微細構造と親水性単分子修飾の組合せによる油滴除去機能面

This study introduces a method for making hydrophilic surface for oil-repellent function by the combination of chemical modification and surface texturing. Si-PEG monolayer was self-assembled on a silicon substrate ideally fixed with siloxane bonding. Conditions for Si-PEG modification and the effect of micro-pillar pitch on contact angle of oil in water were made clear. It was found that the high-contact angle of oil droplet in water on a structured and chemically modified surface lasted long time.
