摘要： 以Fe3O4为磁损耗材料、聚吡咯为导电吸波材料，采用两步法制备了Fe3O4/聚吡咯/棉防电磁辐射复合织物。首先利用Fe3O4纳米分散液对棉织物浸轧、烘干方式获得Fe3O4/棉磁性复合织物，并以此为基底材料，以FeCl3为氧化剂、对甲苯磺酸为掺杂剂，通过原位聚合制备成磁性Fe3O4/聚吡咯/棉电磁屏蔽复合面料。探讨了吡咯单体浓度、氧化剂与掺杂剂浓度等因素对织物电磁屏蔽效能的影响规律，以及整理对棉织物吸濕速干性能的影响。实验结果表明，FeCl3·6H2O与C4H5N摩尔配比为1︰1，摩尔浓度为0.6mol/L时具有最佳的电磁屏蔽性能，在30～1500MHz内，电磁屏蔽效能值可达15dB，整理前后棉织物的液态水动态传递综合指数由5级降为2级，即整理削弱了棉织物的吸湿速干性能。

Abstract： Ferroferric oxide/polypyrrole（PPY）/cotton composite fabric was prepared with twostep process by taking Fe3O4 and PPY （polypyrrole） as magnetic loss material and wave absorption material respectively. Firstly， Fe3O4 nanodispersion solution was used to gain Fe3O4/cotton magnetic composite fabric by cotton fabric padding and drying. Fe3O4/cotton magnetic composite fabric was used as the substrate material， and FeCl3 and ptoluenesulfonic acid were used as the oxidant and dopant respective； by to prepare magnetic Fe3O4/PPY/cotton electromagnetic shielding composite fabric. The effect of dosages of oxidant， pyrrole and dopant on electromagnetic shielding property of the fabric was investigated in this study. Moreover， the influence of finishing on moisture absorption and quick drying performance of the cotton fabric was also studied. The result shows that the prepared EM shielding fabric has the best electromagnetic shielding property （15dB） in the frequency of 30-1500 MHz under the following conditions： mole ratio of FeCl3·6H2O to C4H5N 1︰1， pyrrole concentration 0.6 mol/L. The water dynamic transfer index of cotton fabric declined to Grade 2 from Grade 5 after finishing. In other words， the finishing weakens overall moisture absorption capability of cotton fabric.

随着现代电子设备小型化、高度集成化的迅猛发展，人类所处的电磁环境越来越复杂。大量科学证据表明，长期暴露在电磁辐射的环境下容易导致人体新陈代谢紊乱、身体免疫力下降、皮肤粗糙等，甚至诱发白血病及各类癌症[14]。为减少电磁波辐射危害，实现自我保护，各种电磁屏蔽材料的研发成为热点。在人体防护方面，穿着具有电磁屏蔽功能的服装是切实可行的。目前，防电磁辐射服装面料主要分为金属纤维混纺织物、金属涂层与导电高分子复合织物两大类。相对于金属复合织物而言，利用导电高分子织物设计制造的电磁防护面料在面料保形性、穿着舒适性、吸波特性等方面更具有优势[57]。……
