摘要：
The nano-Al2O3/polyether sulfone-epoxy resin (EP/5PES/1Al2O3) composites were fabricated and the effects of different nano-Al2O3 and PES addition on the mechanical, dielectric and thermal stability properties of composite were also investigated. The results shows that the tensile strength, elongation at break and impact strength of EP/5PES/1Al2O3 composite arrive at 58 MPa, 13% and 16.2 kJ/m2, respectively, which increase by 61.1%, 20.3% and 8.0% compared to the pure epoxy resin. Additio-nally, the EP/5PES/1Al2O3 composite show higher dielectric constant and dielectric loss of 7.6 and 0.016 (100 Hz) compared with the pure epoxy resin. The thermogravimetric analysis (TG) results shows that the thermal stability of EP/5PES/1Al2O3 composites has been improved and its initial decomposition temperature is improved to 358℃, which is 14℃ higher than that of the pure epoxy resin, indicating a great improvement to thermal stability of composites. © 2017, Materials Review Magazine.
