The changes in surface morphology and current-voltage characteristics of poly(p-phenylenevinylene)(PPV) thin film has been studied by varying the amount of incorporated SiO2 nanoparticles. The electronic structure of carbon atom in PPV and PPV/SiO2 nanocomposite films was studied by using near-edge X-ray absorption fine structure. The surface morphology of PPV/SiO2 nanocomposite film was found to be greatly dependent on the amount of incorporated SiO2 nanoparticles. The current-voltage behavior of PPV/SiO2 nanocomposite film was mainly dependent on the surface morphology of the film. The excess content of SiO2 nanoparticles in PPV/SiO2 nanocomposite film was revealed to induce an agglomeration of SiO2 nanoparticles where blocking of electronic conduction happens.
