摘      要：The wettability and surface structure of plasma treatment on medical polyurethane were *** kinds of gas,N_(2),Ar,were used to create the dow-temperature plasma under low *** wettability was investigated by means of the sessile drop method using water,the results show that the contact angle of water decreases from 78.8°to 61.9°as the treatment time *** results of electron spectroscopy for chemical analysis indicate that original chemical bonds were broken up after plasma,treatment,which was the main reason for the surface *** same time,the results of electron spinning resonance show that the amounts of radicals did not increase significantly after treatment,which is advantageous to clinical practice of polyurethane.
