可以承受大变形的柔性装置最近引起了广泛的兴趣。在本文中，我们研究了皱纹Au/PDMS薄膜的几种应变相关性质。我们发现，由于类Cassie-Baxter态到Wenzel态的转变，Au/PDMS上存在应变诱导的疏水到亲水转变。我们观察到，Au/PDMS还表现出与应变相关的表面增强拉曼散射行为以及良好的导电性和稳定性，并且可以承受∼30%的拉伸应变长达100个循环。该方法简单、通用、可行，对电子器件、自清洁、微流控、集水、应力监测等柔性元件的设计和制造具有一定的参考价值。
Flexible devices that can sustain large deformations have recently attracted widespread interest. In this paper, we investigate several strain-dependent properties of wrinkled Au/PDMS films. We discover a strain-induced hydrophobic to hydrophilic transition on Au/PDMS due to the transition from the Cassie-Baxter-like state to the Wenzel state. We observe that the Au/PDMS also exhibits strain-dependent SERS behaviours and excellent electrical conductivity and stability and can sustain a tensile strain of ∼30% for up to 100 cycles. This method is simple, general and feasible, which may be beneficial for the design and fabrication of flexible units for electronic devices, self-cleaning, microfluidic devices, water collection, and stress monitoring.
