Abstract
α-Vanadyl phosphate , crystalline cerium phosphate and α-vanadyl phosphate- crystalline cerium phosphate nanocomposite, α-VOPO4.2.5H2O(VOP), Ce(HPO4)2.1.33H2O (CePc) and [VOPO4]0.33[Ce(HPO4)2]0.67.0.41 H2O,(VOP-CePc) , respectively, were prepared and characterized by XRD, TGA, FT-IR and SEM. [VOPO4]0.33 [Ce(HPO4)2]0.67 / polyaniline, polyindole, polycarbazole, polyaniline-co-polyindole, polyaniline-co-polycarbazole, polyindole-co-polycarbazole nanocomposites, were prepared and characterized by elemental (C,H,N) analysis, FT-IR and SEM. [VOPO4]0.33[Ce(HPO4)2]0.67.0.41H2O act as self-support polymerization of the monomers and the co- monomers, where part of VOP and CePc of the inorganic matrix is attacked by the monomers and the co-monomers respectively, converted to V(IV) and Ce(III).. From elemental (C, H, N) analysis, the amount of organic materials present in resultant novel [VOPO4]0.33 [Ce(HPO4)2]0.67./ polyaniline, polyindole and polycarbazole nanocomposites were PAni 20.71 % in wt,, ,PIn 5.99 % in wt, PCz 10.47, % in wt, respectively. The % in wt. of the resultant copolymers nanocomposites were ( PAni 8.96 % , PIn 11.32 % ), / (PAni 6.58 % , PCz 8.9 3%) , / (PIn 0.565% , PCz 5.227 % ). respectively. .Physico-chemical analysis and Color changes during process of polymerization support the formation of the resultant novel conducting polymers and co-polymers nanocomposites. The electrical conductivity measurements of the resultant polymers and co-polymers found to be in range of semiconductors
