Effect of polymer architecture on the gas separation performance of PIM-1 membranes
Abstract: Molecular simulations are used to demonstrate the effects of chain architectureson the gas separation performance of PIM-1 membranes. Four different architectures(linear, H-shape, star, and dendritic) were considered to investigate the transport propertiesof four industrially relevant gases (CO2, CH4, O2, and N2). The results obtainedfor the linear PIM-1 agree well with the available experimental data. The simulationsindicate that it is indeed possible to tune the free volume morphology of PIM-1 membranesby …
