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

Permeability, viscoelasticity, and flammability performances and their relationship to polymer nanocomposites
Despite abundant studies on gas barrier, viscoelastic, and flammability properties of polymer nanocomposites, comprehensive understandings of these performances and their relationships are still lacking. We herein attempt to gain deep insights into the performances by creating several polymer nanocomposites by incorporating three types of nanoparticles, nanoclay (Clay), carbon nanotubes (CNTs), an...

Compact PEGylated polymer-caged quantumdots with improved stability
Compact PEGylated polymer-caged quantumdots were prepared by covalently cross-linking the surface ligands using bifunctional poly(ethylene glycol). CdSe/ZnSe/ZnS quantumdots prepared in organic solvent via conventional synthesis method were firstly transferred to water phase by surface ligands exchange with glutathione molecules, and then cross-linked by bifunctional PEG through the carboxyl-amine...

[J. Am. Chem. Soc.] Polymer Brushes on Graphene
A critical bottleneck for the widespread use of single layer graphene is the absence of a facile method of chemical modification which does not diminish the outstanding
properties of the two-dimensional sp2 network. Here, we report on the direct chemical modification of graphene by photopolymerization with styrene. We demonstrate that photopolymerization occurs at existing defect sites and that ...

Direct Electrochemical Generation of Conducting Polymer on Silicon Substrate.
Abstract: Polypyrrole microcontainers with morphology like bowls, cups, goblets and bottles have been electrochemically generated by direct oxidation of pyrrole on a p-type silicon wafer in aqueous solution of camphorsulfonic acid. The well-ordered microcontainers stand upright on the working electrode surface and changing the electrochemical polymerization conditions can easily control their morp...
