Polythiophene and its derivatives due to their unique electrochemical properties, good environmental stability, ease of preparation, such as physical and chemical properties of concern in the field of materials science and electrical conductors, nonlinear optics, microwave absorbing material The aspect is carried out extensive studies. This thesis by a chemical oxidation method, or an electrochemical SYSTEM three kinds of poly thiophene and its derivatives were prepared and used in situ chemical oxidative polymerization in the carbon nanotubes (CNT) surface-coated polymer prepared three kinds of novel complexes. Using a variety of testing methods and product characterization and determination of specific capacitance and conductivity. The main results are as follows: 1. Synthesized by the Stille reaction, 3 ', 4'-ethylenedioxy -2,2': 5 ', 2 \base) [3,4-b] and [1.4] diazinon (PZT3) two conjugated compounds by H NMR, UV - visible spectroscopy method of the target product was confirmed. 2. 0 ~ 5 ℃ Next, FeCl3 as the oxidant, in a chloroform solution of each of the 3 ', 4'-B stays dioxo -2,2': 5 ', 2 \- two (2 - thienyl) thiophene [3,4-b] and [1.4] diazine (PZT3) as a monomer, synthesized three polymers: poly (3 ', 4'-B stays dioxo-2 , 2 ': 5', 2 \triazine) (of Poly (PZT3)), where their energy gap respectively 2.05,2.40,1.61 eV; the the conductivity magnitude were 10-3,10-6,10-4; than capacitive average respectively 130,121,83 F / g. 3. tetraethyl ammonium tetrafluoroborate / acetonitrile system, 3 ', 4'-B stays dioxo -2,2': 5 ', 2 \electrochemical polymerization in the different potentials of a series of poly (3 ', 4'-ethylenedioxy -2,2': 5 ', 2 \TET Best polymerization potential of 1.05 V by UV - visible spectra of poly (3 ', 4'-ethylenedioxy -2,2': 5 ', 2 \sulfonic acid and different solvent doping behavior. The study results show that: the four solvents sulfonic acid doped the the PTET impact size: AN gt; CHCl3 gt; of THF gt; DMF; the three Acid Doped PTET ease of: NSA gt; p-TSA gt; MSA. 5 by in situ chemical oxidation polymerization method in the nanotube (CNT), the surface coating of three polymers were prepared in the carbon nanotube - poly (3 ', 4'-ethylenedioxy -2,2': 5 ', 2 \b] and [1.4] diazine) (the CNT / of Poly (PZT3)) three kinds of core-shell structure of the nano-composite. tests showed that the composite has excellent electrochemical properties.
