Abstract
Introduction: Conductive polymer composites (CPCs) have been getting attention in academic and industrial fields for several decades. Unfortunately, ordinary CPCs with random conductive network usually require a high filler percentage to provide desired conductivity. In upcoming research, an electrically conductive polymer composites with segregated structure was used in order to achieve high conductivity at low filler percentages
Methods: Segregated Structure HDPE/CNT nanocomposite were produced with pure nanotubes reinforcement and modified surface nanotubes by dry mixing method.
Findings: Microscopic images results showed that in both types of pure and surface modified composites an aggregated arrangement structure was created and carbon nanotubes were placed in interface between the granules. Conductivity results showed an exponentially increase in structure conductivity with increasing carbon nanotube content. The maximum value of conductivity in two composites with pure nanotubes and surface modified nanotubes at 6 wt% respectively was 47.675 , 27.675 s/m. The Maximum shielding (EMI) in raw carbon nanotubes reinforced composite and modified surface respectively was equal to 9 and 9.31 dB.
