摘要

In this paper, [ASiIM]Cl ionic liquid was successfully prepared from 1–3 aminopropylimidazole and 3-chloropropyltriethoxysilane. The dispersion system of [ASiIM]Cl ionic liquid and graphene in EP was studied. Ionic liquid-functionalized graphene IL@G was successfully prepared by an ultrasonic method. The structure and morphology of IL@G were characterized by FTIR, XPS, XRD, SEM, EDS and Raman spectroscopy, which proved that [ASiIM]Cl ionic liquid-modified graphene IL@G had been successfully prepared. IL@G was added to EP to study its effect on the thermal conductivity and mechanical properties of epoxy resin composites. The results showed that the tensile strength and impact strength of IL@G-modified EP composites were 13.7% and 143.7% higher than those of pure EP when the addition amount of IL@G was 3 wt.%. When the addition amount of IL@G was 5 wt.%, the thermal conductivity of IL@G-modified EP composites was 36.6% higher than that of pure EP materials. The good dispersion and compatibility of graphene IL@G modified by ionic liquid [ASiIM]Cl in EP matrix not only brought excellent mechanical properties to EP but also made EP have good thermal conductivity. This method provides a new idea for the application of epoxy resin composites in the field of high-performance materials.
