Embodiment 1

[0038] 1) Preparation of methyl polyarylether sulfone (PAES-Me):

[0039]

[0040] 2-methylhydroquinone (HQ-Me), 4,4’-dichlorodiphenylsulfone (DCDPS) and potassium carbonate (K 2 CO 3) into a 250ml three-neck flask according to the molar ratio of 1:1:1, and nitrogen gas was introduced. Measure 100ml of sulfolane (TMS) and 50ml of toluene solution, pour it into a three-necked flask, use a spherical condenser and a water separator to build an experimental device, and install a stirring device. Adjust the temperature of the system to 150°C for three and a half hours, and use toluene to take out the water in the system; then raise the temperature and maintain it at 180°C to make 2-methylhydroquinone (HQ-Me) and 4, 4'-dichlorodiphenyl sulfone (DCDPS) fully polymerized. Observe the viscosity of the system. After about three and a half hours, the viscosity of the system remains stable, and the material starts to be discharged. During the discharging process, the product was po...

Abstract

The invention discloses a blend, a blend film and a preparation method thereof, and applications of the blend film in supercapacitors, and particularly relates to a method for preparing an electrolytefilm by blending polyaryl ether sulfone as a matrix and polyvinylpyrrolidone. The preparation method comprises: polymerizing 2-methylhydroquinone and 4,4'-dichlorodiphenyl sulfone to obtain methyl polyaryl ether sulfone, brominating the methyl polyaryl ether sulfone to obtain polyaryl ether sulfone with a bromomethyl functional group, dissolving polyvinylpyrrolidone and the brominated polyaryl ether sulfone through DMSO, and forming a blend film through a casting method so as to form a two-material blended blend film. According to the invention, the prepared blend film has good mechanical property and good ionic conductivity, and can be used as an excellent electrolyte film to be applied to supercapacitors.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a blend, a blend film, a preparation method thereof and an application in supercapacitors. Background technique [0002] With the rapid development of science and technology, environmental problems in modern times are becoming more and more serious, such as the greenhouse effect, soil erosion, water pollution and a series of problems affecting people's lives. A large part of the cause of pollution in today's world lies in waste materials produced by energy consumption. Among the traditional energy sources, the combustion of coal and the exploitation of oil have brought rapid growth to the modern economy, but at the same time, they have also led to the emergence of a series of modern environmental problems. Even batteries have caused a series of problems such as mercury poisoning. Therefore, for energy supply, the direction of green environmental protection has become an ...
