▎ 摘  要

NOVELTY - Preparing high flux anti-penetrant film taking oxidized graphite alkene acyl chloride derivative product involves preparing 0.1-0.3g/L graphene oxide and 0.1-lg/L thionyl chloride of the modifying agent in isoparaffin solvent, mixing them uniformly, distilling off the thionyl chloride at -0.1mega pascals to -0.03mega pascals ay 50-80 degrees C to obtain a graphene oxide chlorination product. The obtained graphene oxide chlorination product and aromatic amine compound molar ratio of 1-3:1 is derivatized in chloroform solution for 5-10 minutes at room temperature, and then chloroform is distilled off to obtain a graphene oxide chlorination product derivative. USE - Method for preparing high flux anti-penetrant film taking oxidized graphite alkene acyl chloride derivative product. ADVANTAGE - The method enables to prepare high flux anti-penetrant film taking oxidized graphite alkene acyl chloride derivative product, which increases the diversity of the interfacial polymerization reactionprocess, reduces the crosslinking density, in order to get higher throughput on the space structure. DETAILED DESCRIPTION - Preparing high flux anti-penetrant film taking oxidized graphite alkene acyl chloride derivative product involves preparing 0.1-0.3g/L graphene oxide and 0.1-lg/L thionyl chloride of the modifying agent inisoparaffin solvent, mixing them uniformly, distilling off the thionyl chloride at -0.1mega pascals to -0.03mega pascals ay 50-80 degrees C to obtain a graphene oxide chlorination product. The obtained graphene oxide chlorination product and aromatic amine compound molar ratio of 1-3:1 is derivatized in chloroform solution for 5-10 minutes at room temperature, and then chloroform is distilled off to obtain a graphene oxide chlorination product derivative, followed by taking a polyfunctional aromatic amine compound dissolved in water to obtain an aqueous phase solution of 0.5-10 wt.%, soaking the support layer in the aqueous phase solution, and removing the excess aqueous phase solution on the surface of the support layer. The product is immersed in a mixed oil phase solution of a polyfunctional acid chloride and a graphene oxide chlorination product derivative, where the mixed solution is a solution of 0.1-2 wt.% the polyfunctional acid chloride and 0.001-0.01 wt.% graphene oxide chlorinated product derivative in an organic solvent. The excess oil phase solution on the surface is removed, and the oil phase solution is evaporated to obtain a reverse osmosis membrane. The reverse osmosis membrane obtained is dried at 60-100 degrees C for 80-600 seconds to obtain the polyamide reverse osmosis membrane modified by the acid chloride oxide graphene derivative.
