Abstract：The surface pretreatment to electroless-deposited silver on medical polyurethane was studied,such as roughening,sensitizing and activating.Chromium trioxide and potassium permanganate were used as roughening solution,stannous chloride as sensitizing solution,silver nitrate as activating solution.The results show that the optimal roughening parameters are roughing temperature of 40℃,roughening time of 10min,chromium trioxide concentration of 80g/L,sulfuric acid and chromium trioxide mixture ratio of 2:1,the optimal sensitizing parameter is stannous chloride concentration of 10g/L.
