Abstract

Electrospun fine fibers were surface-modified by surface-initiated atom transfer radical polymerization (SI-ATRP) to reform their surface character without sacrificing their bulk properties. Electrospun fibers of two types of polymers, poly(methyl methacrylate)-based copolymers and semi-crystalline poly(butylene terephthalate), that have ATRP initiating units attached to them were modified by poly(sulfobetaine) brushes or fluorinated polymer brushes. The fluorinated polymer brushes make the electrospun fiber mat super-hydrophobic, whereas the poly(sulfobetaine) brushes make the electrospun fiber super-hydrophilic. These mats can be used for water/oil separation and exhibit non-fouling properties. The semi-crystalline polyester fibers keep these properties even at elevated temperatures.
