Description
Technical field
The utility model belongs to technical field of electromagnetic shielding, more particularly to a kind of electromagnetic shielding material.
Background technology
With developing rapidly for hyundai electronicses electrical equipment, the harm that electromagnetic interference, electromagnetic exposure and electromagnetic radiation are brought
Increasingly severe, for example, electromagnetic interference causes radio communication, smooth, electronic performance does not decline and aircraft lifting and landing system down
Deng having a strong impact on life and the life security of people.Therefore the research of electromagnetic shielding material is increasingly paid close attention to by people, respectively
The electromagnetic shielding material of type various kinds is continued to bring out.
Traditional electromagnetic shielding material is mostly single layer of conductive shielding material, although single layer of conductive shielding material is simple, conveniently,
Production cost is low, but very limited to the shielding action of electromagnetism, it is impossible to effectively eliminate the influence of electromagnetic belt.Electromagnetic shielding material
Generally use metal material, such as copper, silver, platinum, but to there is expensive, oxidation, the density of being easily corroded big etc. for metal material
Shortcoming, seeks alternative materials and is particularly important.
Carbon nanomaterial (such as graphene, CNT, carbon nano-fiber) is due to the advantages of electric conductivity is excellent, intensity is big
Preferable conductive shielding material is become, but carbon nanomaterial specific surface area is big, surface free energy is big, easily rolls up
Bent, reunion, this limits its use in electromagnetic shielding material to a certain extent.
