Chemical cross-linking modifications of polymeric membranes for gas separation applications
In the last two decades, various engineered glassy polymers have been developed with both experimental and commercial values. These materials combine high selective with acceptable permeability coefficients and therefore, are suitable for the preparation of gas separation membranes (Barsema et al. 2...

| தொகà¯à®ªà¯à®ªà¯: | In the last two decades, various engineered glassy polymers have been developed with both experimental and commercial values. These materials combine high selective with acceptable permeability coefficients and therefore, are suitable for the preparation of gas separation membranes (Barsema et al. 2003). The glassy state offers a more structure sieving matrix than a rubbery state, as well as higher load-bearing properties, allowing high pressure drop across the membrane. Thus, the separation of common gas pairs is accomplish by diffusion control or size selective sieving mechanisms (Robeson). |
