UV-reduction Of Graphene Oxide And Its Application

Graphene becomes a hot focus in the scientific community due to itstwo-dimensional structure. However, the compatibility of graphene and other polymer isvery poor, because of the structre of graphene does not contain any polar group. In thispaper, we used a simple method with UV radiation to prepare a water-soluble graphene.1. Study on GO reduction with UV irradiationUltraviolet light was used to reduce GO, and the impact of UV irradiation time onthe reduction effect was studied. In order to ensure that the RGO can be stable, we addedsodium dodecyl benzene sulfonate as surfactant in the solution. GO was characterized byUV, IR, Raman, X-ray diffraction etc, and this method was proved to be an effectivemethod to reduce the oxygen-containing groups of GO surface. RGO can be uniformlydispersed in water, and maintained a stable state over three weeks.2. Study on GO reduction with different amount of reductantThis paper studied the effects of GO reduction with different r amount of reductant,in order to study the reaction mechanism. The RGO’s output was improved with theamount of reducing agent increased, but it is also limited to a certain range. In thisreduction process, UV radiation can excite the water to make it produce electrons, andthis electrons can reduce GO. The reduction effect was related to generation rate and thenumber of electrons.3. Reinforce NR/SBR with grapheneIn this paper, the reinforcement effect of grapheme in NR/SBR was studied, andreinforcing effects was compared with acetylene black. We can find that: theperformance of NR/SBR with seven per graphene was equal to NR/SBR with fifty peracetylene black in resistance, tensile strength, hardness and tear strength.
