Abstract In this study, we show the controlled self-oscillation behavior (i.e., normalized amplitude, swelling rate, and deswelling rate) of self-oscillating gels by introducing grafted chains. The chain was introduced to base gel network “grafting from” method atom-transfer radical polymerization (ATRP). We demonstrated that properties chain, including monomer composition length can lead notab...

Polymers with tailored architectures and degradability were prepared through thiocarbonyl addition ring-opening (TARO) atom-transfer radical polymerization (ATRP) using dibenzo[c,e]oxepin-5(7H)-thione (DOT), Cu(I)Br, tris[2-(dimethylamino)ethyl]amine (Me6TREN) as the thionolactone, catalyst, ligand, respectively, in combination a selection of acrylic comonomers. Although copolymers selectively ...

Polymer brushes produced by controlled surface-initiated polymerization provide a route to surfaces coated with well-defined thin polymer films that are covalently bound to the substrate. All of the major controlled polymerization techniques have been applied to the synthesis of polymer brushes and examples of each are presented here. Many examples of brush synthesis in the literature have used...

A proof-of-concept study demonstrated the feasibility of a novel gel-pad microarray on porous silicon chips, by initiation of an atom transfer radical propagation (ATRP) polymerisation of (polyethylene glycol) methacrylate (PEGMA) with surface Si-H species, stepwise chemical conversions of the gel membrane to an NTA-Ni2+/histidine-tagged protein system, and matrix-assisted laser desorption/ioni...

A new and general design strategy is presented for amphiphilic block copolymers whose micellar aggregates can be dissociated by light. A diblock copolymer composed of hydrophilic poly(ethylene oxide) (PEO) and a hydrophobic polymethacrylate bearing pyrene pendant groups (PPy) was synthesized using ATRP. Upon UV light irradiation of polymer micellar solutions, the photosolvolysis of pyrene moiet...

The surface of magnetite nanoparticle (MNP) was modified with poly(acrylic acid)(PAA)-poly(ethylene glycol) methyl methacrylate (PEGMA) (co)polymer to obtain water dispersible MNP pH sensitive surfaces via atom transfer radical polymerization (ATRP) tert-butyl acrylate (t-BA), followed by the t-BA group deprotection. Molar compositions were systematically varied, namely 100:0, 75:25, 50:50 and ...
