Functionalized　graphene　oxide　(GO)　nanocomposites　including　GO-Fe　and　GO-Fe-P　were　prepared　and　used　as　a　curing　additive　for　a　one-component　room　temperature-curable　epoxy　adhesive　(OCRTCEA).　The　results　showed　that　the　functionalized　GO　nanocomposites　were　conducive　to　accelerating　the　curing　reaction　of　OCRTCEA　with　a　moisture-activated　ketimine　as　a　latent　curing　agent,　and　when　OCRTCEA　containing　1　wt%　GO-Fe-P　was　exposed　to　air　at　room　temperature　for　24　h,　its　lap　shear　strength　reached　11.2　MPa,　which　was　144%　higher　than　that　of　pure　OCRTCEA　under　the　same　test　conditions.　Furthermore,　the　storage　stability　of　OCRTCEA　containing　1　wt%　GO-Fe-P　was　similar　with　that　of　pure　OCRTCEA　over　60　days　of　storage.　The　enhanced　curing　reaction　activity　of　OCRTCEA　might　be　due　to　the　role　of　curing　accelerator　of　GO　nanocomposites,　the　enhanced　polarity　of　OCRTCEA　because　of　the　addition　of　GO　nanocomposites,　and　the　special　morphology　of　GO　nanocomposites.
