“…Therefore, effective surface modification approaches have been explored by using both chemical and physical treatments. 39,40 Singh and colleagues 41 have introduced alkyl bromide onto a polypropylene (PP) film surface through γ-ray irradiation in the presence of bromine vapor. Alkyl bromide-initiated ATRP of Nisopropylacrylamide on a polyolefin film has been found to produce thermosensitive hydrophilic polymeric brushes.…”

Direct surface modification of polymer fibers and films by surface-initiated polymerization has been investigated. The introduction of initiating sites on polymer materials and their successive polymerization produce surface-tethered polymer chains on the polymer surface. The surface-selective modification controls the surface properties, such as wetting, lubrication and antifouling, without sacrificing bulk performance. Among the various procedures for introduction of initiating groups and subsequent polymerization proposed to date, this focused review article highlights our studies on polymer brush grafting to electrospun polymer fibers and polymer films through surface-initiated polymerization. We review studies focusing on grafting polymer chains to five different types of solid polymers: poly(methyl methacrylate)-based copolymers, Br-containing polyolefins, poly(vinylidene fluoride-co-trifluoroethylene), poly(butylene terephthalate), and poly(ether-ether ketone).

“…SI-ATRP can be performed using, e.g. initiator-functionalized silanes [5], thiols [11,12], plasma-treated polymers [13], polyelectrolyte macroinitiators [ 14] and streptavidin-biotin conjugates [15]. Recently, we have proposed that ATRP of vinyl monomers can be initiated by electro-grafted brominated aryl species based on diazonium salts at the surface conductive materials such as iron [16], doped ultrananocrystalline diamond [17] and glassy carbon [18].…”

We report for the first time on grafting of poly(n-methyl methacrylate), (PMMA), and polystyrene (PS) brushes by ATRP from the surface of aligned multiwalled carbon nanotubes (MWCNT) which were electrochemically treated with brominated aryl groups based on diazonium salts. The polymer brushes formed amorphous coatings, as evidenced by high-resolution transmission electron microscopy, by comparison to the nanotube structure. X-ray photoelectron spectroscopy (XPS) analysis confirmed the presence of PS and PMMA by their characteristic C1s and valence band features. Well-aligned MWCNT network allowed us to sheath individual MWCNTs with polymer brushes while keeping the initial MWCNT alignment structure. This method opens up new avenues for the elaboration of polymer/NT hybrids.

“…2 The resulting polymer brushes allow the preparation, for example, of hybrid materials 3 or biocompatible surfaces. 4 ATRP can be surface-initiated using initiator-terminated silanes 1 and thiols, 5 photo-brominated surfaces 6 or macroinitiators. 7 Recently, we had shown that ATRP of vinyl monomers can be initiated by electro-grafted brominated aryl species based on diazonium salts.…”

Poly(methyl methacrylate), polystyrene, and polyglycidol brushes (PMMA, PS and PGL, respectively) were grown on glassy carbon (GC) plates that were modified by the electrochemical reduction of the diazonium salt BF 4 − , + N 2 -C 6 H 4 -CH(CH 3 )-Br. The grafted -C 6 H 4 -CH(CH 3 )-Br species were effective in surface-initiating atom transfer radical polymerization (SI-ATRP) of the vinyl monomers. The structure of the polymer brushes was characterized by XPS. Static contact angles of water drops on PS, PGL and PMMA brushes were 89.5 ± 2.0, 75.1 ± 7.0 and 83.5 ± 1.4°, respectively. The polymer brushes were further evaluated as adsorbents of human serum albumin (HSA). Protein adsorption decreased in the order PS > PGL ∼ PMMA. This highlights the resistance of PGL to protein adsorption.
