Enhancement of Proton Conduction at Low Humidity by Incorporating Imidazole Microcapsules into Polymer Electrolyte Membranes
Design and fabrication of hierarchically structured membranes with high
proton conductivity is crucial to many energy-relevant applications including
proton exchange membrane fuel cell (PEMFC). Here, a series of imidazole
microcapsules (IMCs) with tunable imidazole group loading, shell thickness,
and lumen size are synthesized and incorporated into a sulfonated poly(ether
ether ketone) (SPEEK) mat...

Enhancing the water uptake and retention of membrane by embedding polymer hollow spheres as the water reservoirs
Water retention is a pervasive issue in agriculture and industry. Inspired
by the water-storage mechanisms in plant cells, three kinds of polymeric
microcapsules (PMCs) with carboxylic acid, sulfonic acid, and pyridyl groups
are prepared using distillation–precipitation polymerization. The size of the
lumen of the PMCs may govern the static water uptake by holding water
molecules in a free-water ...

Low Cationic Proportion Ampholytic Polymer: Synthesis, Solution Properties and Interaction with Anionic Surfactant.
Novel ampholytic terpolymer of N-vinylformamide (NVF), vinylamine (VAm) and sodium acrylate (NA) with low cationic proportion was obtained by hydrolyzing copolymer of NVF and NA (PNVFNA). Solution properties of the polymer were investigated by methods of turbidity and viscosity experiment. The effect of sodium dodecyl sulfate (SDS) on solution viscosity was also investigated. The results showed th...

Photoenhanced gene transfection by a star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms
A star-shaped polymer (PP-PLLD) consisting of a porphyrin (PP) core and poly(L-lysine) dendron arms (PLLD) is synthesized by the click reaction, and its ability to deliver pEGFP is investigated in this paper. It is found that PP-PLLD has a good buffer capacity and can form compact complexes with pEGFP. In vitro assay indicates that PP-PLLD shows photoenhanced gene transfection efficiency. PP-PLLD ...

Robust microsieves with excellent solvent resistance: cross-linkage of perforated polymer films with honeycomb structure
Polymeric microsieves with uniform and tunable pores were fabricated with the breath-figure method and sequent vulcanization procedure using commercially available block copolymer polystyrene-b-polyisoprene-b-polystyrene. Uniform pore size and small film thickness endow the microsieves with high size selectivity and low operation pressure, while the cross-linked chemical structure gives them goo...

[Chem Commun] A Microcontacting Printing Induced Supramolecular Self-Assembled Photo Active Surface for Patterning Polymer Brushes
A facile and robust strategy for creating micropatterned polymer brushes via the combination of micro-contact printing (μCP) induced supramolecular self-assembled photo active surface with subsequent self-initiated photografting and photopolymerization (SIPGP) is reported. The results contribute to polymeric functionalization on a wide range of hydroxylated surface or graphene based materials

Hemiphasmidic Side-Chain Liquid Crystalline Polymer: From Smectic C Phase to Columnar Phase with a Bundle of Chains as Its Building Block
We synthesized a new hemiphasmidic side-chain liquid crystalline polymer (P-n, n is the number of carbons in alky tail of the side chain, n = 4?12) using free radical polymerization. The side chain of P-n has a biphenyl in the middle, linked to the polystyrene backbone and to the terminal phenyl group with three alkyl tails via only methyleneoxy units. Upon increasing n,...
