Abstract

The invention relates to a copolymer, particularly a copolymer with electric storage characteristics. The copolymer is formed by copolymerizing a monomer X and a monomer Y, wherein the monomer X is a carbazolyl group, and the monomer Y is an azo group; the mass percent of the monomer X is 30-90%, and the mass percent of the monomer Y is 10-70%; and the number-average molecular weight of the copolymer is 5000-15000. The invention also relates to a method for preparing the copolymer. The invention also relates to an electric storage device prepared from the copolymer and a preparation method of the electric storage device. The copolymer with electric storage characteristics and the electric storage device prepared from the copolymer can implement binary storage, have excellent stability, provide more options for large-scale application of organic electric storage materials and devices, and solve the problems of fewer varieties of electric storage materials and poor effects at present to some extent.

Description

technical field [0001] The invention relates to a copolymer, in particular to a copolymer with electrical storage properties and a preparation method thereof. [0002] The invention also relates to an electric storage device prepared by using the copolymer, and a preparation method of the electric storage device. Background technique [0003] Traditional information storage methods mainly use inorganic silicon semiconductor materials. However, due to the high production cost of silicon and other inorganic materials, complex processes, and the inability to manufacture large areas, they cannot meet the needs of today's society for information storage. So it motivates us to look for materials with lower cost, which can be manufactured in large area and have higher information storage capacity. Compared with silicon devices that record data by marking "0" and "1" states, the data storage of organic electrical memory devices is a new mode, which changes organic materials from a ...
