摘要
采用平纹纯棉织物为基布,聚氨酯为粘结剂,通过涂覆的方法制备ZnO/Fe_(3)O_(4)复合涂层织物。研究不同涂料种类对涂层织物电磁屏蔽性能的影响,分别使用X射线衍射仪、扫描电子显微镜和矢量网络分析仪对样品的物相结构、微观形貌和屏蔽性能进行了测试。结果表明由于介电损耗和磁损耗的协同效应,ZnO/Fe_(3)O_(4)复合涂层织物在X波段(8.2~12.4 GHz)内显示出较好的电磁屏蔽性能,屏蔽效能SE最高可达10.98 dB,最佳SSE/t值为256.5 dBcm^(3)/g。
Using plain cotton fabric as base cloth and polyurethane as binder,ZnO/Fe_(3)O_(4)composite coated fabrics are prepared by a coating method.The influence of different coating types on the electromagnetic shielding properties of coated fabrics is studied.And X-ray diffractometer,scanning electron microscope and vector network analyzer are used to test the phase structure,microscopic morphology and shielding performance of the samples respectively.The results show that the ZnO/Fe_(3)O_(4)composite coated fabrics exhibit good electromagnetic shielding performance in X-band (8.2~12.4 GHz) due to the synergistic effect of dielectric loss and magnetic loss.The shielding efficiency SE reaches up to 10.98 d B,and the optimal SSE/t value is 256.5 d Bcm^(3)/g.
