POLİANİLİN VE POLİ(VİNİL ASETAT) KULLANARAK İLETKEN KOMPOZİT FİLMLERİN HAZIRLANMASI VE KARAKTERİZASYONU

İletken polianilin/poli(vinil asetat) (PAn/PVAc) kompozit filmleri, undop PAn ve PVAc ın dimetilformamit (DMF)deki çözeltisinden elde edilen filmlerin dop edilmesi ile hazırlandı. Filmlerin iletkenliği PAn/PVAc kütle oranı60/40 olana kadar arttı ve daha yüksek PAn değerlerinde fazlaca değişmedi. Film iletkenliği üzerine, film kalınlığıve dop etme süresinin etkisi araştırıldı ve en yüksek elektriksel iletkenlik sulu 2.0 M HCl çözeltisinde 1 saat dop ileelde edildi. PAn/PVAc kompozit filmlerinin yüzey morfolojisi SEM ile incelendi, karakterizasyonları iletkenlikölçümleri, FTIR ve TGA teknikleri kullanılarak yapıldı.

THE PREPARATION AND CHARACTERIZATION OF CONDUCTIVE COMPOSITE FILMS OF POLYANILINE AND POLY(VINYL ACETATE)

Polyaniline/poly(vinyl acetate (undoped PAn/PVAc) composite films were prepared by doping of films obtained bycasting of the solution of undoped PAn and PVAc in dimethylformamide (DMF). The electrical conductivity offilms was increased up to 60/40 PAn/PVAc ratio and then level off. The change of the conductivity of films withfilm thickness and doping time was investigated. The maximum conductivity was obtained by doping of undopedfilms in aqueous 2.0 M HCl solution with one hour. Surface morphology of coductive PAn/PVAc composite filmswas examined by SEM techinique. The characterization of composite films was also performed by conductivitymeasurements, FTIR and TGA techniques.
