Abstract
A fluoropolymer blend with high ionic conductivity that can be applied in electroactive polymer composite includes following components: PVDF-g-SPS (styrene-grafted and sulfonated PVDF); PVDF; and hydrocarbon- or fluoro-elastomer. PVDF-g-PS(styrene-grafted PVDF) □ PVDF and hydrocarbon- or fluoro-elastomer are mixed with specific proportion and being dissolved in an aprotic solvent □ the solution is then cast film on a substrate followed by sulfonation to give the aforementioned compound membrane. The obtained compound membrane has excellent properties, such as thermal stability, acid-alkali resistance, good mechanical performance, excellent flexibility, and capability for processing appropriate cross-link for further enhancing the mechanical performance of this membrane.
