We report the effect of surface morphology on the conductivity of the poly-N-vinylcarbazole (PVK)/silica gel (SiO(2)) nanocomposites as a function of SiO(2) weight percentage (%). The polymerization of PVK was initiated by a free-radical polymerization. The surface morphology of the prepared composite shows the incorporation Of SiO(2) in the prepared PVK-SiO(2) (PS) nanocomposites. The conductivity increased from 9.2 x 10(-5) S cm(-1) to 9.6 x 10(-4) S cm(-1) with the increase in the percentage of clay from 5 to 30%. The nanocomposites show a percolation behavior having a threshold value between 15 and 20%.
