A simple and practical chemical cross-linking method has been demonstrated to make 6FDA-2,6-DAT asymmetric hollow fibers more resistant to plasticization by immersing them into a p-xylenediamine or m-xylenediamine/methanol solution for a short period of time at ambient temperature. FTIR spectra ...

We have studied the CO 2-induced plasticization phenomenon of asymmetric poly(2,6-toluene-2,2-bis(3,4-dicarboxyphenyl) hexafluoropropane diimide) (6FDA-2,6 DAT) hollow fiber membranes for CO 2/CH 4 applications. Several processing and thermal approaches have been investigated to study their ef...
We have studied the CO 2-induced plasticization phenomenon of asymmetric poly(2,6-toluene-2,2-bis(3,4-dicarboxyphenyl) hexafluoropropane diimide) (6FDA-2,6 DAT) hollow fiber membranes for CO 2/CH 4 applications. Several processing and thermal approaches have been investigated to study their ef...
By considering the degree of plasticization, dense-layer thickness, and heat treatment temperature, an optimal temperature of 250 掳C (for 5 min) is identified for the heat treatment of 6FDA-2,6 DAT hollow fiber membranes. NMR spectra suggest the cause of forming a highly densified skin after...
