Polythiophene(Pth) is easy to be modified, and holds others unique properties, including that, the degree of polymerization can be controlled, and the nanofibers prepared under special conditions are stronger than aluminum. As a new type of polymer material, polythiophene is the main material for organic semiconductors, electrode materials and sensors. But the mechanical failure of polythiophene materials may lead to the malfunction or even failure of the entire device. However, related researches on the mechanical properties of Pth are mainly concentrated on bulks or films. None of these research has been done on the mechanical properties of single Pth nanofibers. In this thesis, the mechanical properties of Pth nanofibers were experimentally studied and analyzed. For example, the adhesion properties of Pth nanofibers were studied and analyzed. The adhesion between the same probe and Pth nanofibers in the diameter range of 85-180nm was systematically tested by atomic force microscopy. The test results demonstrated that the average adhesion between the Pth nanofibers with the length range of 8-23μm and the AFM probe was 107.02±7.06 nN. After comparing the adhesion test results between the same AFM probes and different nanofibers such as Pth nanofibers, PVDF nanofibers and silver nanowires, it was found that the adhesion between Pth nanofibers and the AFM probe was stronger than that of the others.
