“…On the contrary, Gospodinova et al 19 and others 20 -22 claimed successful dispersions using PVA due to efficient grafting of PVA on to the PANI particles. To overcome the problem of low adsorption of conventional stabilizers, Tadros et al 20 used tailor-made stabilizers-which could undergo graft copolymerization with ANI and thus get anchored on PANI particles to assist stable dispersion.…”

The aim of this workis to study the microstructure and D.C electrical conductivity of polyaniline-TiO 2 -poly-vinyl alcohol polymeric composite material synthesized by two methods. The first method of synthesis involved mixing of 40 wt% blendedpowders of polyaniline and TiO 2 micro particles in aqueous solution of PVA and the second method used 'in situ' deposition technique in which nano particle sized fine grade anatase TiO 2 powder (approximately 50 nm average particle size) was placed in the polymerization reaction mixture of aniline, which resulted in polyaniline being deposited on the surface of nano-TiO 2 particles forming a core-shell structure. 40 wt% of this composite polymer was then directly blendedwith aqueous solution of poly vinyl-alcohol, resulting in composite polymer of polyaniline-TiO2-poly-vinyl alcohol. The microstructural studies and electrical conductivity results shows that the second method of fabrication not only gives continuous fibrous structure to the conducting polymer without any agglomeration of TiO 2 , whereas in first method agglomeration of TiO2 results in conducting and non-conducting zone. It gives films with higher D.C electrical conductivity, in comparison to first method, which increases with increasing voltage.

Polyaniline-polyvinyl alcohol (PANI-PVA) interpenetrating network composite film is successfully prepared by in situ polymerization of aniline within PVA film embedded with different concentrations of potassium dichromate (K 2 Cr 2 O 7 ). The resulted composite is characterized by UV-Visible spectroscopy, SEM and XRD, TGA techniques and confirmed the formation of interpenetrating network formation of PANI within PVA matrix. Electrical conductivity of the composite films increase from 10 -6 to 10 -2 S/cm with the increase in the loading of dichromate from 10 -4 to 10 -2 M. Further, exposing in humidity environment, the conductivity of the composite films increases from 14 to 100% with the increase in humidity conditions from 11.3 to 84.3%.
