摘　　要：A novel molecularly imprinted composite nanofiber was prepared by a simple electrospinning technique, in which polyvinylbutyral （PVB） was chosen as matrix, fl-cyclodextrin （β-CD） was used as a functional monomer and naringin （NG） as template molecules. After cross-linked by hexamethylene diisocyanate （HMDI）, the composite nanofiber exhibited a high specific binding capacity. The morphological structure of the nanofibers was studied by means of infrared spectrum （IR）, X-ray diffraction （XRD）, and scanning electron microscopy （SEM）. The β-CD molecules were mostly homogeneously distributed within the PVB nanofiber without forming phase separated crystalline aggregates. Compared with traditional imprinted β-CD polymer, the binding experiments demonstrated that the molecularly imprinted composite nanofiber shows the specific binding sites and the selective binding ability for NG. The molecularly imprinted nanofiber could be used at least six times without any loss in binding capacity.A novel molecularly imprinted composite nanofiber was prepared by a simple electrospinning technique, in which polyvinylbutyral （PVB） was chosen as matrix, fl-cyclodextrin （β-CD） was used as a functional monomer and naringin （NG） as template molecules.
