Desired structural characteristics of the active (nano-porous) layer and the support (micro-porous) layer including the range of pore size and thickness for each layer, as well as the active layer hydrophobicity and water contact angle \(\theta\) that will achieve a drastic increase in the driving force (vapor pressure difference) with a very small temperature gradient, removing the requirement of large sensible heat supply to the feed solution.
