dc.description.abstractThis thesis advances the field of conductive filler/polymer composites (CPCs) by providing insight to this critical question: what is the significance of polymer/filler interaction on morphology and electrical properties of CPCs? Carbon nanotubes (CNTs) as conductive filler and two immiscible polymers, i.e. polystyrene (PS) and polyamide 6 (PA6), as matrix were melt blended with different compositions. The generated blends were investigated morphologically via light transmission, scanning electron, and transmission electron microscopy techniques; and electrically including DC conductivity, EMI shielding, imaginary permittivity and current-voltage characteristic. It was found that high interaction between PA6 and CNT led to excellent dispersion state, but hindered conductive network formation; while in more agglomerated PS/CNT composites, CNTs percolated much more readily. In PS/PA6/CNT blends, CNTs were selectively localized in PA6 phase. Though CNT-rich phase was not co-continuous, percolation still occurred, and higher electrical conduction was obtained.en_US
