Abstract
Incorporation of photoresponsive moieties (phenylazobenzene) into a polymer (ethyl cellulose) has been shown to provide a method to reversibly modify the diffusivity of a non-porous membrane for gas separations. The diffusivity of N
2
decreased by up to 18% upon exposure to UV light. No changes were observed for the other gases in this study (Ar, He, H
2
, CO, CO
2
, and O
2
). The anomalous behavior of N
2
is explained in terms of an interaction between the N
2
and cisazobenzene.
