摘　　要：目的:利用低温等离子体轰击法建立高分子聚合体表面润湿性研究模型。方法:使用氧低温等离子体轰击六甲基二硅氧烷薄膜聚合体表面,测定表面接触角,建立轰击时间-表面接触角曲线,建立线型回归方程。观察在不同介质中保存时材料表面接触角的变化情况。结果:经过氧等离子体轰击后,六甲基二硅氧烷薄膜聚合体表面接触角明显下降,与处理时间呈现负相关性。在空气中保存时,表面接触角随时间逐渐上升,0度接触角表面24 h后上升为20°左右,而在双蒸水中保存的表面接触角基本保持不变。结论:氧等离子体轰击法能可控性地改变六甲基二硅氧烷薄膜聚合体表面润湿性,处理后的表面在水中接触角保持稳定,该方法可以用来建立表面润湿性研究模型。AIM： To establish a model of polymer surfac, e wettability by oxygen plasma treatment. METHODS： Hexamethyldisiloxane（HMDSO） polymer fihns were treated by oxygen plasma. The contact angle of the surfaces was measured, then the treatment time - suface contact angle curve was setup. Change of the surface contact angle with time was observed in different conservative conditions. RESULTS： The contact angle of HMDSO surface decreased gradually with the increasing duration of the plasma treatment. Surface contact angle increased with time when the specimen was preserved in air and it was stable when in distilled water. CONCLUSION： A stable surface wettability model can be setup by plasma treatment on hexamethyldisiloxane polymer film.
