We present a gram-scale synthesis of metallodielectric Janus matchsticks, which feature a gold-coated silica sphere and a silica rod. SiO2 Janus matchsticks are synthesized in one batch by growing amine-functionalized SiO2 spheres at the end of SiO2 rods. Gold deposition on the spheres produces Au–SiO2 Janus matchsticks with an aspect ratio controlled by the rod length. The metallodielectric Janus matchsticks, produced by scalable colloidal synthesis, hold great potential as functional colloidal materials.

金属介电Janus火柴棒的胶体合成

我们提出了一种克级合成的金属介电 Janus 火柴棒,其特征是镀金的二氧化硅球和二氧化硅棒。 SiO 2 Janus 火柴棒是通过在 SiO 2棒末端生长胺官能化的 SiO 2球体来批量合成的。球体上的金沉积产生了 Au-SiO 2 Janus 火柴棒,其纵横比由棒的长度控制。通过可扩展的胶体合成生产的金属介电Janus火柴棒作为功能性胶体材料具有巨大的潜力。
