A type of functionalized graphene oxide (GO), named GO-POSS-BPA, was synthesized by nucleophilic substitution reaction with chloropropyl polyhedral oligomeric silsesquioxanes (POSS) and bisphenol A (BPA). Subsequently, the GO-POSS-BPA was added into bismaleimide-triazine (BT) resin to improve dielectric properties of bismaleimide-triazine resin. The structure of GO-POSS-BPA was characterized by Fourier-transform infrared spectra (FTIR), X-ray photoelectron spectroscopy (XPS), Xray diffraction (XRD) and transmission electron microscopic (TEM). The effects of GO-POSS-BPA on the dielectric, mechanical, thermal and water resistant properties of BT resin were investigated systematically. The results show that, GO-POSS-BPA decreased the dielectric constant and dielectric loss of BT resin over the testing frequency from 10 to 50 MHz, also enhanced the stability of dielectric constant. Meanwhile, the appropriate content of GO-POSS-BPA can enhance the impact and flexural strengths of BT resin to a certain extent. In addition, GO-POSS-BPA can also enhance the thermal stability and moisture resistance of BT resin.
