Embodiment 1

[0022] First mix sodium bismuthate and zinc acetate evenly, wherein the molar ratio of sodium bismuthate to zinc acetate is 38:1, then place the mixed powder of sodium bismuthate and zinc acetate in the high temperature zone of the corundum tube reaction vessel, and place the polyaniline In the low-temperature zone of the corundum tube reaction vessel, the weight of polyaniline accounts for 30% of the weight of sodium bismuthate and zinc acetate, and the corundum tube is sealed, and the high-temperature zone is heated to a temperature of 1400°C, and the low-temperature zone is heated to 300°C. The air velocity is 200cm 3 / min, thus obtaining polyaniline-composite zinc bismuthate nanorods with a diameter of 20-100 nm and a length of 1-2 μm on the surface of the water-cooled end of the corundum tube, with random polyaniline particles attached to the surface.

Abstract

The invention discloses a preparation method of polyaniline compounded zinc bismuthate nano-rods, and belongs to the technical field of preparation of functional materials. According to the preparation method, sodium bismuthate, zinc acetate and polyaniline are used as raw materials, and argon is used as carrier gas. The preparation method comprises the following specific steps: uniformly mixing the sodium bismuthate with the zinc acetate at first; and then placing mixed powder of the sodium bismuthate and the zinc acetate in a high-temperature region of an alundum tube reaction container, placing the polyaniline in a low-temperature region of the alundum tube reaction container, sealing the reaction container, heating the high-temperature region to the temperature of 1,200-1,400 DEG C, heating the low-temperature region to the temperature of 200-300 DEG C, and insulating for 12-24 hours, wherein the flow speed of the argon is 100-200 cm<3> / min. A preparation process is simple and is easy to control, and the polyaniline compounded zinc bismuthate nano-rods have good application prospect in the fields of electronic devices, optical devices, electrochemical devices, lithium ion batteries and the like.
