Properties of Polyacrylamide and Functional Multi-walled Carbon Nanotube Composite

Ayesha Kausar

Abstract


In this study we have investigated the structural and electrical properties of multi-walled carbon nanotube (MWCNT) reinforced polyacrylamide (PAM)-based composites. Two types of nanotubes were prepared and used i.e. acid functionalized MWCNT-COOH and amine-functionalized MWCNT-A. The nanocomposite was prepared using the solution cast technique. The samples were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), mechanical testing and electrical conductivity measurement. A comparative study has been made on the physical property of PAM/MWCNT-COOH and PAM/MWCNT-A nanocomposites. It was observed that the amine-functionalization of nanotube improved the filler dispersion into the polymer matrix. SEM photographs ascertain that the MWCNT-A nanoparticles were evenly dispersed in PAM matrix. The electrical conductivity of PAM/MWCNT-COOH was in the range of 0.03-0.5 Scm-1, while PAM/MWCNT-A had higher electrical conductivity of 0.4 to 1.2 Scm-1. The ultimate tensile strength of PAM/MWCNT-A nanocomposites was found to increase from 21-26 MPa, relative to PAM/MWCNT-COOH series (19-23 MPa).
