A process that leverages capillary interactions between oligomers in an elastomeric polydimethylsiloxane substrate and deposited Ga enables the formation of Ga nanodroplets with nanoscale gaps in a single step. Gap-plasmon resonances excited within the nanogaps give rise to structural colours that can be tuned by changing the oligomer content in the substrate or by mechanical stretching.

通过毛细管相互作用制备机械致变色镓纳米结构

利用弹性体聚二甲基硅氧烷基底中的低聚物与沉积的 Ga 之间的毛细管相互作用的过程能够在一步中形成具有纳米级间隙的 Ga 纳米液滴。纳米间隙内激发的间隙等离子体共振产生结构颜色，可以通过改变基材中的低聚物含量或通过机械拉伸来调节结构颜色。
