Effect of vulcanized elastomeric nanoparticles on thermal stability and the maximum decomposition temperatures of epoxy resin

In this study, the thermal stability and maximum degradation temperature of pure epoxy resin and the effect of ۰.۵, ۱ and ۱.۵% elastomeric nanoparticles on epoxy resin by thermal gravimetric analysis at different heating rates of ۱۰, ۱۵ and ۲۰ oc/min have been investigated. Evaluation of thermal degradation behavior of epoxy resins and nanocomposites showed that thermal degradation is single-stage. ۰.۵% nanocomposite increases thermal stability by increasing the heating rate and also reduces the rate of thermal degradation. with increasing heating rate, T۵۰ for epoxy resin and ۱% nanocomposite increased, and also for ۰.۵ and ۱.۵% nanocomposites initially increased, and then decreased . By adding elastomeric nanoparticles to the epoxy resin matrix, the amount of Tm nanocomposites increased.
