SYNTHESIS AND OPTIMIZATION OF SULFONATED POLYANILINE AS ORGANIC CONDUCTIVE MATERIAL

Currently, the need for conductor and semiconductor materials is increasing due to the rapid technology developments, especially in the field of electronics. Materials that commonly used are relatively expensive inorganic compounds. Besides, there are several other disadvantages such as inflexible,...
