Slippery liquid infused porous surface (SLIPS) condensers for high efficiency air gap membrane distillation.

ABSTRACT: To address growing water scarcity, we must improve the energy efficiency of thermal desalination technologies such as air gap membrane distillation. However, promising functional materials such as slippery liquid infused porous surfaces have not yet implemented for any desalination technology. Here, we fabricate and test slippery liquid infused porous surfaces (using Krytox 16,256 lubricant and CuO nanostructures) in an air gap membrane distillation apparatus. System-level transport models, validated by experimental data, establish a framework for improving performance through enhanced condensation surfaces. Results are obtained across a range of temperatures (50-80 °C), salinities (5-105 g/kg), and module lengths. We find that small air gap thickness and efficient droplet shedding signifi
