Controlled/Living Free Radical Polymerization of PS-b-P4-VP Brush Initiated from the Alkoxyamine-Functionalized Silicon Surface

摘要

Diblock copolymer brushes of polystyrene and poly (4-vinylpyridine) (PS-b-P4-VP) were synthesized by sequential monomers addition to a monolayer of 3-methacryloxypropyltrimeth-oxysilane. The diblock brushes were characterized by X-ray Photoelectron Spectroscopy (XPS) and Atomic Force Microscope (AFM). The results suggested that the 3-methacryloxypropyltrimeth-oxysilane initiator layer grafted on the silicon surface and the PS-b-P4-VP chains were covalently anchored onto the Si/SiO₂/3-MPS surface.View full textDownload full textKeywords3-methacryloxypropyltrimeth-oxysilane, Grafting, Nitroxide-mediate, Polymer brushes, Radical polymerizationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/03602559.2012.704112
