160. Making a rapid completion of crystallization for bisphenol A polycarbonate by a double-layer film method
Bisphenol A polycarbonate (PC) is difficult to crystallize. In this study, it was found that PC could rapidly accomplish melt crystallization only within 8 min by laying poly(ethylene glycol) (PEG) film on it. Polarized optical microscope (POM) was applied to trace the growth of spherulites of PC in PEG/PC double-layer films during isothermal crystallization in a wide range of temperatures, whic...

[Macromol. Rapid Com.]Ratiometric Fluorescent pH Probes Based on Glycopolymers
Effectively detecting pH changes plays a critical role in exploring cellular functions and determining physiological and pathological processes. A novel ratiometric pH probe based on a glycopolymer, armored with properties of serum-stability, tumor-targeting, and pH monitoring, is designed. Random copolymers of 2-(methacrylamido) glucopyranose and fluorescein O-methacrylate are first synthesized...

【Macromol. Rapid Commun】Mechanical Robust and Self-Healable Supramolecular Hydrogel
Development of self-healing polymers with spontaneous self-healing capability and good mechanical performance is highly desired and remains a great challenge. Here, mechanical robust and self-healable supramolecular hydrogels have been fabricated by using poly(2-dimethylaminoethyl methacrylate) brushes modified silicananoparticles (SiO2@PDMAEMA) as multifunctional macrocrosslinker...

[Macromol. Rapid Commun.] Polymer Brushes on Planar TiO2 Substrates
A facile and universal method is presented for the preparation of polymer brushes on amorphous TiO2 film. Homogeneous and stable poly(methyl methacrylate), polystyrene, poly(4-vinylpyridine), and poly(N-vinyl imidazole) (PNVI) brushes up to 550 nm are directly created onto TiO2 via UV-induced photopolymerization of corresponding monomers. Kinetic studies reveal a linear increase in thickness wit...

Dynamic Self-Assembly Induced Rapid Dissolution of Cellulose at Low Temperatures
Cellulose can be dissolved in precooled (-12 °C) 7 wt % NaOH-12 wt % urea aqueous solution with in 2 min. This interesting process, to our knowledge, represents the most rapid dissolution of native cellulose.The results from 13C NMR, 15N NMR, 1H NMR, FT-IR, small-angle neutron scattering (SANS), transmission electron microscopy (TEM), and wide-angle X-ray diffraction (WAXD) suggested ...

Nanocomposite hydrogels with rapid thermal-responsibility by using surfactant detergent as template
To improve thermal-responsibility of poly N-isopropylacrylamide/inorganic hectorite hydrogels, inorganic hectorite severed as physical cross-linker, a kind of nonionic surfactant detergent polyoxyethylene 20 cetyl ether (POECE) was used as template to prepare nanostructured hydrogels (THPN hydrogels). The structure, morphology, temperature-sensitivity and swelling behavior of THPN hydrogels were&n...

A 1,8-naphthyridine-based fluorescent chemodosimeter for the rapid detection of Zn2+ and Cu2+
A novel fluorescent chemodosimeter based on 1,8-naphthyridine exhibits high selectivity to Zn2+ and Cu2+. When 1-(7-acetamino-1,8-naphthyridyl)-
2-(6-diacetaminopyridyl)ethene was mixed with CuCl2, hydrolysis of the acetamino group catalyzed by Cu2+ complex was first observed.
Resulting from coordination and hydrolysis catalyzed by the corresponding complex of Zn2+ or Cu2+, the highly effective ...

Synthesis, characterization and the rapid response property of the temperature responsive PVP-g-PNIPAM hydrogel
In this study, a poly(N-vinylpyrrolidone)-graft-poly(N-isopropylacrylamide) hydrogel
(PVP-g-PNIPAM) was synthesized through the ‘‘grafting from” process. Grafting of temper-
ature responsive poly(N-isopropylacrylamide) (PNIPAM) brushes was carried out from the
poly(N-vinylpyrrolidone) (PVP) synthesized with free radical polymerization and function-
alized with ATRP initiator,...

Rapid and reversible hydrogen storage in clathrate hydrates using emulsion-templated polymers
A method for greatly accelerating the storage of gases such as hydrogen in clathrates by supporting the clathrate phase on a highly macroporous emulsion-templated polymer is presented. The gravimetric penalty is low due to the low bulk d. of the support, no mech. mixing is required, and the system is fully recyclable over multiple charge/discharge cycles.
