Abstract
Effects of various functionalized multi-walled carbon nanotubes (MWCNT) on cure kinetics and flexural properties of an epoxy based nanocomposite system were investigated. Chemical functionalization of MWCNT by oxidation (MWCNT-COOH), direct-fluorination (MWCNT-F) was confirmed by FTIR, and Raman spectroscopy. One weight percentage loading of MWCNT was used to prepare epoxy-based nanocomposites through in-situ polymerization. Curing kinetics showed that MWCNT-COOH and MWCNT-F would catalyze the curing process altering activation energy, enthalpy of reaction, and reaction rate. Compared to neat resin, nanocomposites fabricated with MWCNT-COOH and MWCNT-F showed a 48%, and 33% increases in flexural strengths, and 55% and 16% increases in flexural moduli, respectively. SEM analysis of the fracture surface of the composites confirmed an improvement in dispersion.
