Polyaniline Having Highly Electrical Conductivity and Process of Preparing the Same

摘要

The invention to have a repeating structure represented by the general formula, ¹³ C CPMAS the characteristics of the spectrum is a peak is formed in the vicinity of 138 ppm and 143 ppm, the peak intensity (I in the 143 ppm peak intensity (I _138ppm) at 138 ppm _{It relates} to a polyaniline and a method for producing the same, characterized in that greater than _143ppm ).; General formula ;(Wherein x and y are mole fractions of the quinonediamine structure and the methylenediamine structural unit, respectively, and satisfy 0 x 1, 0 y 1, x + y = 1).;The polyaniline synthesized according to the present invention has an electrical conductivity of up to 100 times or more compared to the conventional polyaniline and improves solubility and processability, and thus may be applied to conductive films, fibers, polymer blends, electromagnetic shielding or transparent electrodes of thin films.
