Coordinated Silicon Elastomer Coating@fabrics with Oil/Water Separation Capabilities, Outstanding Durability and Ultra-fast Room-temperature Self-healing Ability

Abstract

Coating@fabrics with self-healing hydrophobic properties for oil/water separation have attracted significant attention. However, currently used self-healing coating@fabrics only enable the recovery of surface properties of the coating on fabrics. If the coating gets seriously damaged from interior (i.e., torn apart), the recovery of oil/water separation performance becomes difficult. In this study, a novel strategy to achieve self-healing ability based on the coating materials with reversible dynamic bonds was proposed. To develop this idea, a self-healing silicon elastomer cross-linked via cobalt (Co)-based coordination was coated on polyethylene terephthalate (PET) fabrics. The as-modified fabrics exhibited hydrophobic property with contact angle (CA) of >140, high oil/water separation factor of around 99%, high durability (even at extremely low temperatures), as well as ultra-fast self-healing ability at room temperature. After being damaged under extreme environment such as violent rubbing and/or beating when immersed in liquid nitrogen, the modified fabrics still exhibited fast self-healing properties (healing time was just 10 min) and high oil/water separation efficiency of nearly 99 %. Thus, this study proposes a novel design concept for fabrication of coating@fabrics with outstanding self-healing efficiency to recover oil/water separation performance at room temperature, and may pave a path for the development of an efficient family of self-healing fabrics.
