Facile synthesis of recyclable Zn(II)- metallosupramolecular polymers and the visual detection of tensile strength and glass transition temperature
We have successfully constructed a novel type of recyclable crosslinked Zn(II) metallosupramolecular coordination polymer, which possessed outstanding thermal stability and mechanical properties. More importantly, the tensile strength (RM) and glass transition temperature (Tg) of the resulting crosslinked films could be visually detected by taking advantage of the transparency decreasing effect ...

Metal-coordination crosslinked N-polyindoles as recyclable high-performance thermosets and nondestructive detection for their tensile strength and glass transition temperature
Metal coordination crosslinking between stiff N-polyindole chains was constructed, and the crosslinked films exhibited high tensile strength, high heat resistance and excellent polar solvent resistance. The noncovalent crosslinking can be further removed via external pyrophosphate, which endows the crosslinked polymer with a recyclable behavior. The tensile strength and glass transition temperat...

[Nature Chemistry] Photoswitching of Glass Transition Temperatures of Azobenzene-containing Polymers Induces Reversible Solid-to-liquid Ttransitions
The development of polymers with switchable glass transition temperatures (Tg) can address scientific challenges such as the healing of cracks in high-Tg polymers and the processing of hard polymers at room temperature without using plasticizing solvents. Here, we demonstrate that light can switch the Tg of azobenzene-containing polymers (azopolymers) and induce reversible solid-to-liquid transi...

017. Multiscale modeling of glass transition in polymeric films: Application to stereoregular poly(methyl methacrylate)s
The multiscale modeling scheme has been extended to derive the coarse-grained potentials for simulating glass transition temperatures (Tg) of the bulks and the freely-standing films of two stereoregular poly (methyl methacrylate) (PMMA) configurations. The extensive molecular dynamics simulations reasonably reproduce the volumetric properties. Furthermore, the “dynamical Tg” sensibly exhibits ...

Enhanced cycling stability of Li–O2 batteries by using a polyurethane/SiO2/glass fiber nanocomposite separator
A considerable improvement in the cycle performance of aprotic Li–O2 batteries was achieved by using a polyurethane/SiO2 gel nanoparticles/glass fiber (PU/SiO2/GF) nanocomposite separator, where a persistent capability of 1000 mA h g1 was maintained for at least 300 charge/discharge cycles in a DMSO electrolyte with 1 M LiClO4 and 0.05 M LiI. In comparison, the cell with a conventional GF sepa...

158. Supertoughened Polylactide Binary Blend with High Heat Deflection Temperature Achieved by Thermal Annealing above the Glass Transition Temperature
Through thermal annealing above the glass transition temperature, a supertoughened binary blend with the highest notched Izod impact strength of 98 KJ/m2 was achieved, which was about 52 times of that of neat polylactide (PLA; 1.9 KJ/m2). The binary blend was composed of biocompatible and biodegradable PLA and ethylene?acrylic ester?glycidyl methacrylate terpolymer (EGMA) elastomer at the compos...

Magnetic impurity doping induced spin-glass state and short-range zigzag order in the honeycomb iridate Na2IrO3
Based on the modied Heisenberg-Kitaev model, the eects of magnetic substitution on the magnetic properties of the honeycomb-lattice iridate Na2IrO3 are studied using Monte Carlo simulations. It is observed that the long-range zigzag state of the original system is rather fragile and can be replaced by a spin-glass state even for small substitution, well consistent with the experimental observation...

4.【J. Appl. Polym. Sci.】 Pressure-Dependent Glass-Transition Temperatures of poly(methyl methacrylate) /poly(styrene-co-acrylonitrile) Blends
The pressure-dependent glass-transition temperatures (Tgs) of poly(methyl methacrylate) (PMMA)/poly(styrene-co-acrylonitrile) (SAN) blends were determined by pressure–volume–temperature (PVT) dilatometry via an isobaric cooling procedure. The Gordon–Taylor and Fox equations were used to evaluate the relationships between the Tgs and compositions of the PMMA/SAN system at different pressures. ...

THE GLASS FORMATION OF A REPULSIVE SYSTEM WITH ALSO A SHORT RANGE ATTRACTIVE POTENTIAL: A RE-INTERPRETATION OF THE FREE VOLUME THEORY
In this feature article, we first make some simple reviews about the most popular theories for glass transition: 1) Free volume theory, 2) Entropy theory, 3) G€otze’s Mode coupling theory, and 4) Caging and Jamming theory.We address the issue of existing studies of glass transformations. Then, we review some special colloidal/polymer model systems which can give a repulsive potential together w...
