  Abstract

A facile method for the preparation of porous micro/nano fibers was demonstrated. The TiO2/PVDF/CA-composite micro/nano fibers were prepared by centrifugal spinning and then CA was removed by a selective dissolution: reaction with the solution of Acetic Acid. The obtained TiO2/PVDF/CA micro/nano fibers showed highly porous surfaces after the extraction of CA. The structure and properties of PVDF/CA micro/nano fibers were characterized by fourier transform infrared (FTIR), and thermogravimetry (TG), and scanning electron microscope (SEM). The results indicated that CA could be introduced into the PVDF solution and PVDF/CA-composite fibers could be fabricated via centrifugal spinning successfully. CA is dissolved and pores are formed on the fibers. The morphology image of the fibers was detected by scanning electron microscope (SEM) and showed that many pores aligned the nanofibers. The photocatalytic degradation properties of the treated composite fibers were studied. The results showed that the composite fibers prepared by centrifugal spinning had good degradation effects for different concentrations and dyes, and the composite fibers had good reusability.
