The Preparation Of Conductive Polymer Composite Materials, Characterization And Application Research

In recent years, conductive macromolecule has become a hot topic due to its wideapplication, polypyrrole and polyaniline, as the typical conductive polymer, restrict thedevelopment and application on account of their defects. The paper is mainly aboutmodifying the features of pyrrole and aniline by the methods of doping inorganic, by meansof electrochemical synthesis method and chemical method.Cyclic voltammetry was used to synthesize polypyrrole film on ITO cond-uctive glass,changing acid type and whether adding surface active agent to determine the synthesisconditions. on this basis, combined with TiO₂, through infrared spectroscopy （FT-IR）,scanning electron microscopy （SEM） and measurement of electrical conductivity tocharacterize the nature, the results show that coextruded film Py-TiO₂synthesized bylithium perchlorate and hydrochloric acid electrolyte under the condition of anion surfactantagent can be observed to have surface of smoothness, uniformity and densification throughSEM, and cyclic voltage current curve of coextruded films is similar to PPy.Perovskite-type oxides La_0.7Ca_0.3Cu_0.75Co_0.25O₃synthesized by application ofglycine-nitrate, with oxidant of FeCl3, polypyrrole synthesized through chemical oxidationmethod, and doped with bovine serum albumin （BSA） as well as composite materialPPy/La_0.7Ca_0.3Cu_0.75Co_0.25O₃/BSA of La_0.7Ca_0.3Cu_0.75Co_0.25O₃,feature characterized by FT-IR,SEM, XRD, and the paper also researches on electrochemical and photo catalytic propertiesof composite having doped inorganic. The results show three layers of composite materialcan improve the agglomeration of particles in a certain extent analyzed by SEM and thatcomposite materials show good electrochemical performance, in1mol/LKOH solutionsamples in the test of cyclic voltage current curve. Also polymer degradation rate of threelayers of composite to acid orange is obviously improved under the irradiation of mercurylamp, reaching85.5%.By changing the molar mass ratio of pyrrole, aniline, a series of pyrrole and anilinecopolymer are synthesized with the method of chemical oxidation method, featurecharacterized through FT-IR, SEM, and XRD to study the electrochemical performance. Theresults show through the infrared analysis, it succeeds in synthesizing pyrrole and anilinecopolymer and adjusts the property of pyrrole by adding different amount of aniline, andthat the electrochemical property of the cyclic voltage current curves is best when the molar ratio of pyrrole to aniline is1∶3.Not much research on copolymer and perovskite type oxide, on the bases ofexperimental results in the paper, a series of copolymerization of pyrrole andaniline/La_0.15Ca_0.85Cu_0.25Co_0.75complexes are made in the same way, that is, copolymerunder molar ratio of the pyrrole to aniline,1∶3, combined with perovskite-type oxidecomposites La_0.15Ca_0.85Cu_0.25Co_0.75, by changing the temperature and proportion of oxideLa_0.15Ca_0.85Cu_0.25Co_0.75.Feature characterized through the FT-IR, SEM, XRD, andresearched electrochemical and photo catalytic properties of copolymer complexes havingdoped inorganic, results show the copolymer complexes arrange in neat rows,agglomeration is obviously improved, and that the cyclic voltage current curve shows thegood performance of the capacitor, the degradation of photo catalysis to acid orange isapparent.
