Pol(vinylidene fluoride) (PVDF) membranes that are hydrophobic 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-filling polymerization of PVDF membranes was performed using tetrabutylammonium 4-vinylbenzene sulfonate and a crosslinking agent. After polymerization, the counterion was removed from the membranes using a hydrochloric acid solution. The water uptake, dimensional stability, thermal stability, proton conductivity, and methanol permeability of the resulting membranes were measured using various techniques. The exoerimental results will be presented in detail. |
