Superwetting Patterned Membranes with an Anisotropy/Isotropy Transition: Towards Signal Expression and Liquid Permeation

Superwetting membranes with responsive properties have attracted heightened attention because of their fine-tunable surface wettability. However, their functional diversity is severely limited by the "black-or-white" wettability transition. Herein, we describe a coating strategy to fabricate multifunctional responsive superwetting membranes with SiO2 /octadecylamine patterns. The adjustable patterns in the responsive region are the key factor...
