摘要

我们报道了CF4/O2等离子体处理聚二甲基硅氧烷(PMDS)表面作为一种新方法，为镓基液态金属微流体创建本质上不湿润的表面。结果表明，CF4/O2等离子体在PDMS上沉积bbbb120s，产生纳米级的粗糙度，对液态金属具有不润湿性。采用镓基液态金属液滴等离子体处理的PDMS表面的静态接触角和接触角滞后(CAH)分别为bb0 144°和< 16.8°。采用15°斜面滚动试验验证了表面的非润湿性。

Plasma-Treated PDMS as Intrinsically Non-Wetting Surface for Gallium-Alloy Liquid Metal Microfluidics

We report the CF4/O2 plasma treatment of polydimethylsiloxane (PMDS) surface as a new method to create an intrinsically non-wetting surface for gallium-based liquid metal microfluidics. It was found that CF4/O2 plasma on PDMS for > 120s creates nanoscale roughness which exhibits a non-wetting property against liquid metals. Static contact angles and contact angle hysteresis (CAH) of the plasma-treated PDMS surfaces using gallium-based liquid metal droplets were found to be > 144° and < 16.8°, respectively. Rolling test with 15° inclined surfaces were used to confirm non-wetting property of the surface.
