There are photosensitive polymers which undergo transformation (isomerization, ring closure, etc.) upon irradiation by UV light. Preliminary Japanese work indicated that the permeabilities of enzymes were reduced by a factor of ten when a polymer membrane was irradiated. This research will explore and extend the concept to gas separations, to cover eight commercially important gases and a number of photosensitive polymer membranes. The research will include preparation/characterization of membranes, permeability (solubility and diffusivity) measurements, and interpretation of the data by existing theories.

有一些光敏聚合物， （异构化、闭环等）在紫外线照射下 光 日本的初步研究表明， 酶的渗透性降低了十倍， 照射聚合物膜。 这项研究将探索 并将概念扩展到气体分离， 商业上重要的气体和一些光敏 聚合物膜 研究将包括 膜的制备/表征，渗透性 （溶解度和扩散率）测量和解释 根据现有的理论。
