The reporter understands from Chinese academy of sciences hefei institute of material science, its application of advanced materials center scientists have developed a new type of electromagnetic interference resistance materials, shielding performance can achieve 56 db, up by more than 60% than ordinary materials. The relevant results are published in the science and technology of composite materials, and have authorized the national invention patent.
With the wide application of modern computer and communication technology, electromagnetic interference is becoming more and more serious. The development of high-performance electromagnetic shielding material has become the target of many materials researchers. Compared with traditional metal shielding materials, polymer composites have become a research hotspot in recent years due to their advantages of light weight, corrosion resistance, easy processing and electrical conductivity.
Hefei material science research institute of Chinese academy of sciences in the application of advanced materials by heart and friends researcher and deputy researcher zhang led research and development team, choose high electrical conductivity of multi-walled carbon nanotubes as functional materials, such as chemical corrosion resistance, high temperature resistant performance of poly (vinylidene fluoride as polymer matrix, adopt the method of hot pressing and etching a lightweight plank of nano composite is prepared. Due to its unique structure design, the material obtained excellent electromagnetic shielding performance.
