The use of graphite oxide powder

graphite oxide powder as an antimicrobial to restore the application materials, including nano-specific reduction of graphene oxide suspension or reduction of graphene nano-oxide film as an antibacterial material applications. Reduction described in nano-graphene oxide suspension, including the preparation of pre-oxidation of graphite, pre-oxidation products of the separation, re-oxidation, oxidation products of the purification, the reduction of oxidation products. Reduction described in nano-graphene oxide film is the use of the 0.22μm PVDF membrane filtration as described in the nano-graphene oxide suspension to restore the system. Use of the invention of nano-graphene oxide as an antimicrobial to restore the application materials can be nano-graphene oxide as an additive reduction is made with antimicrobial properties of antibacterial coating made ​​of a product or material, used in medical and daily life.Dispersed in organic solvents, oxidation behavior graphène different effects. Such as oxidized graphite manufacturing, N-méthyl-2-pyrrolidone N-diméthylformamide dispersed, tétrahydrofurane, built with ethylene glycol,. In all these solvents, ozone layer, the cornea is divided into different materials, graphite oxide, an oxide film layer graphène Group has been achieved. Scattered between the leaves graphène oxidation www.gammachina.cn and nanomètres hundreds of long-term stability and large, micron similar graphène oxide dispersed in water. ) These results must be easy to manipulate and handle the process with graphène materials with different environments.Based on the graphite oxide aperture adjustable nano porous materials preparation methods, to natural flake graphite as raw material, strong sulfuric acid and sodium nitrate for intercalated agent and potassium permanganate as the oxidant of the thermal and chemical intercalated processing; Then will get flake graphite oxide to ion solution after the freeze-drying get flake graphite oxide powder, or use of polarity of the organic solvent to flake graphite oxide to ion solution for solvent for flake graphite oxide organic solvent suspension; , then use direct modification method and construct the supramolecular method of flake graphite oxide powder or flake graphite oxide organic solvent in modified suspension, get flake graphite oxide based on the pore diameter of adjustable nano porous materials; The party of the nano porous materials legal system through covalent bond or metal coordination key connection building, pore structure stability, the use of the modifying molecule range, can be in a wide range of adjust its pore size.
