We present a simple and rapid method to spatially pattern the surface wetting properties of PDMS microfluidic devices by layer-by-layer (LbL) deposition of polyelectrolytes using syringe-vacuum-induced segmented flow in nonplanar geometry. Our technique offers selective surface modification in microfluidic chips with multiple flow-focusing junctions, enabling production of monodisperse double- and triple-emulsion drops.
我们提出了一种简单而快速的方法，通过在非平面几何形状中使用注射器-真空诱导的分段流，通过层层（LbL）沉积聚电解质来对 PDMS 微流控器件的表面润湿性进行空间图案化。我们的技术为具有多个流聚焦结的微流控芯片提供了选择性的表面修饰，从而能够生产单分散的双乳液和三乳液液滴。
