氧化剂种类、温度、时间对聚苯胺/棉复合吸波材料介电性能的影响

Effects of Types of Oxidizing Agent,Temperature,Time on the Dielectric Properties of Polyaniline/Cotton Composite Absorbing Materials

探讨了氧化剂种类、温度、时间对聚苯胺/棉复合吸波材料介电性能的影响。结果表明:过硫酸铵对应的介电常数实部、虚部最大;三氯化铁、氯化铜、双氧水对应的介电常数实部、虚部较小。室温对应的介电常数实部和虚部最大。反应时间2.5h对应的介电常数实部和虚部最大,即反应时间为2.5h制得的复合材料对电磁波的极化能力和损耗能力最强。

Effects of types of oxidizing agent,temperature,time on the dielectric properties of polyaniline/cotton composite absorbing materials were discussed. The results showed that values of real and imaginary parts of the dielectric constant corresponding the ammonium persulfate were the largest; values of real and imaginary parts of the dielectric constant corresponding Iron(III） chloride,copper chloride and hydrogen peroxide solution were relatively smaller. Values of real and imaginary parts of the dielectric constant corresponding the ambient temperature were the largest. Values of real and imaginary parts of the dielectric constant corresponding the reaction time of 2. 5 h were the largest,namely,the polarization and loss abilities of the obtained composites were the strongest when the response time was 2. 5 h.
