Fabrication of Polydimethylsiloxane films with special surface wettability by 3D printing
Abstract(#br)Special wettability of biological surfaces usually depends on the unique micro-structures and surface chemistry natures. However, current preparation methods often involve complex processing steps or expensive moulds and have the limited ability to simulate these ordered and elaborate micro-structures. Herein, we report a facile and mould-free approach to fabricate special wetting surfaces by patterning an ordered porous structure with various geometric parameters via one-step 3D printing of Polydimethylsiloxane (PDMS) ink.
