摘　　要：采用磁控溅射法,以聚四氟乙烯(PTFE)为靶,氩气为载气,在再生纤维素膜表面沉积氟碳(FC)膜。用扫描电镜(SEM)、原子力显微镜(AFM)、红外光谱仪(FT-IR)和静态接触角测试仪对氟碳膜的表面形貌、表面结构和表面性能进行了研究,结果表明:随着溅射压力的增加,沉积的FC粒子数量增多,粒径变小,覆盖度增加;随着沉积时间的增加,FC膜逐渐变厚;FC膜由—CF3、—CF2—、—CF—和—C—4种组分组成。沉积FC膜后,再生纤维素膜实现了由亲水性向疏水性的转变。Regenerated cellulose films were modified by Ar plasmas in the presence of a magnetic field. We used PTFE as the target. The scanning electron microscope （SEM） and atomic force microscope （AFM） were employed to determine the morphology of the surface. The function parts of the surface were checked by FT-IR. And the contact angle was measured by the static contact angle testing apparatus. The experiment showed that the regenerated cellulose films were covered with FC film which consisted of four components：-CF3-, -CF2-,-CF- and -C-, and changed from hydrophilic to hydrophobic. Increasing with time, the FC film became thicker. Increasing with pressure, the number of FC grains increased and diameter decreased.
