生物无毒性高分子膜的紫外光透过性能研究

STUDY ON THE PENETRANCE OF ULTRAVIOLET LIGHT THROUGH POLYMERIC CEMBRANES

本文对ＰＶＡ、ＰＡＮ等几种高分子膜的紫外光透过性能进行了实验研究，为高分子膜在生物领域找到了新的应用，在选择透紫外光膜时，一方面要考虑高分子的分子结构，另一方面要考虑膜孔、膜厚等膜结构参数．

Penetrance of uItraviolet light through polymeric membranes of PVA,PAN and etc. isstudied using UV spectroscopy。The experiments find polymeric membranes a new application inbiological field.In chosing membranes through which UV light can easily penetrate,we should takethe rollowing two aspects into consideration:(1)the molecular structure of polymer;and(2)themembrane parameters including pore size,membrane thickness and so on.
