Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
