摘　　要：采用不同质量比的聚乙烯基吡咯烷酮一聚氨酯半互穿网络体系修饰聚氨酯表面。对修饰后的材料表面进行接触角、吸水速率、静摩擦系数、滑动时间等指标测定。结果表明，修饰后的材料表面亲水润滑性得到了明显提高，并得出了最佳的聚乙烯基吡咯烷酮与聚氨酯用量比。PU surface is m0dified with Send-inmpnetrating network systems of Polyviny pyrrolidine -polyurethaneurea with different mass rates. Its contact angle, water absorption rate, motionless fric-tion coefficient and sliding time are respecivey tested. The results show that hydrophilic lubrica-tion of the modified suface is inereasingly improvd. The optimum mass ratio poyvinyl pyrrolidineand Polyurethantirea is also found.
