Surface Functionalization of Electrospun Poly(butylene terephthalate) Fibers by Surface-Initiated Radical Polymerization

Abstract

A facile surface modification procedure for electrospun poly(butylene terephthalate) (PBT) fibers by surface‐initiated atom transfer radical polymerization (SI‐ATRP) is reported. Initiators are introduced through aminolysis and chemical vapor adsorption. SI‐ATRP is subsequently carried out to prepare a polymer‐grafted layer at the PBT fiber surface without altering the fiber geometry. After modification with a zwitterionic poly(sulfobetaine), poly(3‐(N‐2‐methacryloyloxyethyl‐N,N‐dimethyl) ammonatopropanesulfonate), the surface is superhydrophilic. The surface properties are thermally stable due to the high melting temperature of the PBT crystallites and are maintained for a prolonged period.

Direct polymer brush grafting to polymer fibers and films by surface-initiated polymerization

“…32 In that work, we prepared electrospun PBT fibers from a 8.0 wt% hexafluoro-2-propanol solution of PBT (Figure 4a). The APTES was introduced by soaking the as-spun PBT fiber mat in an APTES toluene solution through aminolysis.…”

“…25 We have reported surface-initiated ATRP (SI-ATRP) from polymeric solids, such as electrospun fibers and films. [26][27][28][29][30][31][32][33] Various polymers with different physicochemical properties have been introduced on the polymer surfaces to modify the surface properties without sacrificing the bulk performance and morphology of the polymeric solids.…”

“…We describe polymer brush grafting on five types of polymer substrates: poly(methyl methacrylate) (PMMA)-based copolymers, 26,27 Br-containing polyolefins, 28,29 poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-co-TrFE)) copolymers, 30,31 poly (butylene terephthalate) (PBT) 32 and PEEK 33 (Scheme 1).…”

Dual-Functional Grafted Electrospun Polymer Microfiber Scaffold Hosted Palladium Nanoparticles for Catalyzing Redox Reactions

“…Noble metal and ceramic nanoparticles (NPs) have been successfully incorporated on different polymer matrices for making easily retrievable and recyclable heterogeneous catalysts without affecting catalytic activity of the NPs . There are two possibilities to anchor NPs in electrospun polymer fibers; one during electrospinning, and second postprocessing of the fibers . The postprocessing of electrospun polymer fibers has advantage that the NPs can be positioned on the surface to provide higher accessibility.…”
