A new kind of high-quality Ag/PS coaxial nanocables can be facilely synthesized by using soft/hard templates method. In order to effectively introduce Ag sources into porous polystyrene (PS) nanotubes which were trapped in porous anodic aluminum oxide (AAO) hard template, Pluronic F127 (F127) was used as guiding agent, soft template and reductant. Meanwhile, ethylene glycol solution was also used as solvent and co-reducing agent to assist in the formation of silver nanowires. The influences of concentration of F127 and reducing reaction time on the formation of Ag/PS coaxial nanocables were discussed. Results indicated that the high-quality Ag/PS coaxial nanocables can be obtained by the mixed mode of soft/hard templates under optimized conditions. This strategy is expected to be extended to design more metal/polymer coaxial nanocables for the benefit of creation of complex and functional nanoarchitectures and components.
通过软/硬模板法可以轻松合成一种新型的高质量Ag/PS同轴纳米电缆。为了将Ag源有效地引入被困在多孔阳极氧化铝（AAO）硬模板中的多孔聚苯乙烯（PS）纳米管中，使用了Pluronic F127（F127）作为导向剂、软模板和还原剂。同时，乙二醇溶液也用作溶剂和共还原剂以协助银纳米线的形成。讨论了F127浓度和还原反应时间对Ag/PS同轴纳米电缆形成的影响。结果表明，在优化条件下通过软/硬模板的混合模式可以获得高质量的Ag/PS同轴纳米电缆。该策略有望扩展到设计更多的金属/聚合物同轴纳米电缆，以利于创建复杂的功能性纳米结构和组件。
