A composite cooling film (100) comprises an antisoiling layer (160) secured to a first major surface of a reflective microporous layer (110). The reflective microporous layer (110) comprises a first fluoropolymer and is diffusely reflective of electromagnetic radiation over a majority of wavelengths in the range of 400 to 2500 nanometers. The antisoiling layer (160) has an outwardly facing antisoiling surface (162) opposite the micro-voided polymer film. An article (1100) comprising the composite cooling film (1112) secured to a substrate (1110) is also disclosed.

An atmospheric water generator for extracting water droplets from ambient air includes an insulating substrate, a plurality of electrode film units, and a liquid crystal/polymer composite film. Each of surface regions of the liquid crystal/polymer composite film has a plurality of liquid crystal molecules each having a hydrophilic functional group and a hydrophobic moiety. Each of the surface regions normally has one of hydrophilic and hydrophobic properties. When a voltage is applied to one of the electrode film units, the respective surface region is switched to have the other one of hydrophilic and hydrophobic properties, to thereby allow the water droplets condensed from the ambient air to move on the surface regions.
