It is mixed into particle in Molecularly Imprinted Polymer solution, and carries out a moulding process, to allow macromolecule polymer solution to form polymer thin film, and
The thickness of each polymer thin film is the electromagnetic wavelength integral multiple to be absorbed, finally in the side of high molecular polymer film
Reflecting layer of the refractive index more than the refractive index of composite layer is formed on face, to form electromagentic wave absorption film structure.But this side
Case is that more dustless environment is required to fall into Polymer Solution to prevent impurity or tiny micronic dust in technique, and high molecular polymer
The problem of being easy environment and devil liquor recovery in processing.
The prior art " for electromagnetic shielding composition, electromagnetic screen, anti static device and electromagnetic armouring structure it
Preparation method " (Republic of China's patent No.:I445018) tie up to a mixing material and be mixed into nanometer metal wire rod, with object it
The film of electromagnetic shielding is formed on surface.Only this scheme disadvantage is that the requirement to technologic technology and equipment is extremely harsh,
So that manufacturing cost is high.
In conclusion preferable effectiveness can be had under radio frequency environment and have both technique just by how providing one kind
The technical issues of electromagnetic shielding material of profit is this field urgent need to resolve.
