Abstract

A water delivery device used, for example, for controlling moisture in a plant growing medium or for a water purification device; the device comprises a water vapor permeable non porous hydrophilic membrane of a polymer blend of one or more thermoplastic polyether-ester polymer(s) and a liquid crystalline thermotropic polyester; and wherein the membrane has a water vapor transmission rate of at least 400 g/m2/24 hrs measured according to ASTM F-1249 -90 on a film 3 mils (76.2 microns) thick using air at 30°C and 100% relative humidity at a velocity of 3 m/s and the polymer blend has a linear expansion of less than 7% measured on a fully hydrated film of the polymer blend; whereby an aqueous liquid comprising water is placed in contact with the membrane and water passes through the membrane by pervaporation to, for example, a plant growing medium thereby controlling the moisture in the medium or water can be collected and used as purified water.
