In the present work, a novel one-stage approach to the creation of omniphobic surface using supercritical carbon dioxide as a solvent is proposed. Poly(perfluorohexyl ethyl methacrylate - hydroxypropyl methacrylate) copolymer cross-linked with hexamethylene diisocyanate is used as a polymer matrix, and polyoxaperfluorobutyl bromide (oil) is used as a lubricant. Oil content in the obtained films is measured by thermogravimetry and compared with the classical Flory-Rehner theory. It is shown that the addition of fluorinated oil to the synthesis process results in a significant decrease of apparent contact angle hysteresis and sliding angles of the obtained gel thin films. The proposed technique may be of interest for SLIPS application on surfaces with a complex structure like fabrics.

在本工作中，提出了一种使用超临界二氧化碳作为溶剂来形成全疏表面的新颖的一阶段方法。与六亚甲基二异氰酸酯交联的聚（甲基丙烯酸全氟己基乙酯-甲基丙烯酸羟丙酯）共聚物用作聚合物基质，而聚氧杂全氟丁基溴化物（油）用作润滑剂。通过热重法测量获得的膜中的油含量，并将其与经典的Flory-Rehner理论进行比较。结果表明，在合成过程中添加氟化油会明显降低所得凝胶薄膜的表观接触角滞后和滑动角。对于具有复杂结构（如织物）的表面上的SLIPS应用，所提出的技术可能是令人感兴趣的。
