摘要：
Carbon microspheres (CMSs) were oxidized by a mixture of concentrated sulfuric acid and nitric acid (ratio of 3:1 by volume) to improve their surface activity. Then, poly(3-hexylthiophene): CMSs (P3HT:CMSs) composite film was prepared by spin-coating method with oxidized CMSs and P3HT mixture chloroform solution. Energy levels of oxidized CMSs were investigated by cyclic voltammetry, the morphology of the composite films was characterized by atomic force microscopy, optical performance was analyzed by ultraviolet-visible spectrophotometry and fluorescent spectrometry, and microstructures of the products were characterized by Fourier transformation infrared spectrometry and x-ray diffraction. The results indicate that suspension concentration of 30 mg/mL and spinning rate of 2500 rpm were appropriate for fabricating P3HT:CMSs composite films. Optical properties of the P3HT:CMSs blends were changed by annealing. This lays an experimental foundation for fabricating active layer of polymer solar cells with high photoelectric conversion and low cost.
