Rehman, Sheikh published the artcileDevelopment of new graphene/epoxy nanocomposites and study of cure kinetics, thermal and mechanical properties, Recommanded Product: 4,4-Diaminodicyclohexyl methane, the publication is Thermochimica Acta (2020), 178785, database is CAplus.
New graphene/polymer nanocomposites were prepared using graphene nanoplatelets (GNPs) and the epoxy system Epilok 60-566/Curamine 32-494. The GNPs were first dispersed into the curamine hardener using bath ultrasonication, followed by the addition of the epoxy resin. The cure kinetics were studied by DSC under non-isothermal and under isothermal conditions. The kinetic parameters of the curing process were determined using the non-isothermal Kissinger and Ozawa-Flynn-Wall models. The degree of curing increased with the addition of GNPs, while the activation energy decreased by 13.7% for the primary amine reaction and by 6.6% for the secondary amine reaction with epoxy groups as obtained from Kissinger. An increase in thermal stability by the addition of GNPs was identified in the range of 360-580° using TGA. In terms of mech. properties, addition of an optimum amount of 0.5% weight of GNPs in the hardener improved the Young’s Modulus by 37%. Nanoindentation measurements showed 9.4% improvement in hardness at 0.7% weight
