Abstract

This paper used a new approach of preparing poly-composites by covalent linkage between the MWCNT’s by imine group. The Poly (Imine)/MWCNT Composite was synthesized by the solution blending method from reacted amino multi-walled carbon nanotubes (MWCNT-NH2) with Terephthalaldehyde (TPAL). The obtained poly-composite was characterized by FT-IR, UV-Vis, XRD, TEM, SEM, TGA, DSC and DC electrical conductivity. The formation of Poly (Imine)/MWCNT composite was confirmed. The DC electrical conductivity of poly-composites was within the range 2.3 × 10–4 - 5.3 × 10–4 S/cm due to the interaction between the nanotubes.

Summary

Introduction

Nanotechnology opens up a new perspective to shape new generations of composites structures. CNTs can be conductors like metals or semiconductors: they can transport electrons over long distances without significant interruption that makes them more effective than copper [12] [13]. This unique combination of mechanical and electrical properties makes CNTs an ideal reinforcing agent for many materials and products including polymers [14] [15]. There are no studies performed in detail with the aim of comparing the effect of carbon nanotubes with imine functional groups on poly-composites. A new approach of poly-composites by covalent linkage between the MWCNT’s by imine group was synthesized
