The Preparation And The Property Of Graphene/Urushiol Polymer Composites

This article summarizes the history? basic structure? physicochemical properties of graphene and its preparation as well as modification and application, etc. From the principles of molecule design, we make urushiol compounds as a great modification agent and a reductant for graphene, and use it's reaction diversity to realized the controllable of graphene functionalization. The main content of my study is as follows:1) We used the facile reducibility and modification properties of urushiol, reducing graphene oxide to obtain urushiol modified graphene U-rGO. Then, U-rGO and hydrazine hydrate reduced graphene were used for preparation of two different urushiol composite films though the solution blended process. We further discussed the thermal stability, mechanical intensity, and chemical resistance and corrosion resistance properties of two different urushiol composite films. The results demonstrate that the U-rGO-urushiol composite film shows excellent thermo-stability, corrosion resistance, resistance against chemical media and physico-mechanical properties.2) We obtained the urushiol modified graphene load Fe3O4 nanoparticles (U-Fe3O4-rGO nanocomposites) through the one-pot solvothermal process, and applied it in dye and heavy metal ion wastewater treatment. The water treatment process was monitored by the UV-spectra. The results demonstrate that U-Fe3O4-rGO nanocomposites shows higher efficiency of RhB dye catalyzed degradation, dramatically increases the treatment efficiency and cyclic utilization rate of the other Fe3O4-rGO nanocomposites. Then we discussed the adsorption behavior of U-Fe3O4-rGO nanocomposties on Cr(?) in water, and the influencing factors like pH, ion species and temperature were studied. The results indicated that U-Fe3O4-rGO nanocomposites shows great efficiency adsorption of Cr(?), and the maximum equilibrium adsorption capacity is 158.9mg/g at 30?.3) In the sovlthermal process, we used urushiol as the reductant and modification to obtain the urushiol/graphene hydrogel, and ultimately obtain the urushiol/graphene aerogel after freeze-drying. Meanwhile, we preliminary studied on the role of urushiol in graphene aerogel formation process and its mechanism. We further observed the internal structure of graphene aerogel by SEM, and tested the physical mechanical properties of two graphene aerogel (with or without urushiol modification) by the universal electric material testing machine. The result shows that with the urushiol effection, the urushiol/graphene aerogel shows excellent mechanical properties and should have potential application on the field of wastewater treatment and energy storage.
