中文摘要：

采用通过“自下而上”的电化学沉积法制备纳米尺度的双层银树枝状结构,通过调节外加电压、沉积时间等实验参数,在第一层银树枝表面涂覆的PVA薄膜上成功生长一层随机分布、大小均一的银树枝结构单元,并利用SEM、分光光度计分别对该复合结构的形貌以及透射特性进行研究,实现了银树枝复合材料光频段透射增强和透射峰位置的可控调节.

英文摘要：

A kind of double-layer of silver dendritic structure at nanometer scale through the ＂bottom-up＂ electrochemical deposition method was prepared.By adjusting experimental parameters such as voltage,sedimentary time,a uniform random layer of silver dendritic thin film was fabricated on the first layer of silver dendritic cells coated with PVA membrane.Moreover,the morphology and visible transmission properties of the composite structure were investigated using SEM and UV-Vis-IR spectrophotometry,respectively.By varying experimental parameters,the enhancement of magnitude and tunability of the frequency of the transmission peak were achieved.
