Preparation of Durable Superhydrophobic Cotton Fabric for Selfcleaning and Oil-water Separation

다국어 초록 (Multilingual Abstract)

Improving the surface roughness and reducing the surface energy are the main strategies for constructing cottonfabrics with superhydrophobic surface. However, the complex finishing process and poor durability still impede theproduction and application of superhydrophobic cotton fabrics. Therefore, it is critical to produce superhydrophobic fabricswith excellent durability via a noncomplicated method. In this work, monomers of methyl methacrylate (MMA) andtrifluoroethyl methacrylate (TFMA) were polymerized via free radical polymerization to produce a fluoropolymer. Then, thefabric was coated with the fluoropolymer to construct a superhydrophobic surface via the pad-dry-cure technology. TheTFMA unit in the fluoropolymer had lower surface energy than the MMA unit. Under the high-temperature curing condition,the MMA unit in the fluoropolymer was grafted onto the cotton fabric via transesterification, and the TFMA was exposed onthe fabric surface. The finished fabric showed durable superhydrophobic properties, outstanding oil-water separationproperties, and excellent self-cleaning properties. Given the results, the finished fabric has great potential application inclothing and industrial fields.
