防电磁辐射聚吡咯/棉织物的制备及其性能
|
摘要
为获得具备吸波特性的防电磁辐射织物,采用液相化学氧化法制备聚吡咯/棉高分子涂覆类织物,借助法兰同轴法测试织物电磁屏蔽效能,运用KES织物风格仪分析织物物理力学性能,在综合考察制备工艺对织物电磁屏蔽效能的影响以及织物经吡咯处理后的风格变化的基础上,获得最优制备工艺参数。同时,分析了织物电导率、厚度、电磁波频率以及表面孔洞面积对聚吡咯/棉复合织物电磁屏蔽效能的影响。在此基础上,建立了聚吡咯/棉复合织物及表面具有孔洞的复合织物的电磁屏蔽效能预测模型。结果表明:随着织物电导率、厚度的增加,屏蔽效能随之增加;随着电磁波频率的增加,电磁屏蔽效能呈现下降趋势;孔洞大小对电磁屏蔽效能影响显著。
In order to obtain anti-electromagnetic radiation fabric with wave-absorbing characteristics,the polypyrrole/cotton fabrics were fabricated by in situ polymerization. Based on the analysis on the influence of the preparation parameters on the electromagnetic shielding effectiveness( EMSE) tested by the flange coaxial method and the style of the fabric analyzed by KES-FB system,the optimum process parameters were obtained. Meanwhile,the influence of fabric conductivity,thickness,electromagnetic frequency and surface hole area on the EMSE of polypyrrole/cotton composite fabric was analyzed. The EMSE prediction model of polypyrrole/cotton composite fabric and the fabric with holes in the surface is established. The results show that with the increase of the conductivity and the thickness,the EMSE of the composite fabric increases,and the EMSE presents a falling tendency with the increase of the frequency of electromagnetic wave. The aperture size has remarkable influence on the EMSE of fabrics.
