Abstract :

In this research, novel conductive nanocomposites containing urethane acrylate (UA) andpolyaniline/copper (II) oxide nanocomposites (PANi-CuO) were synthesized. At firstpolyaniline/CuO nanocomposites with different amount of CuOnanoparticleswere prepared bychemical oxidationpolymerization of aniline using ammonium peroxydisulfate as an oxidizingagent. Afterward, UA-PANi-CuO nanocomposites were mixed and then cured by ultravioletirradiation. Analytical tests (FTIR and UV–vis spectroscopy, X-ray diffraction) approved chemicalstructure of synthesized materials. The SEM images of the nanocomposites showed uniformdistribution of CuO nanoparticles in PANi matrix and UA-PANi-CuO in urethane acrylate matrix.Electrical conductivity measurements of PANi-CuO nanocomposites revealed that the conductivityof PANi decreased with adding content of CuO nanoparticles, also the conductivity of UAincreased with adding PANi-CuO.
