Micro-structured surfaces can provide useful material properties, such as repellency to water, oil, or alcohols. Multiple polymers were investigated based on micro molding replication fidelity of repellent structures using both advancing and receding contact angle measurements. Five different polymers (Loctite 3525, ST-1060, TC-854, TC-8740, and Teflon AF) were chosen based on a range of durometers, for each of which, a recommended curing process was presented. These polymers were micro-structured via a one-step replica molding to create mushroom shaped fibers with overhanging caps. Teflon AF, a low surface energy polymer, produced innovative superhydrophobic as well as oleophobic Micro Surface Topographies (MSTs). Advancing contact angles (CAs) of these microstructures were 166 ± 4.2, 151 ± 2.9, and 119 ± 2.2 when in contact with a water, ethylene, and olive oil droplet respectively. The highest reproducibility was achieved by using a curing procedure of 100 °C for 2 h. However...

超疏水和疏油聚合物微表面形貌的重现性

微结构表面可以提供有用的材料特性，例如对水，油或醇的排斥性。使用前进和后退接触角测量，基于驱虫结构的微模塑复制保真度，研究了多种聚合物。根据一系列的硬度计，选择了五种不同的聚合物（乐泰3525，ST-1060，TC-854，TC-8740和Teflon AF），每种聚合物均提出了建议的固化工艺。通过一步复制模制法将这些聚合物微结构化，以形成带有悬垂帽的蘑菇形纤维。低表面能聚合物Teflon AF产生了创新的超疏水以及疏油微表面形貌（MST）。与水接触时，这些微结构的前进接触角（CAs）为166±4.2、151±2.9和119±2.2，乙烯和橄榄油滴。通过使用100°C的固化程序2 h，可获得最高的可重复性。然而...
