Poly(cyclohexyl methacrylate)s (PCHMAs) were grafted on carbon nanotubes (CNTs) using surface-initiated polymerization technique. Electrical properties of the PCHMA-grafted CNTs (PCHMA-CNTs) were systematically measured under direct current (DC) and alternating current (AC), and compared with those of conventional nanocomposites prepared by blending PCHMA with CNT (PCHMA/CNT). At a comparable volume fraction of CNT, PCHMA-CNT is 15 orders of magnitude higher DC volume resistivity than PCHMA/CNT. This excellent electrical insulation of PCHMA-CNT is achieved by the perfect isolation of individual CNTs owing to the high molecular weight PCHMAs densely grafted on the CNTs. The highly insulated PCHMA-CNT showed the same AC frequency dependence of impedance as neat PCHMA. This means PCHMA-CNT is a dielectric. The dielectric performance of PCHMA-CNT was evaluated by comparing with that of a barium titanate-filled PCHMA composite.
