[Chem. Commun] Reversible morphology transitions of supramolecular polymer self-assemblies for switch-controlled drug release
A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
In this st...

Equal Low-Order Finite Element Simulation of the Planar Contraction Flow for Branched Polymer Melts
The rheological characteristics of branched polymer melts
is described by the modified XPP model, which is discretized by
inconsistent streamline-upwind method. A finite increment calculus
procedure is introduced to reformulate the mass equation and to
overcome oscillations of the pressure field. Moreover, the governing
equations are discretized and solved by the iterative fractional step
algorith...

Catechol-functionalized microporous organic polymer as supported media for Pd nanoparticles and its high catalytic activity
We report a new hydroxyl functionalized microporous organic polymer (MOPOH) based on the polymerization of catechol with terephthalaldehyde using phenolic resin-inspired chemistry. This catechol-decorated material, with surface area of 874 m2 g?1 and micro, mesopores, facilitates the immobilization and dispersion of Pd nanoparticles (NPs) on the polymer matrix. The surface area of t...

[Polym. Chem.] Wafer-scale Synthesis of Defined Polymer Brushes under Ambient Conditions
A method is presented that allows for the first time the preparation of highly defined polymer brush coatings on the wafer-scale under ambient conditions (room temperature, exposure to air) from a broad variety of monomers. The discovered high oxygen-tolerance of the surface-initiated Cu(0)-mediated controlled radical polymerization (SI-CuCRP) yields entire wafers homogeneously covered by a polyme...

Novel sulfonated polyimide/zwitterionic polymer-functionalized graphene oxide hybrid membranes for vanadium redox flow battery
Hybrid membranes (SPI/ZGO) composed of sulfonated polyimide (SPI) and zwitterionic polymer-functionalized graphene oxide (ZGO) are fabricated via a solution-casting method for vanadium redox flow battery (VRB). Successful preparation of ZGO fillers and SPI/ZGO hybrid membranes are demonstrated by FT-IR, XPS and SEM, indicating that ZGO fillers is homogeneously dispersed into SPI matrix. Through co...

Study of pH/ temperature dual stimuli-responsive nanogels with interpenetrating polymer network structure
Nanogels with interpenetrating polymer network (IPN) structure based on poly(N-isopropylacrylamide) (PNIPAM) and
poly(acrylic acid) (PAA) were synthesized by in situ polymerization of acrylic acid and N, N-methylenebisacrylamide within the PNIPAM nanogels. Their IPN structure was confirmed using transmission electron microscopy after staining by uranyl acetate. The temperature- or pH-dependent hy...
