Example Embodiment
[0032] Example 1
[0033] A preparation method of polytriphenylamine-carbon nanofiber composite material, the specific steps are:
[0034] Step 1: Use electrospinning, imidization and high temperature carbonization to prepare flexible carbon nanofibers:
[0035] (1) Electrospinning: Add 0.1 mol p-phenylenediamine and 0.1 mol pyromellitic dianhydride to 30mL N, M dimethylformamide solvent at a molar ratio of 1:1, and dissolve at 0°C in a nitrogen environment The polycondensation reaction was conducted for 12 hours to obtain a polyamic acid solution. The obtained polyamic acid solution is subjected to electrostatic spinning, and the adjustment process parameters are: electrostatic field voltage 20kV, spinning speed 0.1mmmin -4 , The receiving distance is 20em, and the polyamic acid nanofiber membrane is prepared.
[0036] (2) Imidization: the polyamic acid nanofiber membrane is imidized in a nitrogen environment, the imidization temperature is 300℃, and the heating rate is 2℃min -1 , T...
