Abstract

The invention discloses a method for preparing conducting polyaniline nanotubes with fructose as the template. The method includes the steps that fructose is weighed and added into a flask containing 30 mL of deionized water, stirring is carried out for 0.5 h at the room temperature, and the flask is transferred into an ice-water bath; then, 1 mL of aniline and 10 mL of a 1 mol / L hydrochloric acid solution are added into the flask, stirring is carried out for 1 h under the ice-water bath, and a mixed solution is obtained; then, an ammonium persulfate solution is dropwise added into the mixed solution, stirring is carried out for 12 h under the ice-water bath, then a reactant is subjected to washing and suction filtration with deionized water till filter liquor is neutral, an obtained filter cake is dried for 24 h in a 50 DEG C vacuum drying oven, ground and collected, and the conducting polyaniline nanotubes are obtained. According to the method, the preparation process is simple, environmentally friendly and reliable, the raw materials are wide in source and low in cost, and the method is suitable for industrial production; besides, the obtained conducting polyaniline nanotubes are regular in structure, low in resistance and high in specific capacitance.

Description

technical field [0001] The invention belongs to the technical field of preparation of conductive polymer materials. In particular, it relates to a method for preparing conductive polyaniline nanotubes using fructose as a template. In this method, fructose is used as a template, and conductive polyaniline with nanotube structure is prepared through self-assembly and in-situ polymerization of aniline. Background technique [0002] As a common conductive polymer, polyaniline is often used in supercapacitors, batteries, sensors and anti-corrosion fields due to its simple preparation, low cost, good environmental stability and unique physical and chemical properties. The great attention of scientific researchers all over the world. In particular, conductive polyaniline with nanostructures, due to its extremely small particle size, large specific surface area, and extremely fast electron transfer rate, endows nano-conductive polyaniline materials with many unique properties that...
