时/空分离光接枝技术是一种全新的光接枝方法.使用该方法可对不能直接光照到的表面进行改性。本文采用时/空分离光接枝技术对核孔膜的内、外表面进行接枝改性,实验结果表明,核孔膜外表面及孔内表面均能得到改善,并对反应机理进行了探讨。
Photo-initiated grafting separated by time and space is shown to be a novel photo-initiated grafting method, by which surfaces can be modified without UV irradiation. This paper describe how the photo-initiated grafting technique separated by time and space can be used to modify the surfaces inside and outside the holes of a track membrane. It was demonstrated that the properties of both the outer surfaces of the membrane and the inner surfaces of the hole were improved. The mechanism of the reaction is also discussed.
