Preparation of aligned conjugated polymer fibers by electrospinning

In this work, we studied the property of pure conjugated polymers P3HT and P3HT blend with PCBM films and fibers that prepared by spin coating and electrospinning. The purpose of this work is to study the technology and application of electrospinning using low molecular weight conductive polymer and didn't add salts to solution. Part I: Preparation the conductive polymer solution that dissolved in the different solubility solvents, then prepared films and fibers by spin coating and electrospinning process. We found that using binary mixed solvent could prepared a large number of pure conjugated polymer fibers. Part II: we focused on the control the electrospinning fiber by changing the way of collect and collect, then the fibers can be controlled and that it would be more regular and orderly arrangement. Then, we explored the quality of the surface morphology of pure conjugated polymer electrospun single fiber by AFM scanning. We explored the fibers surface morphology and diameter by using FESEM. We used XRD to compare crystallization characteristics of conductive polymer films and fibers. Finally we explored and examined optical properties by use UV-Vis spectrometer.
