摘　　要：A new s-triazine derivative modified graphene composite, in which 2,4,6-tri（2,4-dihydroxyphenyl）-1,3,5- triazine （TDTA） was attached onto reduced graphene oxide （rGO） via the noncovalent functionalization approach, named TDTA/rGO, was reported. And the TDTA was synthesized via a Friedel-Crafts reaction. FTIR and NMR spectroscopic characterizations were carried out to confirm the synthesis of TDTA. UV-Vis, XPS and TEM revealed that TDTA molecules were successfully loaded onto graphene sheets by π-π stacking, and the composite is found to improve greatly the dispersity ofrGO in DMF and to be a good UV-absorber.A new s-triazine derivative modified graphene composite, in which 2,4,6-tri（2,4-dihydroxyphenyl）-1,3,5- triazine （TDTA） was attached onto reduced graphene oxide （rGO） via the noncovalent functionalization approach, named TDTA/rGO, was reported.
