Title One Step Preparation of MTMS/Graphite Oxide Composite and Study on Oil Absorption Properties of Materials.
Abstract
In order to expand the application of graphene oxide in wastewater treatment and improve the absorption properties of oil, we use graphene oxide as basic material. The low density and oil absorbing material with high selectivity is compound with Methyl trimethoxysilane and Fe3O4, which has super hydrophobic properties. By X-ray diffraction, SEM, TEM, contact angle measurement and other methods for the characterization of materials, the silylated material retains good porosity. Fe3O4 nanoparticles were uniformly dispersed on graphene oxide. Compared with the traditional inorganic porous materials, graphene oxide silylated showing higher performance, proved to be very effective in the removal of water surface oil spill. The iron oxide gives this oil absorbent material magnetic, which is beneficial for the material to be recovered in the water spill incident.
