“…These intrinsic amphiphilic brushes are potentially useful in many applications, including surface activation, data storage, nanolithography, chemical sensing, cellular engineering, and micrometer-scale patterning. [11][12][13][14][15] Atom transfer radical polymerization (ATRP) is quite often used as a controlled means to synthesize polymers from a wide range of monomers. [16] Numerous relevant research works were carried out in the application of modification on silicon surface via surface-initiated ATRP.…”

“…[16] Numerous relevant research works were carried out in the application of modification on silicon surface via surface-initiated ATRP. [11][12][13][14][15][16][17][18] In this paper the simple approach of UV-induced coupling of 4-vinyl benzyl chloride (VBC) with the Si-H surface was adopted to produce a stable, Si-C bonded, monolayer of ATRP initiators (the Si-VBC suface). [19] The hydrophilic and hydrophobic polymer segments were obtained respectively from poly(ethylene glycol) methacrylate (PEGMA) macromonomer and 2,2,3,3,4,4,4heptafluorobutyl acrylate (HFBA), and the structure of amphiphilic diblock copolymer brush was Si-VBC-g-P(HEMA)-g-P(HFBA)-b-P(PEGMA).…”

Well-defined amphiphilic graft polymer brushes containing fluoropolymer segments have been successfully prepared by (i) UV-induced coupling of 4-vinylbenzyl chloride (VBC) with the hydrogen-termined Si(100) (Si-VBC surface), (ii) surface-initiated atom transfer radical polymerization (ATRP) of 2-hydroxyethl methacrylate (HEMA) to produce the Si–VBC–g–P(HEMA) surface as the backbone of macroinitiator for further ATRPs, (iii) coupling of 2-bromoisobutyrl bromide with the HEMA polymer(P(HEMA)) by the esterification to produce the macroinitiators for the subsequent ATRP(Si–VBC–g–P(HEMA)-R3Br), (iv) surface-initiated ATRP of 2,2,3,3,4,4,4-heptafluorobutyl acrylate (HFBA) to produce the Si–VBC–g–P(HEMA)–g–P(HFBA) surface, and (v) the active P(HFBA) chain ends being used as the initiator for the subsequent ATRP of poly(ethylene glycol) monomethacrylate (PEGMA) to produce the amphiphilic Si–VBC–g–P(HEMA)–g–P(HFBA)–b–P(PEGMA) brush surface. The chemical composition and functionality of the silicon surface were characterised by X-ray photoelectron spectroscopy (XPS), atomic force microscope (AFM) and ellipsometry.
