Abstract
Ultra-high molecular weight polyethylene (UHMWPE) containing silver particles was obtained by impregnation with a silver-containing precursor in supercritical carbon dioxide and its microstructure and mechanical properties were studied. The Ag-containing UHMWPE samples showed a 40–50% increase (on the average) in the elasticity modulus according to a study by the nanoindentation method. The hardness of the material did not change during modification. The friction coefficients of the starting and modified samples were comparable over the whole range of loads from 50 to 400 N under study.
