Synthesis and characterization of metal-containing sulfonated polyimide membranes and their gas separation properties
We studied the synthesis and characterization of a thermally stable metal-containing in sulfonated polyimides (M-SPI) based on benzophenone tetracarboxylic dianhydride (BTDA), 4, 4’-diamino 2, 2’-biphenyl disulfonic acid (BDSA) and meta-phenylenediamine (mPDA). X-ray photoelectron spectroscop ...
