WebApr 7, 2004 · Surface modification of high-density polyethylene (HDPE) surfaces by plasma polymerization of glycidyl methacrylate (GMA) (the pp-GMA-HDPE surfaces), in the absence and presence of Ar plasma pre-activation of the HDPE substrates, was carried out to enhance the adhesion of the polymer with evaporated copper. WebSurface segregation of small amounts of additives in a polymer matrix is the most convenient and low-cost method to modify surface properties and functions. Although the surface segregation approach can increase the hydrophobicity of polymer surfaces, it is still a challenge to make the surfaces hydrophilic in an equivalent method.
