| 摘 要： | 尼龙织物经功能性高分子壳聚糖(CS)预处理后,应用分子自组装技术于其表面自组装钯膜(镀镍前活化).该膜钯微粒为纳米级,比表面较大,催化活性较高.将成膜后的织物化学镀镍磷合金,即可得到屏蔽性能优异的电磁屏蔽织物.正交试验及单因素试验得出CS预处理的最佳工艺条件.SPM、SEM表征活化前后及施镀前后织物表面的形态变化.根据Schelkunoff理论,计算织物的电磁辐射屏蔽效能,其值高于30 dB,相当于屏蔽掉了96.0%以上的电磁波.

| Abstract: | After the pretreatment of nylon fabric by functional chitosan,the self-assembly technique was used in the process of activation before electroless plating to produce the CS-Pd membrane.The nanosized palladium particles with nanoscal have large relative surface and high catalyzed activity.Electromagnetic wave shielding fabric was prepared by electroless plating of Ni-P alloy with the activated fabric.The optimal process condition of CS finishing was given with the orthogonal and single factor experiments.The... |
