Özet

A new substituted polyaniline/layered talc conductive composite material were synthesized chemically using ammonium persulfate as oxidizing agent in aqueous HCl medium. The oxidant type, N-ethyl aniline to oxidant mole ratio and N-ethyl aniline concentration on the PNEAn content and conductivity of the composite were investigated as the effect of the polymerization conditions. Optimum reaction conditions were outlined as NEAn/oxidant ratio I and 0.2 M NEAn monomer concentration with (NH4)2S2O 8 on the poly(N-ethyl aniline) yield and conductivity. The conductive composites were characterized by two probe technique for surface resistance and thermo gravimetric analysis (TGA) techniques. The increased thermal stability of the composite compared to that of pure polymer was obtained by the thermogravimetric analysis method.
