Polymer chemistry

Polymer chemistry is the study of the synthesis, characterization and properties of polymer molecules or macromolecules, which are large molecules composed of repeating chemical subunits known as monomers.

    Three-dimensional (3D) priming, which encapsulates human adipose derived stem cells into hydrogel systems, greatly reduces the amount of time required to induce an efficient retroviral transduction compared with the conventional two-dimensional (2D) method. This facilitating effect is closely related to the acceleration of cell cycle regulation (G1 arrest and G1/S transition) by 3D priming.

    Super engineering plastics that utilise bio-derived cyclic monomers rarely offer the same thermal/mechanical properties, scalability and recyclability as petrochemical derived plastics. Here the authors use a phase transfer catalyst to synthesise a transparent, recyclable and tough isosorbide-based polymer with a high molecular weight.

    The formation of polymer nanoparticles with a uniform size and shape, beyond spheres, is an unresolved problem. Here the authors show a living aqueous catalytic polymerization forming single crystal particles grown by a single active site and composed of a single ultra high molecular weight polyethylene chain.

    Surface-grafting polymer brush (SPB) technique can be used to change the inherent physical/chemical properties of materials surface. Practical applications are paid more attention since SPB technique enables to decorate materials with diverse functions. This paper reviews the current grafting strategies to generate polymer brush layer on surface of solid materials with diverse geometric structures/sizes, and then systematically summarizes the recent research advances on application of polymer brushes-modified materials. Correspondingly, some key challenges of SPB technique with considering its real application in future are discussed. The aim to draft this paper is to tell the readers how to engineer functional materials by SPB technique.

    DNA is a biological building block which has drawn much attention as a structural material for a range of applications. Here, the authors report that DNA structures can be templated using shear-induced flow and microposts for controllable DNA patterning.

    We demonstrated the synthesis of fluorescent network polymers through Knoevenagel polycondensation of an (tris(p-formylphenyl)amine) with a phenylenediacetonitrile. The structure based on the electron-donor triphenylamine and electron-acceptor cyano-substituted phenylene-vinylene showed a highly efficient solid-state fluorescence. The model molecule showed a well-defined solvatofluorochromism. Surprisingly, the network polymer linked with para-phenylene-vinylene was only responsive to the solvents with a low dielectric constant and nitrobenzene. The network polymer linked with meta-phenylene-vinylene was responsive to the aromatic solvents only. The characteristic chemoselectivity was observed by the geometric effect of the network structure.

    The longstanding ‘polyelectrolyte theory of the gene’ proposes that a multiply charged backbone is the universal signature of all genetic polymer systems that support life. Now, the first tenable challenge to this theory has been mounted, through the successful engineering of enzymes which can synthesize and reverse-transcribe from an artificial, uncharged nucleic acid analogue.

    Diluting a base element with small amounts of another has served as the basis for developing alloys for thousands of years since the advent of bronze. Today, a fundamentally new idea where alloys have no single dominant element is giving new traction to materials discovery.

    The mechanics of many materials can be modelled by a network of balls connected by springs. A bottom-up approach based on differential geometry now captures changes in mechanics upon network growth or merger, going beyond the linear deformation regime.
