The effect of heat treatment on gradient wetting of (meth) acrylate polymer film surfaces was analyzed. Poly (methyl methacrylate – butyl acrylate) and poly (methyl methacrylate – butyl acrylate - 2-hydroxyethyl methacrylate) were prepared by the free radical solution polymerization and their coating film wettability was obtained by measuring water contact angles (CAs). The gradient wetting surface was fabricated by a simple controlled ester group hydrolysis process on (meth) acrylate polymer film. The gradient wetting properties were attributed to the gradient surface chemistry from the ester group to acid salt on copolymer film. The copolymer films of gradient wetting were heated at 100 °C. It is found that the gradient materials will exhibit the unique wetting with the heating time increasing and the heat-resistance property of gradient surface needs further research.
