中文摘要：
随着手机、电脑、电视等广泛应用于生活和工作中,电磁辐射日益严重,而电磁辐射危害人体健康且影响精密电子设备的运行.为了解决上述问题,以棉机织物为基布,以吡咯为单体,采用原位聚合法制备具有良好吸波性能的柔性聚吡咯涂层棉复合材料,探讨了吡咯浓度对复合材料介电常数实部、虚部、损耗角正切、表面电阻的影响,并对其外观形貌进行了研究.研究表明：吡咯浓度对聚吡咯涂层棉复合材料介电常数实部、虚部、损耗角正切、表面电阻影响较大;吡咯浓度为0.6 mol/L时,聚吡咯涂层棉复合材料的介电常数实部和虚部均最大,吡咯浓度为0.4 mol/L时,聚吡咯涂层棉复合材料损耗角正切值最大.
英文摘要：
With the wide application of mobile phone, computer, TV and so on in life and work,electromagnetic radiation is increasingly serious. Electromagnetic radiation causes serious damage to human health and affects the operation of sophisticated electronic equipment. The polypyrrole coated cotton composites with good wave absorption performance were produced using pyrrole as monomer by in-situ polymerization on cotton fabric. Firstly,the influence of concentration of pyrrole on the dielectric constant,dielectric loss,and surface resistance of composites were discussed. Secondly,exterior morphology was analyzed. The results showed that the concentration of pyrrole have great influence on the dielectric constant,dielectric loss,and surface resistance of the composite material. When pyrrole concentration was 0. 6 mol / L,the dielectric constant real part and imaginary part of the polypyrrole coated cotton composites was the maximum. When pyrrole concentration was 0. 4 mol / L,the loss tangent value of the polypyrrole coated cotton composites was the maximum.
