| Recently, there has been growing research interest in the design and fabrication of novel multifunctional materials due to their extensive applications in contrast to their counterpart single functional micro/nanomaterials. Therefore, research on multifunctional materials has been one of the popular subjects of study in the materials science. Novel one-dimensional nanostructured materials with simultaneous luminescence-electricity-magnetism trifunctionality have important impacts on the development of future nanoscience and nanotechnology. Electrospinning has been proved to be one of the best methods to fabricate one-dimensional nanomaterials owing to its simple operation, strong controllability and reproducibility. Hence, electrospinning has become an ideal technique to farbricate these kinds of nanomaterials.In this thesis, {[Dy（BA）3phen+Eu（BA）3phen]/PANI/PMMA}@[Fe3O4/PMMA] coaxial nanoribbons（namely shell@core）, {[Eu（BA）3phen+Tb（BA）3phen]/PMMA} @[Fe3O4/PANI/PMMA] belt-shaped coaxial microcables, {[Eu（TTA）3（TPPO）2+ Tb（TTA）3（TPPO）2]/PMMA}@[Fe3O4/PANI/PMMA] coaxial nanoribbons and their arrays with tunable multicolor luminescence, electrical conductivity and magnetism were prepared via electrospinning technology.The samples were systematically characterized by modern measurement techniques and some meaningful results were obtained. The results revealed that emitting color of the coaxial micro/nanomaterials can be tuned by adjusting the contents of RE complexes, PANI and Fe3O4 in a wide color range under the corresponding excitation of single-wavelength ultraviolet light. The coaxial micro/nanomaterials simultaneously possess excellent luminescent performance, electrical conduction and magnetism. Furthermore, the electrical and magnetic performances of the coaxial micro/nanomaterials also can be tunable by adding different quantities of PANI and Fe3O4 nanoparticles, respectively. |
