorinated oils with different lubricant contents by one-stage synthesis in supercritical (SC) CO₂ is proposed. The dependence of the contact angle hysteresis and the sliding angle on the degree of swelling was studied for water and saturated hydrocarbon droplets. The lubricant content in the matrices was determined by thermogravimetric analysis and ellipsometry.

基于聚合物凝胶薄膜的SLIPS涂层的疏水性与溶胀度的关系

摘要

该研究解决了基于掺杂有液体润滑剂的聚合物基质（光滑液体注入多孔表面，SLIPS）的涂层的全疏水特性与润滑剂中基质溶胀程度之间的关系。提出了一种基于聚（甲基丙烯酸全氟烷基酯）浸渍具有不同润滑剂含量的氟化油的基质的方法，该方法通过在超临界 (SC) CO ₂中的一步合成进行。研究了水和饱和烃液滴的接触角滞后和滑动角对溶胀度的依赖性。基质中的润滑剂含量通过热重分析和椭圆偏光法测定。
