Acrylic coatings with surprising antifogging and frost-resisting properties.

We report an unusually effective antifogging/frost-resisting coating based on conventional acrylic polymers. The intriguing antifogging property originated from the delicate balance between the hydrophilicity and hydrophobicity of the acrylic copolymers of 2-(dimethylamino)ethyl methacrylate and methyl methacrylate, as well as between the water-swellability of the copolymer and the cross-linked network due to ethylene glycol dimethacrylate.
