The origin of size-selective gas transport through polymers of intrinsic microporosity

An analysis of the diffusivity of light gases through Polymers of Intrinsic Microporosity (PIMs) shows that smaller H 2 and He gas molecules have a transport mechanism that is similar to that of porous materials, whereas larger gas molecules, CH 4 , N 2 , O 2 and CO 2 , show activated transport simi...
