Assembly of an unbalanced charged polyampholyte onto Nafion to produce high-performance composite membranes
A novel SPES-NH2–GA-Nafions composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH2) and glutaraldehyde (GA) with controllable free sulfonic acid content.

Improvement of the thermal and thermo-oxidative stability of high-density polyethylene by free radical trapping of rare earth compound
A kind of rare earth compound, ytterbium trifluoromethanesulfonate (Yb(OTf)3), was introduced into high-density polyethylene (HDPE) by melt compounding to investigate the effect of Yb(OTf)3 on the thermal and thermo-oxidative stability of HDPE. The results of thermogravimetric (TG) and differential scanning calorimetry (DSC) showed that the addition of Yb(OTf)3 made the thermal degradation tempera...

Versatile controlled ion release for synthesis of recoverable hybrid hydrogels with high stretchability and notch-insensitivity
A versatile ion release mediated by GDL is demonstrated to achieve a controlled homogeneous crosslinking of alginate chains, which is critical for the synthesis of highly stretchable and notch-insensitive hybrid hydrogels with controlled properties.

Well-defined high refractive index poly(monothiocarbonate) with tunable Abbe''s numbers and glass-transition temperatures via terpolymerization
The synthesis of thermoplastics with high refractive index (n) and high Abbe’s number (Vd) is rarely reported. This work describes well-controlled synthesis of a soluble poly(monothiocarbonate) with high n and Vd values by using carbonyl sulfide (COS) as sulfur resource. The alternating COS/cyclohexene oxide (CHO)/propylene oxide (PO) terpolymerization was well performed by using...

Synthesis of High Molecular Weight Cyclic Poly(ε-caprolactone)s of Variable Ring Size Based on a Light-Induced Ring-Closure Approach
High molecular weight cyclic poly(ε-caprolactone)s (cPCLs) with variable ring size are synthesized via light-induced ring closure of α,ω-anthracene-terminated PCL (An-PCL-An). The ring size of cPCL is tunable simply by adjusting the polymer concentration from 10 to 100 mg mL?1 in THF. The cycloaddition via the bimolecular cyclization of An-PC-An is well characterized by a variety of ...

Driving of Droplet on Nano-Gradient Microhump Surface in Low-Temperature and High-Humidity Environment
Directional driving of a droplet can be achieved on a gradient-exhibiting,nanostructured microhump (GNMH) surface at low temperature and high humidity. The GNMH surface is fabricated using a commercial carbon fiber plate with an array of microscale hump structures; nanotechniques are used to form varying nanostructures on the microhump array, producing the micro- and nanostru...

[2015][Macromolecules, 2015, 48 (12), 3941–3948]Optimization of Broad-Response and High-Detectivity Polymer Photodetectors by Bandgap Engineering of Weak Donor–Strong Acceptor Polymers
A series of weak donor–strong acceptor polymers containing two different electron-deficient units (diketopyrrolopyrrole and thienoisoindigo) are synthesized and used in broad-response and high-detectivity polymer photodetectors. By adjusting the composition ratio of the two acceptors, the absorption spectra, energy levels, molecular stacking, and film morphology are affected, which in turn infl...
