Abstract

The present invention relates to a copolymer, in particular to a copolymer with electrical storage properties, which is formed by copolymerization of monomer X and monomer Y, monomer X is a carbazole group, and monomer Y is an azo group ; The mass percentage of monomer X is 30%-90%, and the mass percentage of monomer Y is 10%-70%; the number average molecular weight of the copolymer is 5000-15000. The invention also relates to a process for preparing the copolymer. The invention also relates to an electric storage device prepared by using the copolymer, and a preparation method of the electric storage device. The copolymer with electrical storage characteristics of the present invention and the electrical storage device prepared by the copolymer can realize binary storage and have excellent stability, and the large-scale application of organic electrical storage materials and devices provides more choices. To a certain extent, it solves the problem that the types of materials currently available for electrical storage are relatively small and the effect is not ideal.

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 ...
