Polymer Brushes by Nitroxide‐Mediated Polymerization

Abstract

This review article describes the preparation of polymer brushes by nitroxide-mediated radical polymerization using either the 'grafting to' or the 'grafting from' approach. The use of TEMPO as a classical initiator is intensively described. More sophisticated nitroxides are also included in the discussion. Brush formation on flat surfaces such as wafers and also on particles is reported. Finally, some applications of polymer brushes are presented.

A review of immobilized antimicrobial agents and methods for testing

“…In the surface initiated or graft-from strategy, the AMA is essentially synthesized from surface bound initiators. Welldefined polymeric structures have been created through "living" or controlled polymerization techniques, 94 such as reversible addition fragmentation chain transfer polymerization, 95,96 nitroxide mediated polymerization, 97 and metal catalyzed living radical polymerizations such as atom transfer radical polymerization (ATRP). 98 In a similar but substantially more controlled manner, researchers can use solid phase synthesis methods to graft specific sequences of peptides and peptoids directly from a substrate.…”

Dynamic Microcrystal Assembly by Nitroxide Exchange Reactions

“…[8] Zeolites are crystalline aluminosilicates in which corner-sharing SiO 4 and AlO 4 tetrahedra create a negatively charged three-dimensional channel network. The negative charge of the framework is compensated by exchangeable cations present inside the channels.…”

Surface‐Initiated Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization of Styrene from Laponite Clay Surfaces

“…[2,3] The use of bifunctional ATRP (atom transfer radical polymerisation) and NMP (nitroxide mediated polymerisation) initiators or reversible addition fragmentation chain transfer (RAFT) agents offers a synthetic route to PCNs comprising welldefined homopolymer. [4][5][6][7][8][9] Some researchers in the field have subsequently proceeded to successfully make PCNs comprising block copolymers. [10] Surface-initiated controlled radical polymerisation (SI-CRP) has become a method of interest as it not only provides access to PCNs but also affords polymer brushes grafted to an inorganic surface.…”
