Abstract

The invention relates to a microwave absorbent based on synergistic coupling protection and a preparation method thereof. The preparation method takes ferrite fiber as a carrier to load barium titanate nanoparticles and comprises the following specific preparation steps that metal salt and polyvinylpyrrolidone are dissolved in an ethanol solution, and the ferrite fibers are prepared through a sol electrospinning charge high-temperature calcination technology; and soluble barium salt and tetrabutyl titanate are added into an organic solvent, a surfactant is added, and solvothermal reaction is conducted at 150-180 DEG C to obtain the ferrite and barium titanate composite fiber material. The preparation method has the characteristics of wide raw material source, low cost and excellent performance, the preparation technology is simple and easy to control, and industrial production is easy to realize.

Description

technical field

[0001] The invention relates to the field of preparation of inorganic nanomaterials, in particular to a microwave absorber based on cooperative coupling protection and a preparation method thereof. Background technique

[0002] The rapid development of wireless communication and electronic technology has promoted the widespread application of electronic equipment in military and civilian fields, and the harm caused by electromagnetic radiation and electromagnetic interference has attracted increasing attention from the society. In order to solve this problem, the attenuation and absorption of electromagnetic waves through microwave absorbing materials is the most ideal method, which has received extensive attention. Microwave absorption is the absorption and attenuation of incident energy through energy conversion and multiple scattering. In order to improve the electromagnetic wave absorption performance of the absorber, two key factors must be considered. ...
