Organic polymeter as electromagnetic shielding material and its prepn process

Abstract

The organic polymer as electromagnetic shielding material and its preparation process belongs to the field of material science and technology. The organic polymer as electromagnetic shielding material has organic polymer of polymerization degree n of 20-400 in the shown structure as the main component. It is prepared with the monomer with aniline and ferrocene as main material, and through slowly dropping oxidant solution into the monomer solution to polymerize and adding proper amount of dopant. The polymer has in its molecular structure polyaniline as the conducting mother substance and ferrocene as the magnetic radical, so that it has both electric conductivity and magnetism. It has high comprehensive shielding effect, low density, wide applicable frequency range, low temperature coefficient, low magnetic loss and other excellent characteristics, and may find wide application in electromagnetic shielding, wave absorption, etc.

At the same time, the pollution of electromagnetic waves to human working and living environments has become a serious social problem, threatening human health, and the leakage of electromagnetic radiation often leads to failure of automatic control systems. Risk of misoperation and information theft. [0003] In order to effectively suppress the radiation, leakage and...

AI Technical Summary

Problems solved by technology

However, they all have the disadvantage of low overall shielding effectiveness.

The reason is that they can only adjust certain influencing factors in the electromagnetic shielding material alone, but cannot adjust the two decisive parameters of electrical conductivity and magnetic permeability at the same time.

At the same time, metals and magnetic ferrites still have shortcomings such as heavy weight, high loss, difficult implementation, and poor regeneration potential, which cannot adapt to the development direction of miniaturization, light weight, and high frequency of electronic devices

Although conductive polymers have overcome the shortcomings of metal materials and magnetic ferrites to a certain extent, they still have problems of poor processability, poor stability, insufficient conductivity, and high prices. It is very difficult to adjust the shielding effectiveness
