Late-State Ripening Dynamics of a Polymer/Clay Nanocomposite
A remarkably simple viscoelastic relaxation pattern was found for a physical gel that, beyond its gel point, slowly ripens towards a stable structural state. The material is a nanocomposite that consists of two components, an organo-clay and an end-functionalized polymer, which get mixed at prescribed ratio. When freshly combined, the polymer intercalates into the clay galleries and ev...

A Highly Selective and Sensitive Inorganic/Organic Hybrid Polymer
A polymer based fluorescence “turn-on” chemosensor is demonstrated with high sensitivity and selectivity towards Fe2+ cations. This system is an inorganic/organic hybrid system in which Cu2+ is coordinated at the receptor site of a conjugated polymer sensor. The unique quenching behavior of the Cu2+ towards this conjugated polymer was used to lower the initial fluorescence intensi...

Hydrogen Storage in Microporous Hypercrosslinked Organic Polymer Networks
Hypercrosslinked polymer networks were synthesized by the self-condensation of bischloromethyl monomers such as dichloroxylene (DCX), 4,4'-bis(chloromethyl)-1,1'-biphenyl (BCMBP), and 9,10-bis(chloromethyl)anthracene (BCMA). These materials are predominantly microporous and exhibit BrunauerEmmett-Teller (BET) surface areas of up to 1904 m2/g as measured by N2 adsorption at 77.3 K (Langmuir s...

Dewetting and phase behaviors for ultrathin films of polymer blend.
Dynamics of dewetting and phase separation in ultrathin films (thickness is ca. one radius of gyration, ~ 1 Rg) of poly(methyl methacrylate) (PMMA) and poly(styreneran-acrylonitrile) (SAN) blends on Si substrate has been studied by in situ atomic force microscopy (AFM). In the miscible region, a ‘‘spinodal-like’’ dewetting driven by a composition fluctuation recently predic...

Imaging of elemental distribution at polymer interfaces for studies of adhesion.
The adhesion and fracture of styrene-acrylonitrile random copolymer and poly(methyl methacrylate) (PMMA/SAN) laminates were studied. They showed a drastic transition from brittle to ductile on varying the acrylonitrile (AN) content in SAN, with changes in the fracture mode from interfacial failure to cohesive fracture. Energy-filtering transmission electron microscopy (EFTEM) and scanning electron...

Selective modification of two-dimensional MoS2 nanosheets by polymer grafting
关键字：MoS2, polymer grafting, surface modification
As an emerging two-dimensional (2D) nanomaterial, single layer or a few layers of molybdenum disulfide (MoS2) has drawn significant attention in the past decade. In the present work, we report a strategy in direct creating polymer brushes on MoS2 surfaces via S-C bond in the presence of UV light. The modification of MoS2 nanosheets can be achieved bilaterally or homolaterally by performing the U...

2-Nitrobenzyl Borate Based Photolabile Linker for Breakable Polymer Vesicles
关键字：2-nitrobenzyl ; borate ; PEG-lipid ; photolabile ; polymer vesicles
Fluorescent photolabile groups undergoing convenient synthesis and fast cleavage are being
explored because of their increasing utility in both synthetic and biological chemistry. Herein,
a model photosensitive poly(ethylene glycol)-lipid of NP-B-PEG with a 2-nitrobenzyl 2-pyridinylmethyl
borate hydrophobic tail is synthesized. The 1 H-NMR and absorption spectra analysis
of NP-B-PEG ...

The photodimerization characteristics of anthracene pendants within amphiphilic polymer micelles in aqueous solution
关键字：photodimerization,amphiphilic polymer micelles
An amphiphilic polymer with anthracene pendants of PEO-b-PAM has
been applied to comprehensively investigate the photodimerization
characteristics of anthracene in aqueous solution upon various
selected narrow band of light irradiations in the UV-vis-NIR region.
