Problems solved by technology

However, due to the limitations of the above methods, for example, the thermal evaporation method has high energy consumption and low controllability; the process flow of the external force-assisted method is cumbersome; Non-equilibrium morphology due to solvent volatilization or film thermal effect resulting in rapid quenching, which is not conducive to obtaining uniform nanofiber self-assembled fragments on the substrate
In addition, the above problems have brought great challenges to the preparation of large-area and homogeneous organic nanofibrous films.

Abstract

The invention belongs to the field of composite materials, and particularly relates to a celestite blue film composite material and a preparation method thereof.The preparation method comprises the following steps that celestite blue is dissolved in a mixed solvent, and a precursor solution for preparing a film is obtained; injecting the solution into an electrolytic tank, applying a direct-current voltage, and depositing a celestite blue material on a conductive electrode interface to obtain a layer of uniform nanofiber-shaped self-assembled film; and after vacuum drying, plating a layer of metal Al electrode on the surface of the functional material film as a top electrode, and taking a deposited conductive electrode as a bottom electrode to prepare the celestite blue film composite material. The preparation of the organic nanofiber self-assembled film is effectively realized by utilizing the functional group of the material and the external electric field acting force, the electrical property of the material is effectively improved, the storage effect based on electrical signal response is induced, and the preparation method has a reliable application prospect in the field of electric memories.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a lapis lazuli blue film composite material and a preparation method thereof. Background technique [0002] The 21st century is an era of science and technology. With the rapid development of society, people are more and more yearning for the convenient life brought by intelligence. However, behind the development of intelligence, on the one hand, it comes from the strong support of hardware equipment, and on the other hand, it depends on the rapid development of "big data" and its storage technology. The daily data processing volume in the current society is increasing geometrically, and society's requirements for memory are getting higher and higher. Therefore, data security, high efficiency, and large-capacity storage have become the vanguard of the "big data" era. And the electromechanical information storage materials and nano-devices with binary or even mult...
