β-cyclodextrin (β-CD) can form a unique host-guest inclusion complex with organic molecules due to the suitable cavity size and specific molecular recognition. It can be used as an adsorption material to purify the polluted water. However, the well water solubility of β-CD restricts its in-depth application in water systems. Therefore, it is considered that β-CD can be introduced into an electrospun fibers membrane with relatively high specific surface area to synergize the advantage of the cyclodextrin and the electrospun membrane to acquire an easily removable composite adsorbent. Herein, the axial polyacrylonitrile fibers membrane and the coaxial fibers membrane of polyvinylidene fluoride@ polystyrene, containing β-CD were prepared by using the method of electrospinning respectively. Adsorption capacity of organic molecules of the functionalized fibers membrane were investigated. Further analysis demonstrated that remarkable adsorption capacity towards organic molecules was ascribed to the formation of inclusion complexes with β-CD to some extent.
