全憎表面在各个领域都有着广泛的应用，并引起了人们的广泛关注。特别地，将全憎性应用于预包装食品（例如咖喱）的容器对于减少食物浪费是极其重要的，因为它们由于其高粘度而特别容易保留在容器中。为了实现这种应用，表面必须是生物相容的，以防止对人体的健康损害。然而，很少有具有生物相容性的全憎性表面被开发出来。在这里，我们提出了一种硅油固定的生物相容性与全憎性滑表面。通过热处理将勃姆石纳米结构和硅油接枝结合，制备了生物相容性基底层以将硅油作为润滑剂。光滑的表面不仅对室温液体而且对高温液体包括热的液体食品表现出全憎性。此外，该表面表现出长期稳定性，在热水中沸腾。而且，表面可以在一个小时内制造出来。我们相信，由于其优异的生物相容性和全憎性，这种表面不仅适用于食品容器，还适用于各种其他应用。
Omniphobic surfaces have attracted much attention and have a lot of applications in various fields. In particular, the application of omniphobicity to containers of prepackaged foods such as curry is extremely important for reducing food waste because they are especially liable to remain in the container owing to their high viscosity. To realize such application, the surface must be biocompatible to prevent health damage to the human body. However, few omniphobic surfaces with biocompatibility have been developed. Here, we present a silicone oil-immobilized biocompatible slippery surface with omniphobicity. A biocompatible base layer to immobilize the silicone oil as a lubricant was fabricated by combining a boehmite nanostructure and silicone oil grafting through thermal treatment. The slippery surface demonstrated omniphobicity not only for room temperature liquids but also for high-temperature liquids including hot liquid foods. In addition, the surface exhibited long-term stability against boiling in hot water. Moreover, the surface could be fabricated within an hour. We believe that because of its excellent biocompatibility and omniphobicity, this surface will be applied to not only food containers but also various other applications.
