摘要:A chemical crosslinking protocol was developed to prepare carbon membranes from 3,3,4,4-oxydiphthalic dianhydride-4,4-oxydianiline (ODPA-ODA) type polyetherimide on the support of phenolic resin sheets. The effects of support pretreatment, membrane-coating methods and crosslinking protocols on the resultant carbon membranes were investigated. The microstructure, functional group evolution, thermal stability, mechanics, morphology, and gas separation performance of samples were characterized by XRD, FTIR, TGA, mechanical testing technique, and gas permeation technique, respectively. Results have shown that the chemical crosslinking is more beneficial than the popular thermal crosslinking protocol to fabricate supported carbon membranes for the advantage of simple preparation process. In addition, spin-coating is superior to drop-coating in terms of good membrane formation on the support. Under the preferred preparation conditions of crosslinker ethylene glycol usage at 10 wt % and spin-coating, supported carbon membranes can be obtained with good hydrogen separation performance.
