As literatures illustrated , chemical functionalization is an effective route to strengthen the interface via covalent bonding. Among which silanization could introduce functional moieties like ethylene, amine, epoxy, thiohydroxy, etc., using silane coupling agents via amidation or esterification reaction, which have been applied in both nanocomposites and hybrid composites . Lee et al. utilized silane-functionalized GO to reinforce an epoxy adhesive, which improved bonding strength of lap joint bonded carbon/epoxy composites. Khan et al. functionalized GNPs through oxidation followed by silanization, and then dispersed the fillers into the matrix to reinforce CFRP composites, and resulted with improved ILSS, tensile and flexural strength, owing to the covalent bonds formed between the interfaces. We have previously applied two types of silane coupling agents to GO for aminoand epoxy-functionalization respectively, where the former one contributed more to the strength and stiffness, indicating a better interfacial stress transfer in the GO/epoxy nanocomposites .
