Abstract

The invention relates to a preparation method of a solid aristate spherical conducting copolymer, which comprises the following steps: (1) dissolving a certain mass of ferrous chloride in deionized water in a three-neck flask at the stirring rate of 300 r/min to obtain a 2.0-5.0*10<-2> mol/L ferrous chloride solution, stirring uniformly by ultrasonic dissolution, and putting in a cold bath for later use; (2) adding 0.23 mL of pyrrole monomer into the uniformly stirred ferrous chloride solution, and continuing stirring for 30 minutes until the solution is uniformly mixed; (3) adding 0.34 mL of aniline monomer into the uniformly stirred ferrous chloride/pyrrole monomer mixed solution, and continuing stirring for 30 minutes until the solution is uniformly mixed; (4) slowly and dropwisely adding an isopropyl benzene hydroperoxide solution into the mixed solution while stirring, and increasing the stirring rate to react at 0 DEG C or so for 24 hours, thereby obtaining a brown reaction solution; and (5) carrying out solid-liquid separation on the obtained reaction solution, recovering the liquid for later use, washing the solid with water and alcohol three times, and drying at 60 DEG C in an air atmosphere for 24 hours, thereby obtaining the solid aristate spherical polypyrrole/polyaniline copolymer. The method prepares the solid aristate spherical polypyrrole/polyaniline copolymer by using isopropyl benzene hydroperoxide and ferrous chloride as the redox system for the first time; and the conductive polymer in such a structure has many potential applications in the fields of supercapacitor electrode materials, gas sensors and lithium battery materials.
