Structure and Morphology of PVDF-G-PAMPS Membrane

Article Preview

Abstract:

A proton exchange membrane of blended poly (acrylamido-2- methylpropane sulfonic acid) (PAMPS) grafted onto modified poly (vinylidene fluoride) (PVDF) membrane (PVDF-g-PAMPS) was prepared. Fourier transform infrared spectroscopy is used to characterize changes of the membrane's microstructures after grafting. The morphology of the membrane's microstructures after grafting is studied by scanning electrolytic microscope.The results show that 2-acrylamido-2-methylpropane sulfonic acid is easily grafted into PVDF modified by Plain sodium silicate (Na4SiO4).
