Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The silica nanoparticles functionalized with poly(butyl acrylate‐<italic>co</italic>‐glycidyl methacrylate)‐<italic>g</italic>‐diaminodiphenyl sulfone (P(BA‐<italic>co</italic>‐GMA)‐<italic>g</italic>‐DDS)) were prepared via atom transfer radical polymerization and ring open reaction, and characterized by Fourier transform infrared and X‐ray photoelectron spectroscopy. Subsequently, the influence of SiO₂ content on the mechanical and thermal properties for the bismaleimide (BMI) resin nanocomposites modified with pristine SiO₂ and SiO₂‐P(BA‐<italic>co</italic>‐GMA)‐<italic>g</italic>‐DDS) was investigated. It was found that SiO₂‐P(BA‐<italic>co</italic>‐GMA)‐<italic>g</italic>‐DDS) was more effective as a modifier than pristine SiO₂. The most significant improvement of the impact strength (+108.7%) and flexural strength (+64.5%) was obtained with SiO₂‐P(BA‐<italic>co</italic>‐GMA)‐<italic>g</italic>‐DDS) at 0.5 wt% content. Moreover, the thermal properties of nanocomposites were distinctly improved with the addition of functionalized SiO₂. The reasons for these changes were discussed in this article. POLYM.
