Özet
This study aims to optimize curing conditions and delays the curing time by mixing nanoparticles of different sizes and types in commercially available epoxy. To do this, the isothermal curing kinetics of epoxy containing TiO2, Al2O3, and graphene nanoplatelets (GNP) at variable ratios determined in the literature are investigated through differential scanning calorimetry (DSC). DSC measurements are then carried out to examine in detail the curing reactions of epoxy-TiO2, epoxy-Al2O3, and epoxy-GNP systems during isothermal curing. The Kamal-Sourour kinetic model best expresses the curing of the epoxy-nanoparticle systems for DSC. The lowest activation energies during curing for Al2O3, TiO2, and GNP are 21.88, 11.12, and 9 kJ/mol, respectively. The most suitable model for transition to a fully cured structure is observed in GNP.
