The present work describes the development of polybenzoxazine (PBZ) nanocomposite with high dielectric constant using varying weight percentages of (0.5, 1.0, and 1.5 wt. %) benzoxazine functionalized MWCNT (CNT-BS) and benzoxazine through thermal ring opening polymerization. The dielectric constants are increased with increasing weight percentages of incorporation of CNT-BS, whereas dielectric losses are in the reverse trend. Data from Cyclic Voltammogram and impedance studies confirm the conducting behavior of CNT-BS/PBZ nanocomposites. The increase in the weight ratio of CNT-BS enhances the values of Tg and thermal stability. The uniform distribution of functionalized CNT-BS was ascertained from transmission electron microscope.
