由于薄膜材料表面的惰性特质影响了其更为广泛的应用，因此，研究如何改变薄膜表面特性而不影响其主体特性就显得尤为必要．文章采用大气压He／N2和He／O2辉光放电等离子体对双向拉伸聚丙烯（BOPP）薄膜进行表面改性．BOPP膜表面的亲水性和功能性在等离子体处理后得到了极大改善．重点研究了等离子体处理后的BOPP膜表面随存放时间的退化演变．研究结果表明：等离子体处理后的BOPP膜表面在存放时间内有疏水性恢复发生，然而，该BOPP膜表面的亲水性仍比等离子体未处理过的BOPP膜表面的亲水性要好得多；X射线光电子能谱仪检测到的等离子体处理过的BOPP膜表面的元素成分随存放时间也发生变化，表明薄膜表面的疏水性恢复可能是由于薄膜中的不稳定添加物从薄膜主体向表面扩散而导致的．而且由等离子体引起的薄膜表面的N元素相关功能团可能并不是高交叉链接的．

Since the inert nature of most polymer surfaces prevents wider applications of polymeric materials, it is desirable to develop a technology which can tailor surface properties without affecting their bulk property. At- mospheric He/N2 and He/O2 glow discharges are adopted to modify the surface of Biaxially Oriented Polypropyl- ene (BOPP) in this paper. It is proved that the hydrophilicity and functionality of BOPP surface can be signifi- cantly improved after plasma treatment. The degradation of plasma treated BOPP is particularly investigated a- long with the storage time. Hydrophobic recovery of plasma treated BOPP surface happens during the storage time. However, the hydrophilic property of BOPP surface is still much better than the plasma untreated ones. The element composition on BOPP surface, detected by X-ray photoelectron spectroscopy (XPS), varies with the storage time, which indicates that the hydrophobic recovery may be induced by the diffusion of mobile addi- tives from the polymer bulk to the surface and the plasma induced N-functional groups are not highly cross- linked.
