%X This paper focused on preparation of CuO-TiO2/conductive polymer fiber composites and its photocatalytic degradation of methylene blue. Firstly, conductive polymer fiber was prepared by electrospinning. Ti4+ ions were then introduced onto the conductive polymer fiber surface by coordinating with carboxyls of SMA. TiO2 particles were synthesized by hydrothermal synthesis, and CuO particles were grown on the surface of TiO2 particles. The structure of CuO-TiO2/conductive polymer fiber composites were characterized by Field-emission scanning electron microscopy (SEM), X-ray diffraction (XRD), Ultraviolet-visible (UV-Vis) and Thermo-gravimetric analysis (TGA). The degradation of methylene blue (MB) aqueous solution with the composites as the catalyst was performed under Xe lamp irradiation. The results showed that the composites had good photocatalytic efficiency. After 3.5 h photocatalytic reaction, the residual quantity of methylene blue was 4.7%.
