Abstract
The effects of amine functionalized multi-walled carbon nanotubes (MWCNT) on morphological, thermal, mechanical, and electrical properties of an epoxy based nanocomposite system were investigated. Chemical functionalization of MWCNT by aminofunctionalization (MWCNT-NH2) were confirmed by FTIR, Raman spec, and TGA. Utilizing in-situ polymerization, a 1 wt% loading of MWCNT was used to prepare epoxybased nanocomposites. Chemical functionalization improves dispersion, processing, and compatibility of MWCNT when blended in an epoxy matrix leading to a possible increase in concentration of cross linking which dramatically increases the strength and modulus of the composite. Compared to the neat, nanocomposites prepared with MWCNT- NH2, showed a 58% and 37% increase in strength and modulus, respectively. SEM analysis of the fracture surface of the composites confirmed an improvement in dispersion. The paper will discuss the details of Processing, characterization and mechanical property evaluation.
