Robeson 2008 upper bound
WebAn upper bound for this measure will be given in Section 2. 2. UPPER BOUNDS FOR Ml(m, p) AND M2(m, p) The following upper bounds are obtained by using Minkowski's geometry of numbers. The first upper bound below also gives the estimate M1(m,p) < CEmEpl-1/?'(m) for any c > 0, where C, is as defined in Section 1. Theorem 3. If m and p are as ... Web[3] ROBESON L M.

WebBenchmarking PIM membranes in Robeson's upper bound plots 4,5 highlights their ultrahigh gas permeabilities compared with conventional polymer membranes; however, the gas selectivities of PIMs need to be improved. The relatively low gas selectivities of PIM membranes can be ascribed to the absence of well-defined microvoids, especially ultra ...

WebThe TO-HPI(0.37)-400-2 membrane possessed enhanced gas selectivities of 7.00 (H2/CO2) and 166.76 (H2/CH4) with a H2 permeability of 175.10 Barrer, surpassing the 2008 Robeson upper bound. As detected by in situ XRD, the thermal-oxidative cross-linking tightened the π–π stacking, which was beneficial for improving gas selectivity.
