Features traditional proton acid doped polyaniline conductive polyaniline containing transition metal ions , this article uses the oxidation of transition metal complexes have been successfully synthesized conductive polyaniline containing transition metal ions , using infrared , ultraviolet and the elemental analysis of the products were characterized by their conductive properties and thermal stability properties . The main contents are as follows : 1 . The eigenstates synthesized polyaniline and polyaniline hydrochloride, to study its FT-IR spectrum , UV / VIS electronic absorption spectral properties, to observe the surface morphology and the X - ray diffraction patterns , and to examine their thermal stability in air , electrochemical properties , and solubility properties in common organic solvent , provided the basic data for the subsequent research . 2. By UV / Vis spectroscopy detailed research in organic solvents of different transition metal ions Cu 2 the the Fe 3 < / sup> Co 2 , Ni , the interaction between the 2 polyaniline molecular chain to find the law of their interactions , to confirm stronger coordination between the transition metal ions with polyaniline molecular chain / doping interaction . 3. Use of the oxidation of aniline with the transition metal complexes in solution method Synthesis of a transition metal-containing ion conductive polyaniline , and Cu 2 , for example detailed examination of the synthesis conditions ( including the reaction medium , the ratio of raw materials , reaction temperature and time ) on the the synthetic product yield and conductivity , to obtain the optimal synthesis conditions , and to study the infrared spectrum corresponding variation in their process , at the same time observing the morphology, X -ray diffraction pattern of synthetic products and compare eigenstates and polyaniline hydrochloride . Elemental analysis showed that the transition metal ions have been successfully incorporated in the polyaniline molecular chain . 4. Study synthesized product in nitrogen and air thermal decomposition process of weightlessness , compared with the eigenstates and polyaniline hydrochloride , to obtain detailed information of the thermal decomposition process of conducting polyaniline samples containing transition metal ions , the actual material The application provides a theoretical basis . 5. According to the experimental results , the transition metal ion doped polyaniline and to produce electronic conductivity preliminary mechanism .
