Studies on synthesis and property of novel acid-base proton exchange membranes

Department of Polymer Science and Materials, Dalian University of Technology, Dalian 116012, China

Received Date: 6 November 2006

Fund Project: This study was supported by the National Natural Science Foundation of China (No. 50373005) and the Chinese National Programs for High Technology Research and Development ("863" plan, No. 2003AA33G030).

Sulfonated poly (phthalazinone) s (SPPENK, SPPESK and SPPBEK) were prepared by direct polymerization reaction from sulfonated monomers. The novel acid-base membranes were composed of sulfonated polymers as the acidic compounds, and polyetherimide (PEI) as the basic compounds, casting from their N-methylpyrrolidone (NMP) solution directly onto clean glass plates at 60℃ aiming at enhancing membrane toughness and other relative properties. The resulted acid-base composite membranes had excellent resistance to swelling, thermo-stability, hydrolysis resistance and oxidative resistance properties with highly ion-exchange capacity (IEC).
