|Summary||We have found that swelling the surface of ultra high molecular weight polyethylene (UHMWPE) with an organic solvent and then subsequently cooling with the solvent present can significantly modify surface properties. In particular, metal/polymer adhesion can be enhanced and, if graphite is added to the solvent, surface conductivity can be enhanced. The enhanced adhesion properties may relate to an increased ductility of the preswollen polymer at elevated temperatures. The modified conductivity can be attributed to graphite particles trapped at the surface of the material. In order to qualitatively explain some of our results, rheological and optical observations on UHMWPE melts are also presented. © 1992.|
