【摘要】：目的选用不同溶剂和基底进行纳米银线扫描电镜样品制备,探讨不同制样溶剂及基底对纳米银线扫描电镜观测的影响。方法选用去离子水和乙醇作为纳米银线的分散剂,样本充分混匀后,分别滴加在盖玻片和云母片上进行制样,用扫描电镜观察效果。结果以去离子水对样品进行分散,盖玻片为基底的制样方法,纳米银线出现成片的聚积和重叠。而采用乙醇为分散剂,云母片为基底进行制样时,纳米银线分散均匀,易于外部形貌的观测。结论选择乙醇为溶剂,云母片为基底,制样方便快捷,能够获得理想的扫描电镜观测效果。
[Abstract]:Objective to prepare nano-silver wire scanning electron microscope samples with different solvents and substrate, and to explore the effect of different preparation solvents and substrate on nano-silver wire scanning electron microscope observation. Methods deionized water and ethanol were used as dispersing agents for silver nanowires. After the samples were fully mixed, the samples were dripped on the cover slide and mica sheet for sample preparation, and the effect was observed by scanning electron microscope (SEM). Results the sample was dispersed with deionized water and covered with glass as the substrate, and the silver nanowires accumulated and overlapped. When ethanol is used as dispersing agent and mica sheet as substrate, the nano-silver wire is dispersed uniformly and is easy to observe the external morphology. Conclusion using ethanol as solvent and mica tablet as substrate, the sample preparation is convenient and rapid, and the ideal observation effect of scanning electron microscope can be obtained.
