| titleOfInvention | Amphoteric two-dimensional nanosheet and preparation method and application thereof |
| abstract | The invention discloses an amphoteric two-dimensional nanosheet and a preparation method and application thereof, wherein the amphoteric two-dimensional nanosheet is prepared by the following steps: uniformly dispersing the few-layer graphite oxide in toluene, adding an alkylamine coupling agent for reaction, fully dispersing the prepared amino-terminated graphene oxide dispersion in a toluene-dimethylformamide mixed solvent, and adding alkyl glycidyl ether for reaction to obtain an amphoteric two-dimensional nanosheet; compared with emulsion composed of conventional surfactants, the amphoteric two-dimensional nanosheet disclosed by the invention can spontaneously form water-in-oil Pickering emulsion at an oil-water interface, effectively stabilize the water-flooding front edge, expand the swept volume of water flooding, is simple and convenient in synthesis process, convenient for large-scale production, has a wide application range, and can be widely applied to water-flooding oil reservoir development. |
