In this work, poly(dimethyl siloxane) (PDMS) films were modified using poly(2-hydroxyethyl methacrylate) (PHEMA) by sequential method of interpenetrating polymer networks (IPNs). The surface properties of samples were characterised by water contact angle measurements. The results showed that the hydrophilicity of PDMS/PHEMA IPN increased as the content of PHEMA increased.
