Functionalized graphene oxide (GO) was successfully modified by grafting 1,3,5-triglycidylisocyanurate (TGIC) onto the surface of GO. The modified GO was then added to a novolac epoxy composite at various volume fractions to improve the interfacial compatibility between the filler and matrix. Samples of the modified GO/novolac epoxy composite were fabricated through the hot-pressing method.Microstructural analysis revealed that the modified GO dispersed well in the matrix and formed thermal conductive pathways across the matrix. The thermal degradation temperature of 50% weight loss of the modified GO/novolac epoxy composite was 166 C higher than that of the novolac epoxy. The data for loss factor tan d demonstrated that when the composite contained 36.8 wt% of modified GO, the glass transition temperature of the modified GO/novolac epoxy composite was 222 C, which is 90 C higher than that of the novolac epoxy. The thermal conductivity of the modified GO/novolac epoxy composite. Results indicated that the incorporation of surface-modified GO into the novolac epoxy positively affects the thermal conductivity and various properties of the modified GO/novolac epoxy composite.

“…It has been shown that the good solubility of graphene oxide (GO) in organic solvents can significantly improve its dispersity in composites . The integration of GO has been used for reinforcing the thermomechanical stability of PDCs . It has also been shown that the integration of GO can significantly improve the toughness and strength of SiC and Si 3 N 4 ceramics …”

We report the synthesis of silicon oxycarbonitride ceramic‐graphene oxide (SiCNO–GO) composites by using polyvinylsilazne (PVSZ) and GO as precursors through cross‐linking processes, in which GO organizes into microspheres in the SiCNO matrix. The formation of GO microspheres significantly enhances the electrical conductivity of SiCNO. The electrical resistivity of SiCNO–GO composites shows a negative temperature coefficient in the range from 25°C to 600°C. We demonstrate the application of SiCNO–GO composites as the functional component of high‐temperature sensors.

“…This is because that the test temperature under the experimental conditions of cone calorimeter test of 35 kW/m 2 is much lower than the final residual carbon temperature of 900°C in the TG test; and there is an ignition source in the cone calorimetry experiment; however, there is no combustion in the TG experiment. The results were consistent with the previous literature research …”

In this study, two types of carbon fiber reinforced polymer (CFRP) flame retardant composites, CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW (EG, GF, and MW are the acronyms of expandable graphite, glass fiber and mineral wool, respectively), were prepared via compression molding, with expandable graphite‐based mat incorporated at the surface of the CFRP. The results showed that compared with the control CFRP, both CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW passed vertical burner test and 45° burner test according to FAR25.853. Moreover, the limiting oxygen index (LOI) values of both CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW were increased, and the peak of heat release rate (PHRR) and total heat release (THR) were reduced. Besides, CFRP@MatEG‐GF‐MW had higher flame retardancy than CFRP@MatEG‐GF. This was attributed to the formation of a more stable and dense carbon layer structure. The mechanical test results showed that the tensile strength of CFRP@MatEG‐GF‐MW was higher than that of CFRP@MatEG‐GF. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47801.
