“…Olmos et al studied the thermo-mechanical properties of polysulfone filled with nanosilica particles, and found that the mechanical properties remain almost constant up to a relatively high loading (i.e., 5 wt.%) of nano-silica such as flexural strength and hardness [8]. Li et al investigated the effect of nanoparticles of hyperbranched polyester and zirconium slag on impact toughness of epoxy matrix, and confirmed the toughening mechanisms which were induced by plastic deformation, inorganic nanoparticles and phase separation [9].…”

“…44 Our previous report demonstrated that an incorporation of 16 wt% HBPH could improve the impact strength by ;32.8% but decrease the flexural strength of the epoxy resins. 36 To improve the epoxy thermoset strength, some rigid phases should be incorporated into epoxy resins, such as nanoparticles, carbon tubes, or CSPs, which were mentioned above. In this work, a new type of CSP that consists of HBPE and silica nanoparticles was chosen as a good solution.…”

A novel core-shell particle that consists of epoxide-terminated hyperbranched polymer (HBP) and silica nanoparticles was incorporated into an epoxy/hydroxyl-terminated HBP blend to fabricate a high-performance epoxy thermoset. The effect of the core-shell particle content on the mechanical properties of the epoxy thermosets was investigated in detail. Results from tensile, flexural, and impact tests are provided. The impact fracture surface was studied by field emission-scanning electron microscopy. The incorporation of 2 wt% core-shell particles improved the tensile strength, percent elongation at break, flexural strength, and impact resistance of epoxy/hydroxyl-terminated HBP thermosets. Field emission-scanning electron micrographs showed that core-shell particle addition resulted in large-scale shear deformation and debonding from the epoxy matrix, and improved the epoxy resin toughness.

“…Recently, we reported a hydroxyl group terminal HBP synthesized through a polymerization of AB 2 approach with succinic anhydride and diethanolamine that could favorably improve impact resistance of DGEBA epoxy resin thermosets [50]. Herein, we reported a simplified strategy to synthesize an amino-terminated hyperbranched polymer from diethylenetriamine and methyl acrylate by melt polycondensation.…”

Amino-terminated hyperbranched polymer (HBP-NH 2 ) was synthesized from diethylenetriamine (DETA) and methyl acrylate (MA) by melt polycondensation through AB 3 and AB 2 route, and its chemical structure was characterized by attenuated total internal reflectance infrared spectroscopy (ATR-IR) and 1 H nuclear magnetic resonance ( 1 H-NMR) spectroscopy. Then, the influence of HBP-NH 2 content on the toughness improvement and fractural surface morphology of diglycidyl ether of bisphenol A (DGEBA) cured systems was investigated through impact resistance test and field emission scanning electron microscopy (FESEM), respectively. The results indicated that HBP-NH 2 can enhance the toughness of epoxy cured system near 61 % than the neat DGEBA cured thermosets. FESEM images show that the toughness enhancement of epoxy system should be based on shearing deformation mechanism (the thermosets modified with low content of HBP-NH 2 ) and the second phase toughening mechanism (the thermosets modified with high content of HBP-NH 2 ).
