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 - stacking, and the composite is found to improve greatly the dispersity of rGO in DMF and to be a good UV-absorber.
