Abstract

This study is about the fabrication and characterization of polyacrylonitrile (PAN) with conductive particles. Most of the research about the electrospinning of nanofibers were using basic well-known polymer such as PAN precursor to fabricate nanofibers. In fact, the addition of conductive particles as filler in the polymer may enhance the properties of the electrospun nanofibers to form composite fibers. In this case, there were two objectives needed to be achieved in this study which are to fabricate the electrospun nanofibers of PAN with conductive particle which was multi-walled carbon nanotube (MWCNT) and to investigate the characteristics of the electrospun nanofibers. The three main characteristics of the PAN/CNT electrospun nanofibers that have been investigated in this study were the chemical characterization, the conductivity and the morphology of the nanofibers. The fabrication of the nanofibers were done by utilizing electrospinning machine with the constant value of applied voltage, distance between needle jet and collector, and flow rate while the concentration of MWCNT in PAN/CNT solution was varied which were 0.00wt%, 0.03wt%, 0.05wt%,0.07wt% and 0.10wt%. The characteristics of the nanofibers were investigated by using FTIR, four point probe and scanning electron microscope (SEM) machine. The results showed that the presence of conductive particles (MWCNT) had improved the molecule chain structure of PAN/CNT nanofibers in chemical characterization. Hence, it also had enhanced the conductivity of nanofibers with the increased in the concentration of MWCNT in PAN/CNT. Furthermore, the fiber diameter of PAN/CNT nanofibers was increased as the concentration of MWCNT increased while the fiber diameter of PAN/CNT became smaller as undergo heat treatment in stabilization and carbonization process.
