由熱處理法製備導電性聚丙烯腈薄膜及其應用在電磁波干擾遮蔽

Preparation of Conductive Polyacrylonitrile Films via Heat Treatment for Electromagnetic Interference Shielding

摘要


本研究利用熱處理法將聚丙烯腈薄膜中的銀離子還原成銀形成金屬化導電性薄膜,經由四端子方法量測薄膜表面電阻之變化,還原後的薄膜,其表面電阻約為10^0~10^2Ω/cm^2左右,藉由電磁波遮蔽效果的測試結果在30-1500MHz下,其值可達30dB以上,可以吸收或反射掉99.9%電磁波。

並列摘要


The silver ions in the PAN metal chelate can be easily reduced to silver by heat treatment. The surface resistivity of these reduction films were measured according to the conventional four-terminal method and exhibited excellent surface resistivity around 10^0~10^2Ω/cm^2. The shielding effectiveness of interference of these reduction films can be reached above 30dB between 30-1500MHz. At this level, 99.9% extraneous radiation is either reflected or absorbed by these reduction films.
