Embodiment Construction

[0020] 1. Raw materials:

[0021] Pyrrole, ε-caprolactone, Nitromethane, Tetrabutylammonium boron tetrafluoride. Pyrrole was distilled under reduced pressure and stored in a 0°C refrigerator for later use.

[0022] 2. Electrolyte preparation:

[0023] Add pyrrole and ε-caprolactone into the nitromethane solution, add boron tetrafluoride tetrabutylammonium as supporting electrolyte, and mix the solution evenly. And make the pyrrole concentration 0.1~0.4moldm -3 , the concentration of caprolactone is 0.1~2.0moldm -3 , the concentration of tetrabutylammonium boron tetrafluoride is 0.05~0.1moldm -3 .

[0024] 3. Electrolytic cell preparation:

[0025] The electrolytic cell adopts a three-electrode system, the working electrode is conductive glass, and the counter electrode is platinum wire electrode. Ag / AgCl (saturated KCl) was the reference electrode. The conductive glass is rinsed with distilled water and acetone solution respectively before use. Platinum wire electrode...

Description

technical field [0001] The invention relates to a polymer with conductive properties and a synthesis method thereof, belonging to the technical field of electrochemistry. Background technique [0002] Conductive polymer refers to a polymer material whose main chain is a conjugated structure with highly delocalized electrons and is doped with electron donors or electron acceptors. The conductivity of such materials after doping is generally 10 -6 ~10 5 s / cm, the reason why the conductive polymer has attracted a lot of attention is because it has many excellent properties and very broad application prospects. This type of material itself is an organic polymer, which has the characteristics of light weight and designable structure of general polymers; their electrical conductivity reaches the range of semiconductors and metals, and can be adjusted artificially. It can be seen that they have the characteristics of polymer materials. , the advantages of semiconductor materials...
