摘　　要：为制备轻质高效的吸波型电磁屏蔽织物,采用层层组装方法在棉织物表面涂层氧化石墨烯/聚苯胺(GO/PANI)电磁屏蔽功能膜。研究苯胺单体浓度、氧化石墨烯质量浓度、组装层数对整理棉织物电性能及电磁屏蔽性能的影响,并分析了屏蔽电磁能的吸收率、反射率以及吸收屏蔽效能和反射屏蔽效能。结果表明:苯胺单体浓度和组装层数的增加有利于提高棉织物的电磁屏蔽效能,而随着氧化石墨烯质量浓度的增加,织物的电磁屏蔽效能先增加后减小;组装4层GO/PANI功能膜后棉织物的屏蔽效能达到19.91dB,可屏蔽98.98%的电磁能,其吸收率达到57.63%,而反射率为41.35%,主要屏蔽机制是吸收。In order to prepare lightweight and efficient electromagnetic shielding fabric of absorption-type, a graphene oxide (GO)/polyaniline (PANI) functional film was coated on cotton fabric using layer-by-layer assembling method. The influences of the concentration of aniline (AN) monomer, the concentration of GO and the number of assembly layers on the electrical properties and electromagnetic shielding properties of cotton fabrics were studied. The absorptivity, reflectivity, and shielding effectiveness due to absorption and reflection were analyzed. The results show that the increase of AN concentration and the number of assembling bilayer improve the electromagnetic shielding effectiveness of the fabric, but with the increase of GO concentration, the shielding effectiveness value of the fabric increases first and then decreases, the shielding effectiveness of fabric with 4 bilayers of GO/PANI reaches 19.91 dB, which could shield 98.98% of electromagnetic energy, the absorptivity of the fabric is 57.63%, and the reflectivity is 41.35%, the main shielding mechanism is absorption.
