Supplement: The Use of Photopolymers to Provide Real Time Control of Gas Separation Membrane Properties

有些光敏聚合物在紫外光照射下发生转化（异构化、环闭合等）。日本的初步工作表明，当聚合物膜受到辐照时，酶的渗透性降低了十倍。这项研究将探索并扩展气体分离的概念，以涵盖八种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（溶解度和扩散性）测量，以及现有理论对数据的解释。

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.
