The Coating Property Study of (Meth)Acrylate Copolymer with Gradient Wettability Surfaces

Abstract

The coating property of (meth) acrylate copolymer with gradient wettability surfaces was studied. The random (meth) acrylate copolymers can be obtained according to the free radical polymerization method and their coating property was analyzed according to performance testing. The gradient wettability surface was prepared by using the sodium hydroxide solution. The effects of the kinds of crosslinking monomer, mass ration of HEMA, additional method of HEMA, amount of curing agent and curing temperature on the coating property of (meth) acrylate copolymer were discussed. It was found that the mass ration of HEMA was 15 % and the additional method of HEMA was added previously when the molar ration of MMA/BA was 6/4. The amount of curing agent was 1.86 g and the curing temperature was 160 °C when the P (MMA-BA-HEMA) solutions were 10 g.
