We investigated a facial method to produce silver nanowires with low aspect ratio by fragmentizing as produced long silver nanowires. The length of silver nanowires can be shortened in a controllable manner by increasing ultrasonication time or ultrasonication power. However, excessively large ultrasonication power caused a problem of agglomeration of nanowires. From UV absorption spectra, it was found that the UV absorption characteristic of silver nanowires is not affected by ultrasonication assisted fragmentation indicating that one dimensional structure of silver nanowires is maintained during the fragmentation process.
我们研究了一种通过将生成的长银纳米线碎片化来制备低纵横比银纳米线的方法。通过增加超声处理时间或超声处理功率，可以以可控的方式缩短银纳米线的长度。然而，过大的超声处理功率会导致纳米线团聚的问题。从紫外吸收光谱可知，银纳米线的紫外吸收特性不受超声辅助碎片化的影响，这表明银纳米线的一维结构在碎片化过程中得以保持。
