Electrospun nanofiber membranes surface functionalized with 3D nanolayers through ATRP provide adsorption capacities over 50-times higher than current commercial membrane adsorption systems and over 12-times higher than packed bed resins; additionally, the adsorption kinetics remain 10-times faster than packed bed resins and have over 15-times higher permeance.

Poly(p-phenylenevinylene)s (PPVs) with single reactive end groups have been prepared with high molecular weights, narrow polydispersities (ĐM) and excellent end functionality (f). PPVs functionalised with α-bromoester end groups are effective macroinitiators in the atom transfer radical polymerisation (ATRP) of methyl methacrylate (MMA).

In this communication, we report on a new route to the functionalization of ATRP polymers exploiting their halide end-groups, which were converted successfully into reactive disulfide end-groups, using sodium methanethiosulfonate. The resultant disulfide-terminated polymers could then be reacted with different functional thiols to yield functional polymers exploiting either thiol/disulfide exch...

An ATRA based strategy to synthesize vinyl copolymers with monomer-level sequence control is proposed. In each cycle, one allyl alcohol is added to the ATRP chain end, and then the hydroxymethyl residue is oxidized to carboxylic acid and a side group is introduced via esterification, making the new chain end active for the next cycle.

The combination of superior optoelectronic properties and enhanced solubility for regioregular poly(3-hexylthiophene) (rr-P3HT) has enabled materials based on P3HT to be widely used for organic field-effect transistors, chemical sensors, and photovoltaic solar cells. Significantly, the optoelectronic performance of rr-P3HT thin film has been shown to depend on molecular weight, processing condi...

An acid labile branched PDMAEMA/acetal copolymer with amino group was synthesized by the DE-ATRP and followed by Michael addition. The degradation of the polymer was strongly pH-dependent. High nucleic acid transfection efficiency with low cytotoxicity was observed compared to its non-degradable copolymer counterpart.

An environmentally friendly and controllable P(VDF-co-CTFE) hydrogenation route involving the transition-metal complex mediated radical chain transfer reaction is successfully developed to synthesize P(VDF-co-CTFE-co-TrFE). The typical transition metal catalysts of ATRP reaction could be applied in this process.

An ABA type amphiphilic triblock copolymer was synthesized via ATRP and sulfonation. New self-assembled morphologies such as toroidal vesicles, giant tubular vesicles, and perforated spherical vesicles were observed from triblock copolymer-polyaniline complexes in water. The mechanism of morphology transformation at different compositions was discussed.

The scale-up of Atom Transfer Radical Polymerization (ATRP) from 15 mL to L (scale-up factor 1000) by galvanostatic simplified electrochemically mediated ATRP (seATRP) is disclosed. An electrochemical O2 scavenging cycle was embedded in the equilibrium allow self-degassing mixture and avoid impractical deoxygenation procedures. Low volume seATRP acrylamide water optimized studying various react...

Hybrid Fe(3)O(4)@SiO(2)@PEG-Maltose MNPs were synthesized by SI-ATRP of branched PEG brushes on the surface and subsequent functionalization with hydrophilic maltose group, and the multifunctional materials were utilized for selective enrichment of N-linked glycopeptides from biological samples with high specifity, high sensitivity, and large binding capacity.
