Dense, Highly Hydrated Polymer Brushes via Modified Atom-Transfer-Radical-Polymerization: Structure, Surface Interactions, and Frictional Dissipation

30-Dec-2014 | Odeya Tairy; Nir Kampf; Michael J. Driver; Steven P. Armes; Jacob Klein, Macromolecules, 2014

The conditions for atom transfer radical polymerization (ATRP) of poly[2-(methacryloyloxy)ethyl phosphorylcholine] (pMPC) chains are modified to enable much more efficient growth of these poly zwitterionic chains from macroinitiator-coated mica substrates using the “grafting from” technique. In ...


Evidence for Catalyst Association in the Catalyst Transfer Polymerization of Thieno[3,2-b]thiophene

12-Dec-2014 | Pieter Willot; Guy Koeckelberghs, Macromolecules, 2014

The performance of catalyst transfer polymerization (CTP) reactions which depend on catalyst association was studied on 3,6-dioctylthiothieno[3,2-b]thiophene (TT)-monomers. This monomer was selected because a strong association of the catalyst is expected, since the aromaticity of thienothiophene ...


Hydration and Ordering of Lamellar Block Copolymer Films under Controlled Water Vapor

12-Dec-2014 | Yohei Kamata; Andrew J. Parnell; Philipp Gutfreund; Maximilian W. A. Skoda; Andrew J. C. Dennison; Robert Barker; Sh ..., Macromolecules, 2014

Amphiphilic block copolymers within a range of volume fraction spontaneously form vesicles in aqueous solution, where a water core is enclosed by a polymer bilayer. Thin-film rehydration is a method used to produce vesicles routinely; a thin film is immersed in water, the film swells, and ...


Quadruple-Stimuli-Sensitive Polymeric Nanocarriers for Controlled Release under Combined Stimulation

12-Dec-2014 | Ziquan Cao; Hao Wu; Jie Dong; Guojie Wang, Macromolecules, 2014

Here we report a novel quadruple-stimuli-responsive block copolymer nanocarrier sensitive to pH, temperature, light, and reducing agent. The well-defined amphiphilic diblock copolymer poly(2-nitrobenzyl methacrylate)-SS-poly(dimethylaminoethyl methacrylate) (PNBM-SS-PDMAEMA) was synthesized via ...


Temperature Driven Macromolecule Separation by Nanoconfinement

10-Dec-2014 | Ilaria De Santo; Filippo Causa; Paolo A. Netti, Macromolecules, 2014

We focused on the influence of temperature variations on macromolecule partitioning between unconfined and nanoconfined areas in nanoslits using single molecule measurements. We evaluated the number of fluorescent poly(ethylene glycol) (PEG) molecules confined in glass nanoslits in several ...


Synthesis of Anthracene-Based Donor–Acceptor Copolymers with a Thermally Removable Group for Polymer Solar Cells

02-Dec-2014 | Chunchen Liu; Wenzhan Xu; Xing Guan; Hin-Lap Yip; Xiong Gong; Fei Huang; Yong Cao, Macromolecules, 2014

A highly soluble anthracene cyclic adduct with a thermally cleavable substituent was synthesized, and it was used as a donor unit in a series of donor–acceptor type conjugated copolymers with improved processability. The removable group was eliminated under elevated temperature through retro ...


Analytical Solution of Free Radical Polymerization: Applications-Implementing Nonisothermal Effect

02-Dec-2014 | Dhiraj K. Garg; Christophe A. Serra; Yannick Hoarau; Dambarudhar Parida; M. Bouquey; R. Muller, Macromolecules, 2014

Analytical solution (AS), as derived in our previous works for isothermal free radical polymerization (FRP), has been extended to nonisothermal conditions in this work. Only one differential equation, i.e., the energy balance equation, was required to calculate temperature profile by stiff solver ...


Unprecedented Lower Critical Solution Temperature Behavior of Polyimides in Organic Media

01-Dec-2014 | Sun Dal Kim; Sang Youl Kim; Im Sik Chung, Macromolecules, 2014

Macromolecules DOI: 10.1021/ma501921z


Mechanically Induced Gelation of a Kinetically Trapped Supramolecular Polymer

01-Dec-2014 | Abraham J. P. Teunissen; Marko M. L. Nieuwenhuizen; Fransico Rodríguez-Llansola; Anja R. A. Palmans; E. W. Meijer, Macromolecules, 2014

The stimuli-induced gelation of a urethane-functionalized ditopic ureidopyrimidinone (UPy) compound is presented, and the mechanism by which the gelation proceeds is proposed. In a 40–120 mM solution in chloroform, the compound can exist in two different aggregated states, namely a low viscous ...


Aromatic Copolymers Containing Ammonium-Functionalized Oligophenylene Moieties as Highly Anion Conductive Membranes

26-Nov-2014 | Naoki Yokota; Manai Shimada; Hideaki Ono; Ryo Akiyama; Eriko Nishino; Koichiro Asazawa; Junpei Miyake; Masahiro Wata ..., Macromolecules, 2014

The synthesis and properties of anion conductive aromatic copolymers containing oligophenylene moieties as a scaffold for quaternized ammonium groups are reported. Our new hydrophilic components consist of a chemically robust oligophenylene main chain modified with a high density of ionic groups. ...
