Abstract

The invention discloses a conductive polymer hollow sphere PACP@ titanium carbide composite material and a preparation method thereof. According to the preparation method, a PACP (a copolymer of polyaniline PANI and polypyrrole PPy) and ultrathin titanium carbide are compounded through a chemical oxidation method under a low-temperature condition to obtain a Ti3C2@ PACP hollow sphere nano composite material as an electrode material of a supercapacitor, an in-situ polymerization method is simple to operate, efficient and environment-friendly, and the hollow spherical PACP and the layered ultrathin Ti3C2 are compounded, so that the hollow spherical PACP and the layered ultrathin Ti3C2 can be in more sufficient contact, the specific surface area is larger, the particle transmission, diffusionand the like are better facilitated, and the energy storage performance of the conductive polymer hollow sphere PACP@ titanium carbide composite material used for the supercapacitor electrode is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of supercapacitor electrode material preparation, and in particular relates to a conductive polymer hollow sphere PACP@titanium carbide composite material and a preparation method thereof. 【Background technique】 [0002] The loss of global fossil energy and the aggravation of environmental problems have stimulated people's interest in developing green new energy. As a new type of energy storage device, supercapacitors have attracted widespread attention due to their outstanding advantages. Compared with traditional batteries, supercapacitors have many advantages such as short charging time, outstanding cycle stability, high safety, simple assembly, high power performance, and good reversibility, and have attracted extensive attention from scientific researchers. Undoubtedly, in the near future, supercapacitors will be found in all aspects of people's lives, ranging from clothing, housing and transportation...
