Abstract
Lubricant-infused textured surfaces have gained much attention as liquid-repellent surfaces owing to high surface stability compared to their superhydrophobic counterparts. In this study, polydimethylsiloxane (PDMS) micro-structures (width: 20 μm, height: 80 μm), were fabricated using soft lithography. Effects of micro-structural geometry, including pillar-Type (pillar, discrete ridge) and hole-Type (hole, continuous ridge, circular rings with eight stripe supporters), on infiltration capability of the lubricants with different viscosity (Krytox-103; η: 0.131 Pa.s, Krytox-105; η: 0.737 Pa.s, paraffin oil; η: 0.112 Pa.s) were investigated. Partial infiltration was observed on the pillar-Type micro-structures, while more completed infiltration was obtained on the hole-Type micro-structures. More viscous Krytox-105 resulted in completed infiltration for all micro-structures, thus creating a slippery liquid-infused porous surface (SLIPS). The best SLIPS, signified by a low sliding angle and a fast speed of water droplet, prepared from the hole pattern infused with Krytox-105 exhibited good anti-fouling performance against chlorophyll and milk yogurt. © 2021 The Japan Society of Applied Physics.
