Abstract

The intercrosslinking networks of unsaturated polyester (UP) toughened epoxy and amine modified multiwalled carbon nanotube hybrid nanocomposites have been developed. Ultrasonication and ball milling were carried out for effective dispersion of the amine functionalized multiwalled carbon nanotubes within the resin. A mixture of concentrated H2SO4/HNO3 was used to oxidize the carbon nanotubes and further chemical functionalization was carried out by using ethylene diamine. The pristine and amine functionalized nanotubes were examined by FT-IR, TGA, XRD and Raman spectroscopy to characterize the attached functional groups and the defects caused by the chemical modification. The epoxy resin was toughened with 5 and 10% (by wt) of unsaturated polyester using benzoyl peroxide as radical initiator and 4, 4'diaminodiphenylmethane (DDM) as curing agent. Epoxy and Unsaturated polyester toughened epoxy systems were further modified with 0.1, 0.3 and 0.5% (by wt) of amine modified multi walled carbon nanotube (NH2-CH2-CH2-NH-CO-MWCNT). The modified MWCNT filled hybrid UP-epoxy matrices developed in the form of casting were characterized for their mechanical, thermal properties and water absorption capacity as per ASTM standards. Thermal behavior of the matrices was characterized by differential scanning calorimetry (DSC) and thermo gravimetric analysis (TGA). Significant improvement in the flexural and tensile properties were observed on the neat epoxy and UP-epoxy blends according to the percentage content of amine modified MWCNT particles. The water absorption behavior decreases with UP toughening and increases with concentration of amine modified MWCNT on the epoxy and UP-epoxy matrix. The homogeneous morphologies of the UP toughened epoxy and UP toughened epoxy-nanocomposite hybrid systems were ascertained from scanning electron microscope (SEM).
