【 摘 要 】

We report the effect of surface morphology on the conductivity of the poly-N-vinylcarbazole (PVK)/silica gel (SiO₂) nanocomposites as a function of SiO₂ weight percentage (%).The polymerization of PVK was initiated by a free-radical polymerization. The surface morphology of the prepared composite shows the incorporation of SiO2 in the prepared PVK-SiO₂ (PS) nanocomposites. The conductivity increased from 9.2 �? 10^?5 S cm^-1 to 9.6 �? 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%.
