▎ 摘　　要

In this study, graphene oxide (GO) was synthesized using modified Hummer's method and thence GO's surface was decorated with Pb3O4 and active functional groups. Thereafter, composites containing GO-Pb3O4 at diverse filler loadings were fabricated using vacuum shock technique. Successful synthesize of GO and GO-Pb3O4 were confirmed using FTIR, EDAX, SEM, and PSA analyses, while developed composites subjected to chemical resistance and dynamic mechanical thermal analysis analyses to examine their resistance against chemical degradation and thermo-mechanical performance, respectively. Achieved results showed that developed composites present fantastic resistance against solvents infiltration, chemical degradation, and crack propagation. Moreover, increase in the weight percentage of GO-Pb3O4 to 10 wt% can lead to 0.9 kgf/mm(2), 27.8 degrees, and 53.23 degrees C increase in the hardness, contact angle, and glass transition temperature compared with neat epoxy resin, respectively. This significant enhancement of developed composites is due to the strong interfacial connection and interaction between fillers and matrix.
