Introduction Highly branched polymers play an increasingly important role in interface and surface sciences, since their distinctive chemical and physical properties can be used advantageously as functional surfaces and as interfacial materials. Hyperbranched polymers grafted onto surfaces have also become a field of growing interest. Depending upon the substrates, it can be divided into 3D, 2D...

Protein patterning was carried out using a simple procedure based on photolithography wherein the protein was not subjected to UV irradiation and high temperatures, or contacted with denaturing solvents, and strongly acidic or basic solutions. Self-assembled monolayers of poly(ethylene glycol) (PEG) on silicon surfaces were exposed to oxygen plasma through a patterned photoresist. The etched re...

Single-walled carbon nanotubes (SWNT) were functionalized with polystyrene (PSt) by grafting to and grafting from methods. PSt-N3 with designed molecular weight and narrow molecular weight distribution was synthesized by atom transfer radical polymerization (ATRP) of styrene (St) followed by end group transformation and then added to SWNT. The grafting from functionalization was achieved by ATR...

A polymerizable ionic liquid, N,N-diethyl-N-(2-methacryloylethyl)-N-methylammonium bis(trifluoromethylsulfonyl)imide (DEMM-TFSI), was polymerized via copper-mediated atom transfer radical polymerization (ATRP). The polymerization proceeded in a living manner producing well-defined poly(DEMM-TFSI) of target molecular weight up to about 400 K (including a polycation and an counter anion). The acc...

In photo-atom transfer radical polymerization (ATRP), dispersity can be efficiently controlled by varying the deactivator concentration. this work, we provide mechanistic insight into dispersity-controlled photo-ATRP conducting detailed kinetics under a range of conditions. For lower polymers, conventional first-order kinetic profile was observed accompanied linear evolution number average mole...

Primary amine containing copolymer, poly(N,N-dimethylacrylamide-co-N-(3-aminopropyl)methacrylamide hydrochloride) (poly(DMA-co-APMA)), brushes were synthesized on Ti surface by surface-initiated atom transfer radical polymerization (SI-ATRP) in aqueous conditions. A series of poly(DMA-co-APMA) copolymer brushes on titanium (Ti) surface with different molecular weights, thicknesses, compositions...

We present the synthesis of dual-responsive (pH and temperature) magnetic core-shell nanoparticles utilizing the grafting-from approach. First, oleic acid stabilized superparamagnetic maghemite (γ-Fe(2)O(3)) nanoparticles (NPs), prepared by thermal decomposition of iron pentacarbonyl, were surface-functionalized with ATRP initiating sites bearing a dopamine anchor group via ligand exchange. Sub...

Since the emergence of surface modification techniques, including polydopamine (PDA) layers using a single deposition process that is based on the oxidative self-polymerization of dopamine (DA), the number of studies concerning the functionalization of material surfaces via PDA coating has increased. While PDA is simple to apply to cover onto various kinds of substrates, most of conventional PD...

Protein patterning was carried out using a simple procedure based on photolithography wherein the protein was not subjected to UV irradiation and high temperatures or contacted with denaturing solvents or strongly acidic or basic solutions. Self-assembled monolayers of poly(ethylene glycol) (PEG) on silicon surfaces were exposed to oxygen plasma through a patterned photoresist. The etched regio...

Cellulose-graft-poly(methylmethacrylate) (cellulose-g-PMMA) copolymers were prepared by homogeneous atom transfer radical polymerization (ATRP) under mild conditions, in an attempt to develop an efficient way to modify the surface of cellulose. A cellulose macro-initiator was successfully synthesized by direct homogeneous acylation of cellulose with 2-bromopropionyl bromide in a room temperatur...
