Composite molecularly imprinted nanofiber membranes with selectivity and adsorption behavior to bisphenol A derivatives
Molecularly imprinted nanoparticles are cross-linked polymer colloids containing tailor-made molecular recognition sites. In this study, molecularly imprinted nanoparticles were easily encapsulated within polymer nanofibers using an electrospinning technique to produce a new type of molecular recognition material. A modified precipitation polymerization (MPP) method was employed to prepare molecularly imprinted polymer microspheres for selective recognition and binding of bisphenol A (BPA). Polysulfone (PSf) was used as the supporting nanofibers matrix to encapsulate BPA imprinted nanoparticles. The composite nanofibers had an average diameter of 400-600 nm, depending on the content of molecularly imprinted nanoparticles. For the BPA imprinted polymers, an optimal loading of molecularly imprinted nanoparticles was 25～50 wt % based on PSf. The composite nanofibers prepared under these conditions had a well-defined morphology and displayed the best selective target recognition.
