Description
Technical Field
The invention relates to the technical field of electrode materials of supercapacitors, in particular to a polyfluorinated functional polybenzazole electrode material applied to a supercapacitor and a preparation method thereof.
Background
With the rapid consumption of fossil fuels and the increasing deterioration of environmental pollution caused by the consumption of large amounts of fossil fuels, there is an increasing demand for the effective utilization of energy and the search for renewable and clean energy sources that can replace fossil fuels. Energy storage is an intermediate step in achieving versatile, clean and efficient use of energy and has attracted extensive attention and increased research interest worldwide. Compared with the traditional capacitor, the super capacitor is an electrochemical energy storage device with great development prospect, and has the characteristics of high energy density, good power density, fast charge and discharge, long cycle life and the like, so that the super capacitor has attracted extensive attention in academic and industrial fields in the past decades.
As an extremely important electrode material of a super capacitor, the preparation process of the conductive polymer is simpler, the cost is lower, and the comprehensive performance is more excellent, including higher conductivity and electrochemical activity, so that the conductive polymer becomes one of the most promising electrode materials of the super capacitor. Compared with typical conducting polymers polyaniline, polypyrrole and polythiophene, polybenzazole belonging to a condensed ring family bears the structural characteristics of polyparaphenylene and polypyrrole, so that the polybenzazole has the advantages of good thermal stability, electrochemical reversibility and the like, and is receiving more and more attention. However, the specific capacitance of pure polybenzazole prepared by direct electropolymerization only reaches 103F g-1, and the capacitance retention rate after 5000 circles is only 68%, which greatly limits the application of the polybenzazole in the field of supercapacitors. Based on this problem, structural modification is an important way to modify polymers.
Fluorine atoms have a high electronegativity and a minimum atomic radius (excluding H), and fluorine-containing groups are regarded as a special group for improving polymer properties. The existence of fluorine atoms can often form stronger hydrogen bonding action in molecules and among molecules, the introduction of a plurality of fluorine atoms can further strengthen the interaction force among molecules, and the introduction of a plurality of fluorine atoms can not cause excessive steric hindrance among molecules, so that the polymer has better thermal stability, oxidation stability and structural stability. The introduction of a plurality of fluorine atoms reduces the surface energy of the polymer, thereby greatly improving the morphological structure of the polymer, providing more active sites for pseudocapacitance reaction, and having positive influence on the improvement of the capacitance performance of the conductive polymer. However, after multi-fluorination of aniline, thiophene or pyrrole with a single-ring structure, the electrochemical activity of the corresponding polymer is obviously reduced, and indole has a special condensed-ring structure, so that the invention utilizes the multi-fluorination to regulate and control the capacitive performance of polybenzazole, and provides valuable reference for developing novel high-performance conductive polymer electrode materials.
