Description
Technical field
The present invention relates to a kind of three-dimensional grapheme/polyaniline array electrode material for super capacitor preparation methods.
Background technique
Supercapacitor is as a kind of novel electric energy storage device, energy density and power density with superelevation, compared with
The advantages that high cyclical stability.Double layer capacitor can be mainly classified as by its energy storage mechnism difference and pseudocapacitors two are big
Class.Double layer capacitor is to realize the storage of charge in electrode material surface adsorption desorption by electrolyte ion and release
It puts.Therefore want that obtaining higher energy density needs electrode material to have biggish specific surface area.Graphene is a kind of only single
The two-dimensional material of atomic layer level thickness, electric conductivity and excellent mechanical property with superelevation, while its specific surface area may be up to
2630m2×g-1, therefore graphene is considered as a kind of ideal electrode material for super capacitor.
Nearest three-dimensional grapheme causes the concern of many researchers, three-dimensional porous structure because of its excellent performance
Bigger specific surface area can be provided, while the generation of graphene agglomeration can be prevented, the effective electrification for improving material
Learn performance.But individually using three-dimensional grapheme as electrode material for super capacitor, due to the energy storage mechanism of its electric double layer, storage
Capacity is lower, is not able to satisfy actual demand.Therefore by three-dimensional grapheme and fake capacitance material, (transition metal oxide and conduction are poly-
Close object) it combines, while using the performance advantage of two kinds of materials, becoming the primary hand for improving three-dimensional grapheme chemical property at present
Section.Polyaniline is a kind of very widely used electrode material for super capacitor, its conductive energy is high, theoretical specific capacity
High, the advantages that synthetic method is simple and cheap.It is prepared to the super electricity of graphene/polyaniline in conjunction with three-dimensional grapheme
Container electrode material has become the hot spot of current electrode material for super capacitor research.Wherein, graphene oxide because its surface it is big
The oxygen-containing group of amount can provide active site for the polymerization of aniline, be easily formed stable three-dimensional structure and widely paid close attention to.
(Yu Pingping,Zhao Xin,Huang Zilong,et al.Free-standing three-dimensional
graphene and polyaniline nanowire arrays hybrid foams for highperformance
flexible and lightweight supercapacitors.Journal of materials chemistry A,
2014,2:14413-14420.) Yu et al. is immersed in nickel foam as template in the aqueous solution of graphene oxide, makes to aoxidize stone
Black alkene is wrapped in foam nickel surface, is then defoamed nickel template using hydrochloric acid solution, and obtain three-dimensional stone by electronation
Black alkene material.It adds it in aniline monomer solution, impregnates 180min, polymerization accelerant polymerization is added and obtains three-dimensional stone for 24 hours
Black alkene/carbon/polyaniline super capacitor electrode material.Electrochemical property test is carried out to material, specific capacitance can reach 790F/g,
And its capacity retention rate still can reach 80% after 5000 circulations.This aspect is because graphene is the quick biography of electronics
It is defeated to provide channel, it is on the other hand because polyaniline is well-regulated to arrange the specific surface area for increasing material, thus effectively
Improve the chemical property of material.(Meng Yuena,Wang Kai,Zhang Yajie,et al.Hierarchical
porous graphene/polyaniline composite film with superior rate performance for
Flexible supercapacitors, Advanced materials, 2013,25 (48): 6985-6990.) Meng etc. is by oxygen
Graphite alkene dispersion liquid, calcium chloride and ammonia spirit mixing, and it is passed through carbon dioxide gas thereto, form graphene oxide packet
The three-dimensional porous structure of calcium carbonate template is wrapped up in, then uses hydrazine steam reduction graphene oxide, and remove carbonic acid with hydrochloric acid solution
Calcium template obtains three-dimensional grapheme, adds it in the perchloric acid solution containing aniline monomer and is slowly stirred, then thereto
Polymerization accelerant is added, is reacted under condition of ice bath for 24 hours, after product washing drying, obtains three-dimensional grapheme/carbon/polyaniline super electricity
Container electrode material.Due to its stable structure and biggish specific surface area, so that the material shows excellent electrochemistry
Performance.
In conclusion preparing three-dimensional grapheme/carbon/polyaniline super capacitor electrode material at present mostly with graphene oxide
For raw material, polyaniline is then prepared in conjunction with the graphene oxide after reduction by electrode of super capacitor by chemical polymerization
Material.Although graphene oxide provides binding site for aniline polymerization and to gather because there are a large amount of oxygen-containing functional groups on its surface
Aniline is in connection even closer, and graphene oxide is more serious to graphene-structured destruction during the preparation process, although through
Crossing reduction, still its electric conductivity is not restored completely, is unfavorable for the raising of electrode material chemical property.Therefore with knot
Structure is complete, morphology controllable, and the three-dimensional grapheme for the chemical vapour deposition technique preparation haveing excellent performance is raw material, prepares three-dimensional graphite
Alkene/carbon/polyaniline super capacitor electrode material is the effective means for improving its chemical property.
