Zwitterionic polymer-grafted superhydrophilic and superoleophobic silk fabrics for anti-oil applications

A highly anti‐oil fabric membrane is synthesized by surface grafting of zwitterionic poly(sulfobetaine methacrylate) (PSBMA) onto the fabric surface. The fabric membrane is first enzymatically modified to create more reactive amine groups on the surface. A surface‐initiated atom transfer radical pol...

Description
Summary:A highly anti‐oil fabric membrane is synthesized by surface grafting of zwitterionic poly(sulfobetaine methacrylate) (PSBMA) onto the fabric surface. The fabric membrane is first enzymatically modified to create more reactive amine groups on the surface. A surface‐initiated atom transfer radical polymerization (SI‐ATRP) reaction is then performed to modify the fabric membrane surface with a dense PSBMA brush layer. Surface characterization indicates that the brush‐grafted fabric membrane exhibits increased surface roughness and improved superhydrophilicity. The PSBMA‐modified silk fabrics show a very large contact angle for oil droplets in water, and have excellent oil resistance in air and in water–oil mixtures.
