The electrically conducting nylon 6/poly(vinylalcohol) (PVA)/poly(p- pheylene)(PPP) composite films were synthesized by exposinig nylon 6/PVA blend films containing ferric chloride as an oxidant to benzene vapour and their electrical conductivity and morpholoy were studied. After benzene was polymerized in nylon 6/PVA blend films for 72 hours, the composite films showed the conductivity as high as 10-5 -10-2 s/cm and it increased with increasing the concentration of the oxidant, the content of PVA and polymerization time. The formation of PPP in nylon 6/PVA blend film was confirmed by FT- lR spectra and scanning electron micrographs. The X- ray diffraction curve of composite film showed that the structure of PPP in nylon 6/PVA blend film was amorphous.
