Paper Title:
Studies on Preparation and Properties of PVDF-g-PAMPS Membrane
  Abstract

A proton exchange membrane of poly (vinylidene fluoride) grafted onto poly (2-acrylamido-2-methylpropane sulfonic acid) (PVDF-g-PAMPS) was prepared as follows: acrylamido-2-methylpropane sulfonic acid (AMPS) was first added to a N-Methyl pyrrolidone (NMP) solution containing poly (vinylidene fluoride) (PVDF) that was modified with plain sodium silicate. Ammonium persulfate was then added as an evocating agent and PAMPS was directly grafted onto the PVDF that was modified with plain sodium silicate. The influences of AMPS contents on the proton conductivity and mechanical properties were studied. The results showed that AMPS is easily grafted into PVDF modified by Plain sodium silicate (Na4SiO4) and mechanical properties were improved, with increasing of the content of 2-acrylamido-2-methylpropane sulfonic acid, the proton conductivity of PVDF-g-PAMPS membranes was increased.
