Polymer gels are unique smart materials in the sense that they can respond to many different stimuli. In this paper we report how poly(N-isopropylacrylamide) (abbreviated as PNIPA) and other polymer hydrogels can be used to construct an intelligent gel-glass which can moderate the amount of light and radiated heat. This environmental sensitive glass, which is a smart hydrogel layer placed between two glass or plastic sheets, becomes opaque when the temperature exceeds a critical value. It becomes transparent again if it is cooled down. The adaptive properties of gel-glasses make them a promising materials to protect from strong sunlight and heat radiation.
