Multifunctional Al-doped core-shell structure SiC nanowire and preparation method and application thereof
The invention discloses a multifunctional Al-doped core-shell structure SiC nanowire and a preparation method and application thereof.SiO powder and Al powder are used as precursors and are ground and mixed, and a large number of Al-doped core-shell structure SiC nanowires can be synthesized on the surfaces of various matrixes at the low temperature. By means of the method, a large number of Al-doped core-shell structure SiC nanowires with the uniform size can be efficiently prepared at the low temperature at low cost. The prepared nanowire has good photoluminescence performance and can promote the self-healing performance of the coating at high temperature. The synthesized nanowire has the following characteristics that the diameter is distributed between 100 nm and 130 nm, the center of the nanowire is a crystalline Al-doped SiC core, the diameter is about 50-80 nm, the outer layer is an amorphous Al-doped SiO2 layer, and the thickness is about 30-50 nm. The composition elements of the nanowire are Si, O, C and Al, and the length of the nanowire can reach the millimeter level.
