Polymers of Intrinsic Microporosity (PIM)-Based Membranes for Gas Separation

Abstract

Membrane based technology possesses potential market for gas separation due to its environmental friendliness, low cost, systemic simplicity and space saving features. Nevertheless, the polymeric membranes available in the market reveal a relatively low permeability and acceptable selectivity. These membrane materials are generally constrained by the Robeson trade-off between permeability and selectivity. Hence, to conquer the Robeson upper bound limit, this research study has been focused on the investigation and development of next-generation high performance polymeric membranes for CO2/CH4, CO2/N2, O2/N2 and H2/CO2 separations. Specifically, this research study focuses on four aspects including the Hence, to conquer the Robeson upper bound limit, this research study has been focused on the investigation and development of next-generation high performance polymeric membranes for CO2/CH4, CO2/N2, O2/N2 and H2/CO2 separations. Specifically, this research study focuses on four aspects including the (1) fabrication of polymer blend membranes with enhanced gas separation properties, (2) development of diamine modified membranes for H2/CO2 separation, (3) fabrication of polymer blend membranes with improved plasticization effects and (4) production of hollow fiber membranes for CO2/CH4 and O2/N2 separation.
