In this work, Organic-inorganic composite membranes from sulfonated polyimide and zirconium sulfophenyl phosphate(ZrSPP)s were synthesized. A series of SPI blended with different ratio of ZrSPP were arranged and compared to each other.The sulfonated polyimides(SPI)s are synthesized from 1,4,5,8-naphthalenetetracarboxylic dianhydride(NTDA), 2, 2’-benzidinedisulfonic acid (BDSA) as the sulfonated diamine, and mixing the deca-methyl diamine(DMD). And zirconium sulfophenyl phosphate(ZrSPP)s are synthesized from zirconium oxychloride, phenyl phosphoric acid(PPOA). The synthesis of ZrSPP was confirmed by phosphate(P-O) stretchingbond, and pick is 900-1300㎝-1 in FT-IR. For the structure analysis, we were carried out FT-IR, XRD. |
