To fully utilize intrinsic properties of carbon nanotubes (CNT) for the industrial application, preservation of the quality is of importance through dispersion processes in matrices. We demonstrated a 104-fold enhanced electrical conductivity of CNT rubber composite keeping the CNT quality by the predispersion of CNT powder in the viscous rubber base compound. Furthermore we found that higher viscosity solvents can more efficiently unravel CNT powders with slighter decreases of the CNT quality. Our method can refrain from long, heavy, conventional dispersions, and be widely applied to CNT industries.
