Effect of nano diamond on thermal behavior and thermal stability of epoxy resin

Epoxy thermoset resins have been used in the composite, construction, electronics, adhesive and coatings industries due to their good thermal, electrical and chemical properties. Distribution and dispersion of nanoparticles in polymer matrix is an important and influential issue in the mechanical properties of epoxy nanocomposites. Curing kinetics equations are used to evaluate and optimize the production process, and degradation kinetics modeling has become widely used as an essential tool for engineers to reduce costs and product quality. Addition of modified carboxyl and amine groups to pure epoxy resin does not change the curing reaction mechanism and also modifying the surface of nanodiamond increases the curing rate of epoxy nanocomposite. Investigation of hybrid thermal stability of epoxy nanocomposites in the presence of nanodiamonds and graphene oxide showed that the simultaneous presence of two different types of nano material can increase the thermal stability. In this research, the effect of adding nano diamonds and modified nano diamonds on morphology, mechanical and rheological properties, and modeling of curing kinetics and degradation kinetics and tribological properties have been investigated.
