Splet01. jan. 2024 · In this paper, we demonstrate that hydrophobic property of polydimethylsiloxane (PDMS) was modified with oxygen plasma at varying times. Then, PDMS was characterized by different surface techniques including surface roughness and contact angle. Optimum oxygen plasma treatment time induced hydrophilicity between … SpletHere we present a novel surface modification method based on the sequential layer-by-layer deposition of polyelectrolytes yielding hydrophilic microchannels in PDMS-based microfluidic devices. The coatings are long-term stable and allow for the generation of monodisperse oil-in-water microdroplets even several months after the channel surface …
