Processing and characterization of epoxy resin dispersed with multi walled carbon nanotube (MWNT) derived from camphor

In the present study, multi walled carbon nanotubes (MWNTs) derived from camphor were dispersed in EPON 862 resin via sonication. Effectiveness of MWNT addition on the mechanical properties of EPON 862 resin was evaluated by performing tension test and dynamic mechanical analysis. While tensile strength remained almost unchanged with the addition of up to 0.15 wt.% MWNT, there was an appreciable change in the elastic modulus and dynamic mechanical properties such as storage modulus, loss modulus and tan δ.

► EPON 862 MWNT nanocomposite was fabricated by dispersing MWNT via sonication. ► Addition of MWNT has a positive impact on the glass transition temperature, tensile as well as the thermomechanical behavior of EPON 862 resin. ► The findings of the present investigation could prove vital in the development of epoxy based composites which are more eco-friendly [6].
