设计了一种全新的乳液聚合法,并结合自下而上的模板辅助电化学沉积方法制备了大面积有序周期常数为135nm的金属银双渔网结构超材料。新的制备方法在纳米颗粒经过预处理后,依然能够保持优良的单分散型,易于获得高质量的大面积纳米级二维胶体晶体模板,并且电磁谐振现象明显增强。
A novel method of emulsion polymerization was designed, and combined with electrochemical deposi tion to fabricate large-area green band double fishnet metamaterials. After pretreatment to clear away the re dundant reagent, this polystyrene emulsion still keep good monodispersion, and can be used to obtain good tem- plate of two-dimension colloidal crystal. We find that the double fishnet structures' electromagnetic resonance have been enhanced through experimental.
