Abstract

The invention discloses an electromagnetic shielding fabric based on ferroferric oxide / polypyrrole, a production method and application, and belongs to the technical field of electromagnetic shielding materials, and the design key points are as follows: for the problem of a flexible electromagnetic shielding material, ferroferric oxide nanoparticles are combined with pyrrole by using a composite nanoparticle production method, so that the flexible electromagnetic shielding material is obtained. The ferroferric oxide / polypyrrole magnetic shielding fabric is prepared from ferroferric oxide and polypyrrole, the ferroferric oxide / polypyrrole composite nano-particles are formed, meanwhile, the surface of textile base cloth is coated with the ferroferric oxide / polypyrrole composite nano-particles by combining and utilizing a coating finishing technology, and the ferroferric oxide / polypyrrole magnetic shielding fabric is formed. By the adoption of the electromagnetic shielding fabric based on ferroferric oxide / polypyrrole, the production method and the application, the good magnetic shielding effect is achieved in low-frequency magnetic shielding, and meanwhile the electromagnetic shielding fabric has flexibility and portability and is suitable for a portable magnetic shielding device.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic shielding materials, in particular to an electromagnetic shielding fabric based on ferric oxide / polypyrrole and a production method thereof. Background technique [0002] With the rapid development of modern science and technology and the popularization of various electronic devices, electromagnetic energy is inevitably radiated to the environment. Electromagnetic radiation can interfere with equipment, form electromagnetic leakage, and affect human health. How to reduce electromagnetic radiation, prevent electromagnetic leakage, and reduce electromagnetic radiation pollution is of great significance to national defense security and the protection of people's health. The research on electromagnetic shielding at home and abroad is mostly carried out on high-frequency electromagnetic shielding materials. The principle of high-frequency electromagnetic shielding is the eddy current effect. M...
