Effect of UFNBR on the Chemoviscosity of Epoxy Resin

This study, the focus was on investigating the viscosity of epoxy resin ML۱۰۱ and hardener HA۹۴when combined with elastomeric nanoparticles at various concentrations (۰, ۰.۱, ۱, and ۱.۱ by weight).Rheometry was used to measure viscosity at three different temperatures (۴۱۶C, °۰۶C, and °۱۶C)under isothermal conditions. The results showed that the addition of elastomeric nanoparticles toepoxy resin at a constant temperature led to reduced transition times in complex viscosity, which wasattributed to the interaction between the epoxy resin and elastomeric nanoparticles. Specifically, at°۰۶C, samples containing ۱۱ and ۰.۱۱ nano composites exhibited similar complex viscosity behavior,showing a decrease compared to other samples. By applying the Arrhenius viscosity model tocalculate activation energy, it was noticed that the inclusion of elastomeric nanoparticles in epoxyresin decreased the activation energy, with the ۱۱ nano composite sample displaying the lowestactivation energy value.
