摘要：Novel graphene-oxide-reinforced silicone composites (GO Symbol of the Klingon Empire SC) are prepared by in situ polymerization of silanes and low concentrations (<0.15 wt%) of silylated GO (S Symbol of the Klingon Empire GO). After modification, the distances of the S Symbol of the Klingon Empire GO nanosheets are successfully increased from 0.72 to 0.87 nm. Compared with GO, the S Symbol of the Klingon Empire GO shows better dispersibility in organic solvents as well as remarkably enhanced decomposition temperature (T-d improved by 100 degrees C). After covalently grafting onto silicone resins via in situ polymerization, the obtained GO Symbol of the Klingon Empire SC exhibits greatly enhanced thermal stability (T-d up to 400 degrees C and T-g improved by 3-5 degrees C), increased storage modulus, loss modulus, and complex viscosity. The morphology, microstructure, interfacial adhesion of the developed GO Symbol of the Klingon Empire SC coatings were carefully investigated. The GO Symbol of the Klingon Empire SC coatings on metal exhibit good transparency (up to 90%), hydrophobicity, and excellent anticorrosion capability. This work provides a new strategy for developing high performance graphene-based silicone composite materials.
