本研究使用了一种NP-GLIDE涂层，该涂层含有用于脱湿的接枝润滑成分的基质纳米池和润滑剂聚二甲基硅氧烷（PDMS）。此外，一种注入硅的NP-GLIDE （SINP-GLIDE）涂层在其基体纳米池中含有由接枝的PDMS链稳定的硅油混合物。此外，当pdms稳定硅油池的直径与可见光波长相当时，涂层是预滑移（光滑的液体注入多孔表面）。在本研究中，在没有或存在硅油混合物的情况下，使用Jeffamine固化双酚A二缩水甘油酯醚（DGEBA）和聚（甲基丙烯酸缩水甘油酯）-接枝聚（二甲基硅氧烷）（PGMA-g-PDMS），制备了NP-GLIDE、SINP-GLIDE和预slip涂层。在预slip薄膜的表面添加硅油后，获得了slip涂层。预slip配方也被浇铸在粗糙的基板上，以产生超疏水涂层。除了各种涂层的制备，本文还报道了不同涂层的光学和脱湿性能，以及描述涂层类型与PDMS及其硅油质量分数之间关系的相图。这一比较研究的结果有助于为有针对性的应用选择涂层。
An NP-GLIDE coating contained in matrix nanometer-sized pools of a grafted lubricating ingredient for dewetting enablement and lubricant poly(dimethyl siloxane) (PDMS) was used in this study. Furthermore, a silicone-infused NP-GLIDE (SINP-GLIDE) coating contained in its matrix nanopools of a silicone oil mixture that was stabilized by the grafted PDMS chains. Also, the coating was a pre-SLIPS (slippery liquid-infused porous surface) when the diameter of the PDMS-stabilized silicone oil pools became comparable with the wavelength of visible light. In this study, NP-GLIDE, SINP-GLIDE, and pre-SLIPS coatings were prepared from curing bisphenol A diglycidyl ether (DGEBA) and poly(glycidyl methacrylate)-graft-poly(dimethyl siloxane) (PGMA-g-PDMS) using Jeffamine in the absence or presence of a silicone oil mixture. The SLIPS coatings were obtained after additionally dosing the surfaces of the pre-SLIPS films with silicone oil. A pre-SLIPS formulation was also cast onto a rough substrate to yield a superhydrophobic coating. Besides the preparation of the various coatings, herein, we report the optical and de-wetting properties of the different coatings and phase diagrams describing the relationship between the coating types with PDMS and their silicone oil mass fractions. The results of this comparative study facilitate the choice of coating for targeted applications.
