摘要

Effects of the aniline concentration, concentration of oxidizing agent on the real and imaginary parts of the dielectric constant and the loss tangent of polyaniline /cotton composite absorbing materials were dis-cussed.The results showed that the effect of the aniline concentration on the polarization ability of composite ma -terials was larger;when the dosage of aniline reached a certain concentration,the real part of the dielectric con-stant appeared the peak value and decreased if the dosage increased.The effect of the aniline concentration on the electric magnetic wave dissipation capability of composite materials was larger; when the dosage of aniline reached a certain concentration, the imaginary part of the dielectric constant appeared the peak value and de-creased if the dosage increased.The effect of the concentration of oxidizing agent on the polarization ability of composite materials was larger;when the dosage of oxidizing agent reached a certain concentration,the real part of the dielectric constant appeared the peak value and decreased if the dosage increased.The effect of the concen-tration of oxidizing agent on the electric magnetic wave dissipation capability of composite materials was larger;when the dosage of oxidizing agent reached a certain concentration, the imaginary part of the dielectric constant appeared the peak value and decreased if the dosage increased.%探讨了苯胺浓度、氧化剂浓度对聚苯胺/棉复合吸波材料介电常数实部、虚部、损耗角正切的影响.结果表明:苯胺浓度对复合材料的极化能力影响较大,苯胺用量达到一定浓度,介电常数的实部出现峰值,继续增加用量,介电常数实部减小.苯胺浓度对复合材料的电损耗磁波能力影响较大,苯胺用量达到一定浓度,介电常数的虚部出现峰值,继续增加用量,介电常数虚部减小.氧化剂的用量对复合材料的极化能力影响较大,氧化剂用量达到一定浓度,介电常数的实部出现峰值,继续增加用量,介电常数实部减小.氧化剂的用量对复合材料的电磁波损耗能力影响较大,氧化剂用量达到一定浓度,介电常数的虚部出现峰值,继续增加用量,介电常数虚部减小.
