Abstract

Developing a slippery lubricant-infused porous surface (SLIPS) is an important strategy for fabricating dynamically omniphobic surfaces. In this study, biocompatible and non-toxic liquid silicone rubber, TiO nanoparticles, and dimethyl silicone oil were used to fabricate a SLIPS. Subsequently, systematic investigation was conducted to explore its associated properties and address existing challenges in this field. The chosen lubricant exhibited a strong chemical affinity towards the substrate, eliminating the need for any functionalization treatment prior to infusion. In addition, the fabricated SLIPS exhibited excellent dynamic omniphobicity as well as shear stability, thermal stability, chemical stability, and mechanical stability. Moreover, it demonstrated good self-cleaning performance for droplets, with varying surface energies, temperatures, and pH values, as well as for common dyes and contaminants. In addition, damage from external forces could self-repair on the SLIPS, which is beneficial for extending the service life and application range.

摘要

开发一种注入润滑剂的光滑多孔表面(SLIPS)是制造动态全憎表面的重要策略。在本研究中,使用生物相容性和无毒的液态硅橡胶、TiO纳米颗粒和二甲基硅油来制造SLIPS。随后,进行了系统研究以探索其相关性能并解决该领域现有的挑战。所选用的润滑剂对基材表现出很强的化学亲和力,无需在注入前进行任何功能化处理。此外,制造的SLIPS表现出优异的动态全憎性以及剪切稳定性、热稳定性、化学稳定性和机械稳定性。而且,它对具有不同表面能、温度和pH值的液滴以及常见染料和污染物表现出良好的自清洁性能。此外,外力造成的损伤在SLIPS上能够自我修复,这有利于延长使用寿命和扩大应用范围。
