Background
In recent years, the super-hydrophobic/oleophobic material has important application in daily life and has extremely wide application prospect in many fields such as national defense industry, medical health and the like. Super hydrophobic/oleophobic fabrics are becoming popular because of their special wettability properties, as well as their water, oil, stain, corrosion, icing and self-cleaning properties. Research shows that the micro-nano composite rough structure and low surface energy are key factors for forming the super-hydrophobic/oleophobic surface.
Based on this, many methods for preparing superhydrophobic/oleophobic surfaces have been proposed, such as layer-by-layer self-assembly, sol-gel, plasma techniques, electrochemical deposition, etching, phase separation, and templating. However, most of the methods have complicated processes, difficult process control, and need special equipment, and some of the methods are also only suitable for flat surfaces made of special materials, which is difficult to be widely applied.
On the other hand, in the field of fabric finishing, the traditional fluorine-containing acrylate finishing agent is mostly prepared by a solution polymerization method, wherein most of organic solvents are toxic, harmful and volatile, and although the effect is good, the finishing agent is unhealthy, not environment-friendly and has higher cost. Further, perfluorooctylsulfonyl derivatives (PFOS) having 8 carbon atoms and perfluorooctanoic acid compounds (PFOA) are often used as conventional fluorine-containing finishing agents, and they are considered to have excellent water-and-oil-repellent properties and good surface activity. However, PFOS is a perfluorocarbon compound which is chemically stable, environmentally durable, bioaccumulating and toxic, not easily degradable, and hazardous and potentially carcinogenic to organisms, and has been banned for use and import in european union countries.
