An estrone imprinted polyimide nanofiber mat was prepared by an electrospinning method. A poly(amic acid) was synthesized by step-reaction polymerization of a diamine monomer-template complex, ODA, and PMDA in DMF. The diamine monomer-template complex was synthesized by the reaction of the diamine monomer having an isocyanate group and estrone having a phenol moiety, in which the template was attached to the monomer via a thermally reversible urethane bond. The poly(amic acid) was electrospun and thermally treated for imidization. After removing the template molecules, the specific recognition ability of the imprinted nanofiber to the estrone and its structural analogues was investigated by reverse phase HPLC analysis. The kinetic adsorption of estrone to the nanofiber was also studied. |
