The preparation method of described water-soluble high temperature-resistant polyaniline conducting material is as follows:
1, Sodium phosphate dibasic and the SODIUM PHOSPHATE, MONOBASIC mixed solution with pH=7 fully dissolves 0.05～3 part of horseradish peroxidase as damping fluid, makes horseradish peroxidase solution;
2, be that 54～216 parts of Ursol D are dissolved in the deionized water with weight, and fully stirring make its dissolving, adds 35～71 parts of monomer vinylformic acid then, stirs;
3, the above-mentioned horseradish peroxidase solution that makes is added the above-mentioned liquid that stirs, drip weight concentration then in batches and be 0.3%～0.03% superoxol, added 1 time in per 20～35 minutes, 0.2～1 part/time, add altogether 4～6 times, the inflated with nitrogen protection was reacted 20～30 hours;
4, products therefrom is directly joined in the acetone soln, precipitation, washing, 48 ℃～80 ℃ vacuum-drying 45～52 hours promptly makes product of the present invention.
The present invention has following advantage:
1, the preparation of this material is to be catalyzer with the biological enzyme, removes the dried up solvent that is, reaction is the solution polymerization of homogeneous, avoided initiators such as Sodium Persulfate commonly used, organic solvents such as dioxane have reduced environmental pollution, and significantly reduce the enzyme amount, reduced cost.
2, the polyaniline compound electro-conductive material of the present invention preparation is simultaneously soluble in water, and is dissolved in the stronger organic solvent of other polarity, and has certain electroactively, and specific conductivity is 10-5S/cm.
3, this material has good thermostability, and second-order transition temperature is up to 410.4 ℃, residue 66.2% when quality still remains between 81.5%, 600 ℃-900 ℃ weightless 3.2%, 1198 ℃ when being heated to 900 ℃.
