摘要: 为研究PET非织造基银膜的结构及性能,在室温条件下,用磁控溅射法在PET非织造布基材上制备了25、50、75、100 nm4种不同厚度的Ag薄膜,由X射线衍射对薄膜微结构测试分析得知:制备的Ag薄膜均呈多晶态,晶体结构均呈面心立方;随着膜厚的增加,薄膜的平均晶粒尺寸逐渐增大。薄膜的光谱和导电性能测试表明:PET基银膜存在临界膜厚,在临界膜厚范围内,随着膜厚的增加,薄膜的反射率急剧增强,透射率快速下降,但达临界膜厚后,反射率和透射率随膜厚的变化趋于平缓;随着膜厚的增加,薄膜的导电性能明显提高。

Abstract: A series of silver coated PET nonwovens was prepared by magnetron sputtering at room-temperature, the corresponding thickness of silver film were 25, 50, 75 and 100nm, respectively. X-ray diffraction measurements were carried out to examine the morphology of the silver films, it was found that the silver films form polycrystalline, crystal structure forms face-centered cubic; the mean size of Ag particles enlarges with increasing of film thickness; the spectrum and electric properties were also measured, the results indicated that there exists critical value of silver films thickness. Below the critical thickness, the reflectivity increases sharply while transmission rate decreases with the increasing of film thickness; but the change of reflectivity and transmission rate tend to a stable value when the film thickness reached at the critical value. The four- point probe test shows that the conductivity increases evidently with film thickness increasing via measurement of conductivity.
