▎ 摘　　要

NOVELTY - Preparing thiophene selective graphene bionic mineralization film comprises (i) dissolving surfactant, polydimethylsiloxane oligomer, graphene oxide and methyl orthosilicate in n-heptane, stirring at room temperature to obtain first mixed solution, (ii) dissolving cystamine in tris-hydrochloric acid buffer solution to obtain inducer, (iii) dropping inducer in first mixed solution, stirring for 20-40 minutes, dropping catalyst to obtain second mixed solution, and (iv) taking polyvinylidene fluoride micro-filtration membrane as supporting layer, casting second mixed solution on polyvinylidene fluoride micro-filtration membrane at room temperature, drying in air and annealing. The catalyst is dibutyltin dilaurate. USE - The method is useful for preparing thiophene selective graphene bionic mineralization film. ADVANTAGE - The bionic mineralization film: has excellent compatibility, high permeation flux and high enrichment factor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for thiophene selective graphene bionic mineralization film prepared by the above mentioned method.
