Embodiment 1

[0023] Take by weighing 14g of aniline and dissolve in 140g of water, 42.5g of dodecylbenzenesulfonic acid is dissolved in the mixed acid solution of 100ml [HCL]=2mol / L and join in the reactor together, stir on electric mixer (rotating speed interval is 1000~ 1500 rev / min); after emulsifying for half an hour, add 1.12g of 300-1200 mesh inorganic oxide conductive powder ATO (antimony oxide doped tin oxide); after stirring for half an hour, the mixed solution is milky white. Weigh 27.4g Ammonium sulfate was dissolved in 274g of water, and then added dropwise into the reactor. The reaction temperature was controlled by an ice-water bath at 0-10°C, and the reaction occurred immediately. Blue, blue, blue-green, green, the final solution is dark green latex, filtered, separated, washed with distilled water until no sulfate radicals can be detected in the filtrate; vacuum-dried at 75°C to constant weight to obtain conductive powder ATO / polyaniline conductive polymer composite materia...

[0031] Weigh 14g of aniline and dissolve in 140g of water, dissolve 35.4g of camphorsulfonic acid in 100ml of water and add them to the reactor together, and stir on an electric mixer (the speed range is 1000~1500 rpm); after half an hour of emulsification, add inorganic Oxide conductive powder ATO (antimony-doped tin oxide) 1.4g; after stirring for another half an hour, the mixed solution was milky white. Weighed 32.9g of ammonium persulfate and dissolved it in 274g of water, then added it dropwise to the reactor, and controlled the reaction in an ice-water bath The temperature is 0-10°C, the reaction occurs immediately, after 1 hour of dropwise addition, react under stirring for 24 hours, the reaction solution changes from milky white to yellow-green, light blue, blue, blue-green, green, and the final solution is dark green latex , filtered, separated, and washed with distilled water until no sulfate group was detected in the filtrate; vacuum-dried at 75°C to constant weight ...

Embodiment 3

[0037] Weigh 14g of aniline and dissolve in 140g of water, dissolve 35.4g of camphorsulfonic acid or 42.5g of dodecylbenzenesulfonic acid in 100ml of [HCL]=2mol / L mixed acid solution and add them to the reactor together, and stir on an electric mixer (The rotation speed range is 1000-1500 rpm); after emulsifying for half an hour, add 1.4 g of inorganic oxide conductive powder ITO (indium-doped tin oxide); after stirring for another half an hour, the mixed solution becomes milky white. Weigh 27.4g of ammonium persulfate and dissolve it in 274g of water, and then add it dropwise into the reactor. The reaction temperature is controlled by an ice-water bath at 0-10°C, and the reaction occurs immediately. After 1 hour of dropping, react under stirring for 24 hours. It is yellow-green, light blue, blue, blue-green, green, and the final solution is dark green latex, filtered, separated, washed with distilled water until no sulfate group is detected in the filtrate; vacuum-dried at 75°...

Description

technical field [0001] The invention relates to a conductive polymer composite material, in particular to an inorganic oxide conductive powder / polyaniline conductive polymer composite material synthesized by chemical oxidation in situ polymerization and a method thereof. technical background [0002] The last Nobel Prize in Chemistry in the 20th century was awarded in October 2000 to three chemists who had made outstanding achievements in the research of conductive polymers: Haig from the United States, Mark Diarmid from the United States and Hideo Shirakawa from Japan. Tree. [0003] Conductive polymers can be divided into two categories according to their conductive mechanism: one is composite conductive polymer materials, that is, various conductive fillers are added to conventional polymer materials, such as metal powder, conductive carbon black particles or fibers, etc.; The other type is the intrinsic conductive polymer material, which is f...
