摘要

该研究探讨了掺杂液体润滑剂的聚合物基体涂层的全疏水性(注入液体的光滑多孔表面，slip)与润滑剂中基体的膨胀程度之间的关系。提出了一种在超临界(SC) CO2条件下用不同润滑油含量的氟化油浸渍聚(全氟烷基甲基丙烯酸酯)制备基质的方法。研究了水滴和饱和烃滴的接触角滞后和滑动角与膨胀度的关系。采用热重法和椭偏法测定基质中润滑剂的含量。

Relationship between the Omniphobic Properties and the Swelling Degree of SLIPS Coatings Based on Polymer Gel Thin Films

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.

期刊介绍： Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
