新型柔性毫米波材料导电布的制备与测试

摘要

A fabrication method of a kind of new and flexible conductive substrate with millimeter wave ma-terial is inroduced. The metal coating is deposited on the surface of terylene substrate using the composite coat-ing technology of vacuum magnetic control sputtering. The conductive performance and coating adhesion of the conductive substrate are tested. And the millimeter radiation characteristics in 3 mm waveband between the con-ductive substrate and the metal aluminum board are tested by a millimeter wave radiometer testing system. The results show that the conductive coating is uniform, flexible, ethereal and thin and has good coating adhesion strength and stronger conductive performance. The millimeter wave radiation of conductive substrate in 3 mm waveband corresponds to the performance of metal board.%提出一种新型柔性毫米波材料导电布的制备方法，采用真空磁控溅射复合镀膜技术在涤纶基布表面沉积金属镀层。检验导电布的导电性能和镀层附着力，并应用毫米波辐射计测试系统测试导电布与金属铝板的3 mm波段毫米波辐射特性。结果表明，导电布镀覆均匀，质地柔软轻薄，有良好的镀层结合强度及较强的导电性能。导电布在3 mm波段的毫米波辐射与金属板的性能相当。
