Abstract
The present invention relates to a novel carbon nano-particle and a novel method of preparing the same and a transparent, conductive polymer composite containing the same. The carbon nano-particle has the mean diameter of 1 through 50 nm and the shape of sphere, rod or others, which is a novel material not known in the relevant art. Because of a particle size less than ½ of the shortest wavelength of a visible ray, a transparent resin containing the carbon nano-particle can maintain the transparency. Furthermore, the carbon nano-particle has the excellent electric conductivity and the ferromagnetic property, and can be made by a novel, low cost method entirely different from those of fullerene and carbon nanotube.
