Abstract

The reactions of poly (vinylidene fluoride) (PVDF) film with some organic weak bases produce dehydrofluorinated product-polyfluorinated acetylene (PFA) on the two surfaces of the film. An orderly conjugated structure of the dehydrofluorinated film is suggested by IR and UV-VIS spectra. Inestigations by XPS, reaction depth and contact-angle hysteresis indicated that the two surfaces of PVDF film are the main reaction site. The conductivity of the dehydrofluorinated PVDF films are raised 5~6 magnitude of orders after doping by various dopants. The maximum value reaches 10^-^4s/cm. The doping behavior of the dehydrofluorinated PVDF film is different from that of polyacetylene.
