Preparation And Properties Of One-dimensional Nanomaterials Based On [60]Fullerene

Low-dimensional nanostructured materials, especially one-dimensional nanostructured materials possess a series of excellent properties, including optics, electronic, magnetic, mechanical, chemical properties, which differ from the traditional bulk materials due to the quantum size effect, minor dimension effect, surface effect and interface effect, thereby making them attractive for many new applications in many industry as well as high-tech fields. Preparation of the nanomaterials plays a key role in nanoscience research. Various methods have been used for the preparation of nanostructured materials. However, intriguing questions such as synthesis of nanomaterials with controllable size and shape remain unanswered even now. Among the different preparation procedures, Porous alumina template method is one of the most widespread methods to synthesize low-dimensional nanostructured materials due to the structural, shape, size of the nanostructured materials are controlled by the template used. This paper are focusing on the preparation of one-dimensional nanostructured materials based on fullerenes, studying the photoelectric of the composite nanowires of C₆₀ and polymers, in order to exploring the relationship between composition, structure and property, and to pay a way to use nanomaterials based on fullerenes. Firstly, we tried to synthesize [60]fullerene nanotubes by using porous alumina membrane as template, the template was repeatedly dipped into a benzene solution of C₆₀C₁₆, and the solvent was allowed to dry between dipping. After a number of dip-and-dry cycles, the templates were heated to 500℃under an argon atmosphere, then the C₆₀C₁₆ were decomposed and the products were crystal [60]fullerene nanotubes. The products were characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), high-resolution transmission electron microscope (HRTEM), selected-area electron diffraction (SAED), IR and UV-vis spectroscopy, Raman scattering (Raman). This provides a new method to synthesize one-dimensional materials based on fullerenes. Secondly, PVK nanowires and [60]fullerene-PVK composite nanowires were prepared by using alumina as template, and were characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), IR and UV-visible spectroscopy. This method can be easily used to prepare the one-dimensional nanostructured materials with controllable shape and size. The fluorescent and photoelectric properties of PVK nanowires and [60]fullerene-PVK composite nanowires have been investigated. The single nanowire of [60]fullerene-PVK composite have excellent photoconductivity, which may have potential applications in nanodevices.
