Description
Technical field
The invention belongs to absorbing material technical fields, and in particular to a kind of efficient wave absorbing agent for 2~18GHz frequency range and
Preparation method.
Background technique
The high speed development of current electromagnetic wave technology, electronic equipment is ubiquitous in people's lives, brings a large amount of
Electromagnetic interference and pollution seriously threaten the health of people；And militarily, modern war is exactly an information war,
For the catbird seat occupied in war, the stealth technology for improving weaponry is extremely urgent.It is exactly currently with most
2~18GHz of centimeter wave, therefore developing the efficient wave absorbing agent of a kind of " thin, light, wide, strong " in the wave band is one extremely important
Task.
Fe3O4It is in ferrimagnetism, since dielectric loss with higher and magnetic loss are extensive with inverse spinel structure
Be applied to absorbing material, but single-phase Fe3O4The problems such as absorbing material thickness is larger and stability is poor is not able to satisfy existing
For the requirement of absorbing material.Therefore, Fe3O4The compound absorbing material of base becomes the emphasis of people's research.It is well known that in addition to
Outside the intrinsic properties of material itself, pattern is also an important parameter for influencing Absorbing Materials.The spherical pattern of nanometer has
Helping to improve electromagnetic wave by increasing specific surface area enhances the absorption to electromagnetic wave in internal multiple reflections；And nano bar-shape
Pattern is then conducive to the transmission of electronics, and material internal is made to form conductive network easily to enhance dielectric loss.Using nanosphere and receive
The Fe that rice stick coexists3O4/ Cu compound is as absorbing material, on the one hand, the pattern that nanosphere and nanometer rods coexist combines
The above nanosphere and nanometer rods advantage.On the other hand in addition to can use Fe3O4Itself dielectric loss and magnetic loss and Cu's
High conductivity is lost outside electromagnetic wave, can also utilize Fe3O4The space charge of heterogeneous interface gathers the interface to be formed between Cu
Loss is to enhance the absorption to electromagnetic wave.Absorbing property is improved by the combination of more loss mechanisms.
However, to obtain nanosphere and Fe that nanometer rods coexist3O4/ Cu compound, the Fe for needing accurate control to be added3+/
Cu2+Molar ratio.In fact, in forming process, if Fe3+/Cu2+Molar ratio is excessive, Cu2+Fe can mainly be entered3O4Lattice in
To replace Fe2+Ion forms single-phase Cu2+Adulterate Fe3O4.Only work as Fe3+/Cu2+When molar ratio is reduced to OK range, into
Enter Fe3O4Cu2+It reaches capacity, can just start to generate simple substance Cu, obtain Fe3O4/ Cu composite material.Also, when Cu simple substance is in body
When reaching a certain concentration in system, Fe can be become3O4Nucleation point, be conducive to crystal grain a direction forming core and grow up, promote part
Nanosphere changes to nanometer rods, the Fe that finally acquisition nanosphere and nanometer rods coexist3O4/ Cu compound.And if Fe3+/Cu2+Mole
Magnetic phase Fe than too small, in system3O4Content is very few, can cause being greatly reduced for system magnetic loss, seriously destroy impedance matching
Situation will be unfavorable for the raising of absorbing property.Therefore, excellent absorbing property is obtained in 2~18GHz frequency range, be critical to essence
The really Fe that control is added3+/Cu2+Molar ratio.
