Embodiment 1

[0035] 0.4320g FeCl 3 ·6H 2 O and 0.2224 g FeSO 4 ·7H 2 O(Fe 3+ : Fe 2+=2:1) ​​was dissolved in 150 ml of deionized water, and nitrogen gas was passed through for 5 minutes. Add dilute ammonia water under the condition of rapid stirring at room temperature, the color of the solution changes, stop dripping ammonia water when the solution turns completely black. Stirring was continued for 1 hour after the dropwise addition was complete. The obtained solution was centrifuged (5000 rpm, 5 minutes), and the precipitate obtained was washed 3 times with deionized water, and the precipitate was dispersed in deionized water to form a 250ml solution. Add 12.5 g of sodium polystyrene sulfonate solution (20% concentration) to the above solution, and stir at high speed for 4 hours. Add 1g of EDOT monomer, 2.26g of ammonium persulfate, 0.025g of ferric sulfate under stirring, drop in hydrochloric acid to adjust the pH value to 2-3, and stir at high speed for 24 hours. The mixed solu...

Abstract

The invention discloses a process for preparing nanometer composite material of poly thiofuran metal-oxide. The process for preparation is as follows: charging nanometer composite material into solution, and then charging sodium polystyrene sulfonate solution to agitate at high speed or scatter though supersonic, under the obtained solution is agitated, charging thiofuran monomer, oxidant and accelerant respectively, which the mol ratio between the oxidant and the monomer is 0.1-5 and the mol ratio between the accelerant and the monomer is 0.001-0.01, dropping hydrochloric acid to regulate the pH level between 2 and 5 and agitating at high speed for 24-48 hours, drying the obtained miscible liquids at 60-120 DEG C for 3-12 hours, and milling the solid to obtain the nanometer composite material of poly thiofuran metal-oxide. The invention solves the problems effectively of easily agglomerate metal-oxide nanometer particle, bad stability of chemical stability, the composite material has the advantages of simple preparing process, low the cost of the preparing and better property of light, electricity and magnetism and the like.
