A Robust Cu(OH)₂ Nanoneedles Mesh with Tunable Wettability for Nonaqueous Multiphase Liquid Separation

Abstract

The separation of organic liquid mixtures is achieved by Cu(OH)₂ nanoneedle-covered copper mesh based on the difference of the liquid surface tension. The as-prepared membrane allows the penetration of organic liquid with smaller surface tension and blocks the higher. Thus, the effective separation of these two organic liquids can be achieved.
