Embodiment 1

[0015] Process and steps in the present embodiment are as follows:

[0016] (1) First, modify the nano-titanium dioxide. Take 0.05mol of nano-titanium dioxide and put it in 1000ml of concentrated mixed acid. The concentrated mixed acid is a mixed acid of concentrated nitric acid and sulfuric acid. The volume ratio of the two is: HNO 3 :H 2 SO 4 =1:1.5, heating and refluxing at 80°C for 8 hours, then filtering and washing with distilled water until neutral, drying, and finally high-speed ball milling for 4 hours to obtain modified nano-titanium dioxide. Since the nano-titanium dioxide itself has a phenomenon of coagulation, which is not conducive to industrial application, after treatment, it can be dispersed relatively uniformly and the degree of dispersion can be improved.

[0017] (2) Get 0.025mol of above-mentioned modified nano titanium dioxide and join in 100mL hydrochloric acid solution, the concentration of hydrochloric acid is 0.5mol / L, add 0.0005mol surfactant sodiu...

Embodiment 2

[0021] Process and steps in the present embodiment are as follows:

[0022] (1) First, modify nano-cerium oxide, put 0.05mol of nano-cerium oxide in 1000ml of concentrated mixed acid, the concentrated mixed acid is a mixed acid of concentrated nitric acid and sulfuric acid, the volume ratio of the two is: HNO 3 :H 2 SO 4 = 1:2, heat and reflux at 90°C for 10 hours, then filter and wash with distilled water until neutral, dry, and finally undergo high-speed ball milling for 6 hours to obtain modified nano-ceria. Since the nano-cerium dioxide itself has the phenomenon of coagulation, which is not conducive to industrial application, after treatment, it is dispersed relatively uniformly and the degree of dispersion is improved.

[0023](2) Get 0.02mol of the above-mentioned modified nano-cerium dioxide and join in 100mL sulfuric acid solution, the concentration of sulfuric acid is 1mol / L, then add 0.001mol surfactant polyethylene glycol, carry out ultrasonic dispersion for 3 ho...

Embodiment 3

[0027] Process and steps in the present embodiment are as follows:

[0028] (1) First, modify the nano-manganese dioxide, take 0.05mol of nano-manganese dioxide and put it in 1000ml of concentrated mixed acid. The concentrated mixed acid is a mixed acid of concentrated nitric acid and sulfuric acid. The volume ratio of the two is: HNO 3 :H 2 SO 4 = 1:3, heated and refluxed at 100°C for 14 hours, then filtered and washed with distilled water until neutral, dried, and finally subjected to high-speed ball milling for 8 hours to obtain modified nano manganese dioxide. Since the nano-manganese dioxide itself has a phenomenon of aggregation, which is not conducive to industrial application, after treatment, it can be dispersed relatively uniformly, and the degree of dispersion is improved.

[0029] (2) Get 0.01mol above-mentioned modified nano manganese dioxide and join in 65mL phosphoric acid solution, the concentration of phosphoric acid is 2.5mol / L, then add 0.0015mol surfactan...

Abstract

The invention discloses a conductive polyaniline composite electrode material and a preparation method thereof. The preparation method comprises the steps: adopting nano titanium dioxide, ceria, manganese dioxide, lead dioxide, zirconium dioxide, boron carbide and tungsten carbide as templates; directly polymerizing an aniline monomer on nano granules by an in situ polymerization method; adding a surface active agent by using acid as a doping agent at the ice water bath condition of 10 DEG C to 15 DEG C under the action of an oxidizer; adding the nano granules and the aniline monomer at the mol ratio of 1 to (4 to 10) into a system for reacting; and finally obtaining a powdery conductive polyaniline composite electrode material. The compounded conductive polyaniline composite electrode material has the characteristics of good product performance, high quality, simple operation, convenient operation, high reception ratio, low pollution, higher conductivity, high intensity, good thermal stability, good chemical stability, good electric catalytic activity and the like and can be used for nonferrous metal electrode cathode materials, photoconductive nano devices, super electric containers, field transmitting devices, sensor antistatic materials, electromagnetic shielding materials and the like.

Description

technical field [0001] The invention relates to a preparation method of a conductive polyaniline composite electrode material, which belongs to the technical field of preparation technology of new composite materials in chemistry and chemical industry. Background technique [0002] Among conductive polymers, polyaniline is known as the most likely conductive polymer for practical application because of its excellent electrical conductivity, good environmental stability, simple synthesis process, and low raw material cost. However, due to the small molecular weight and defects in the molecular chain of polyaniline synthesized by traditional methods, its electrical conductivity and mechanical properties are greatly reduced, which limits its practical application. [0003] Composite material technology, especially organic-inorganic composite material technology has opened up a new field for the research of exploring new materials. The combination of organic and inorganic mater...
