Poly(vinylidene fluoride) (PVDF) membranes have been extensively employed for water treatments since they have high void volumes and well-defined porosity as well as excellent chemically inert property. In this study, pore-filled PVDF membranes containing crosslinked sulfonated polystyrene were prepered using tetrabutylammonium 4-vinylbenzene sulfonate and a crosslinking agent. After polymerization, the counterion (tetrabutylammonium) was removed from the membranes using a hydrochloric acid solution. The resulting pore-filled PVDF membranes were characterized with respect to water uptake, dimensional stability, thermal stability, ion exchange capacity, mechanical property, proton conductivity using various techniques. The experimental results will be presented in detail. |
