Abstract

In this study, 1-hydroxycyclohexyl phenyl ketone (HCPK) was used as a photo initiator, methacrylic acid (MAA), 2-(dimethylamino)ethyl methacrylate (DMAEMA), and trimethylol-propane trimethacrylate (TMPTMA) were copolymerized by UV polymerization to prepare transparent and flat copolymer films with different monomer ratios. Surface energy was measured using a contact angle meter. We found that the addition of TMPTMA reduced the surface energy of the copolymer films. The water content test also confirmed that the addition of TMPTMA inhibited water absorption. In the dynamic mechanical test, the higher the MAA content, the higher the glass transition temperature (Tg) of the copolymer film, and the addition of TMPTMA also slightly increased the Tg.
