Abstract
It is important for gas permeable membranes, employed in many industrial applications, to have a high permeability as the cost of many processes such as gas separation and sensing directly depend on it. Polydimethylsiloxane (PDMS) has been a widely utilized polymer within permeable membranes as it possesses high intrinsic flux. However, little attention has been placed on the effect of crosslinking temperatures during synthesis. In this work, PDMS membranes were prepared using a range of crosslinking temperatures and evaluated for their gas permeation towards CO2, N2 and CH4. The investigation of the effect of the crosslinking temperature on gas permeation of PDMS membranes revealed an optim..
