Fabrication and study of structural, optical and electrical properties of UV curable conductive polyurethane acrylate films containing polyaniline-Co3O4 nanocomposites

In this research, Novel UV curable conductive nanocomposites containing urethane acrylate and PANi-Co3O4 nanocomposite have been prepared. At first, PANi- Co3O4 nanocomposites have been synthesized and then PUA-PANi-Co3O4 nanocomposites films were prepared by ultraviolet radiation. UV-Vis and FT-IR studies confirm that there was strong chemical interaction between PANi and Co3O4 nanoparticles, which caused the shifting of UV and FT-IR characteristic bands. The morphological studies of the PANi-Co3O4 nanocomposites showed uniform distribution of Co3O4 nanoparticles in PANi matrix, also SEM images of the PUA-PANi-Co3O4 nanocomposites films indicated distribution PANi- Co3O4 nanocomposites in PUA matrix. Electrical conductivity measurements of PANi-Co3O4 nanocomposites revealed that the conductivity of PANi decreased with adding content of Co3O4 NPs, also the conductivity of PUA increased with adding content of PANi-Co3O4 nanocomposites.
