Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistented with the present invention.On the contrary, they be only with it is such as appended
The example of device and method being described in detail in claims, some aspects of the invention are consistent.
Electromagnetic radiation is called electronic smoke, is the phenomenon that energy is emitted to space with electromagnetic wave, electronics and information industry
Fast development, be greatly promoted the universal of wireless telecom equipment and high-frequency electron device, also result in the electricity got worse
Magnetic disturbance and electromagnetic pollution not only interfere the normal work of electronic component, and potential health danger can be also caused to human body
Evil, electromagenetic wave radiation are listed in the fourth-largest pollution sources after water source, atmosphere, noise, long-term excessive electromagnetic radiation meeting pair
Human body reproduction, nerve and immune system etc. damage.
Electromagnetic shielding material can absorb the electromagnetic wave issued with reflective electron equipment to a certain extent, be developed
A variety of electromagnetic shielding materials are to eliminate electromagnetic pollution, and traditional electromagnetic shielding material uses the metals such as copper, aluminium to manufacture more, high density
It is limited in the application of the multiple fields such as movable equipment, wearable electronic product and physical protection, Qi Taru with large volume
Nickel cobalt metallic fiber is overlying on to paraffin based composites, the carbonization silicon sponge, graphene-dimethyl silicone polymer of biological Carbon fibe
Composite sponge, it is big that there are density, using the wide disadvantage of thickness, therefore, develops light, high tenacity and the strong electromagnetic screen of machinability
Covering material and product will be with important research significance and practical application value.
