In this research, novel conductive nanocomposites containing urethane acrylate (UA) and
polyaniline/copper (II) oxide nanocomposites (PANi-CuO) were synthesized. At first
polyaniline/CuO nanocomposites with different amount of CuOnanoparticleswere prepared by
chemical oxidationpolymerization of aniline using ammonium peroxydisulfate as an oxidizing
agent. Afterward, UA-PANi-CuO nanocomposites were mixed and then cured by ultraviolet
irradiation. Analytical tests (FTIR and UV–vis spectroscopy, X-ray diffraction) approved chemical
structure of synthesized materials. The SEM images of the nanocomposites showed uniform
distribution of CuO nanoparticles in PANi matrix and UA-PANi-CuO in urethane acrylate matrix.
Electrical conductivity measurements of PANi-CuO nanocomposites revealed that the conductivity
of PANi decreased with adding content of CuO nanoparticles, also the conductivity of UA
increased with adding PANi-CuO.
