摘要

The present invention relates to a method for producing a porous polyaniline / carbon nanotube nanocomposite using carbon nanotubes, which comprises preparing carbon nanotubes having a size of 1 to 15 nm and having a carboxyl group on the surface thereof, To provide a unique method of inhibiting the agglomeration of polyaniline and forming pores. According to the present invention, it is possible to easily produce a polyaniline / carbon nanotube nanocomposite having a surface area increased by adding pores to a polyaniline polymerization solution by simply preparing the carbon nanotubes. The polyaniline / carbon nanoparticle nanocomposites with increased surface area due to the effect of carbon nano-dots have been shown to improve the interaction between the dopant camphorsulfonic acid and the methacresol solvent, and thus the polyaniline / carbon nanoparticle nanocomposite It is possible to manufacture a thin film. When the prepared polyaniline / carbon nano-dot nanocomposite thin film was used as a counter electrode of a dye-sensitized solar cell, the electrocatalytic activity was improved due to the improved electrical conductivity, and the electric power of the dye- An increase in power conversion efficiency can be expected.
