Abstract

The invention discloses a conjugated porous polymer capacitance material and a preparation method and an application; the chemical structural general formula of the conjugated porous polymer contains a tricarbazole structural unit. The preparation method includes steps of performing nitration of tricarbazole and acquiring trinitro-tricarbazole; preparing tri-amino- tricarbazole by trinitro-tricarbazole; at last, linking tricarbazole with aldehyde group or anhydride to form the conjugated porous polymer; acquiring the capacitance material. The conjugated porous polymer capacitance material is wide in application of energy storage domain, and can realize the circular charge and discharge for many times; the specific capacitance attenuation rate is low, the circular stability is good, the material structure is new, the preparation method is simple, and the cost is low; therefore, the conjugated porous polymer capacitance material is the capacitance material greatly possessed of application potential.

Description

technical field [0001] The invention belongs to the technical field of photoelectric materials and applications, and in particular relates to a conjugated porous polymer capacitor material and its preparation method and application. Background technique [0002] With the rapid development of human society in the past hundred years, the energy consumption on the earth is increasing. With the increasing demand for energy and power, we urgently need to find new electrode materials suitable for advanced energy storage devices. Among them, a supercapacitor is a storage device between a traditional electrostatic capacitor and a storage battery. Supercapacitors not only have a long service life and good stability, but also have high specific capacity and power density, so they will play an increasingly important role in modern energy storage. The electrochemical performance of supercapacitors mainly depends on the performance of electrode materials. Among them, activated carbon ...
