PVDF-PAn Co-polymer with High Permittivity Fabricated by Emulsion Polymerization
With employing dichloromethane as solvent, sodium dodecanesulphonate as surface active agent, ammonium persulphate as oxidizer, PAn was introduced into PVDF and co-polymer with high relative permittivity reaching to 280 was obtained by emulsion polymerization. By detecting the structural information and electrical property through FT-IR, XRD, SEM, informations about the co-polymers were presented and in this paper polymers with different electric properties were compared and analyzed. It was showed that the PVDF-PAn co-polymers had homogeneous properties in certain constitute range and as a result of emulsion, spherical PAn-PVDF media was fabricated. After robber mixing procedure at certain temperature, the PAn had a relatively average-fine dissolving in the PVDF, which overcame the difficulty of dissolving PAn on other substrate. This ensured the fine property for the matrix material in composites. With the increasing of the introduction quantity of PAn, the crystallization of the entire material complex had been raised greatly.
