Polydimethylsiloxane (PDMS) membranes are used in various applications, such as microvalves, micropumps, microlenses, and cell culture substrates, with various thicknesses from microscale to nanoscale. In this study, we propose a simple fabrication method for PDMS membranes on a water surface, referred to as the floating-on-water (FoW) method. FoW can be used to easily fabricate PDMS membranes with thicknesses of a few micrometers (minimum 3 μm) without special equipment. In addition, as the membrane is fabricated on the water surface, it can be easily handled without damage. In addition, alternative membrane structures were demonstrated, such as membrane-on-pins and droplet-shaped membranes. FoW can be widely used in various applications that require PDMS membranes with microscale thicknesses.
聚二甲基硅氧烷（PDMS）膜被用于各种应用中，如微阀、微泵、微透镜和细胞培养基质，其厚度从微米级到纳米级各不相同。在本研究中，我们提出了一种在水面上制备PDMS膜的简单方法，称为水浮法（FoW）。水浮法可用于轻松制备厚度为几微米（最小3μm）的PDMS膜，无需特殊设备。此外，由于该膜是在水面上制备的，因此可以很容易地处理而不会损坏。此外，还展示了其他膜结构，如针上膜和液滴形膜。水浮法可广泛应用于各种需要微米级厚度PDMS膜的应用中。
