Abstract: An in-situ strategy for the preparation of reduced graphene oxide/sodium calcium silicon (rGO/SLS) glass bulk composites using 3-aminopropyltriethoxysilane as a surfactant was reported. GO nanosheets that were negatively charged in an aqueous solution were combined with positively charged glass particles modified by amino groups through electrostatic self-assembly to generate composite particles. Through high temperature vacuum hot press sintering, GO was reduced to rGO, and rGO/SLS bulk composites were in situ produced. Results show that rGO is evenly distributed in the glass matrix and greatly enhances the mechanical properties of rGO/SLS bulk composites. With a 0.5% (mass fraction), addition of rGO in the rGO/SLS bulk composite, the flexural strength of the composite is about double that of pure SLS glass.
