Preparation Of Microwave Absorber With PANi-HBF₄and The Study Of Its Electromagnetic Properties

PANi is very potential in the field of microwave-absorbing material.Mixed with mineral acids,the conductivity of PANi could be much improved.PANi's got the less density and convenience of preparation.In the article,we study on the electromagnetic property of PANi-HBF4,and to prepare compound material with Ag,AgBF4and PEO.Then,to control the electromagnetic property by changing the potential on the material.PANi-HBF4has been prepared in many different conditions systematically.Among those,the sample on the condition that the mass ratio of An and APS is1:2,has the best electromagnetic property. Then detect the property of absorption from2to18GHz.To change the potential on the film to control the property of absorption as expect.
