Example Embodiment

[0025] The typical steps for synthesizing conductive polymer/carbon nanotube composite mesoporous nanotubes are as follows:
[0026] 1. Mix carbon nanotubes (including single-walled, double-armed and multi-walled carbon nanotubes) and potassium permanganate aqueous solution (0.01M ~ 1M), react at 50 ~ 100 ° C for 1 ~ 20 hours, precipitate and disperse and pass through Separation by filtration to obtain a carbon nanotube composite nanostructure coated with manganese dioxide. The potassium permanganate aqueous solution is more than five times the mass of the carbon nanotubes, and the potassium permanganate aqueous solution in this embodiment is twenty-five times the mass of the carbon nanotubes, and the reaction is carried out at 70° C. for 6 hours.
[0027] 2. Preparation of conductive polymer/carbon nanotube composite mesoporous nanotubes, MnO 2 The raw materials of @CNTs are dispersed in a solvent (solvent including water and ionic liquid, etc.), and the conductive polymer monomer is dissolved in a solvent of protonic acid (sulfuric acid or dodecylbenzenesulfonic acid, respectively) (solvent includes water and In the ionic liquid such as 1-butyl-3-methylimidazole tetrafluoroborate, etc.), the pH value range in the embodiment is especially between 1~4, the reaction time is 10 minutes~72 hours; the reaction temperature is at room temperature~ Within the range of 100 °C, perfluorooctane sulfonic acid can be selected as an organic acid, and hydrochloric acid can be selected as an inorganic acid, and similar results can be obtained.
[0028] (3), MnO 2 The template itself participates in the reaction and can be spontaneously dissolved and removed after the reaction is completed.
[0029] (4) The synthesized conductive polymer accurately replicates MnO 2 The micro-nano structure of the template forms hollow conductive polymer/carbon nanotube composite mesoporous nanotubes.
