Synthesis of Ellipsoidal Hematite/Silica/Polymer Hybrid Materials and the Corresponding Hollow Polymer Ellipsoids
Ellipsoidal trilayer hematite/silica/poly(divinylbenzene) hybrid particles were prepared by distillation precipitation polymerization of divinyl benzene (DVB) in the presence of hematite/3-(methacryloxy)propyl trimethoxysilane (MPS)-modified silica (SiO2) core-shell particles as the seeds. The polymerization of DVB was performed in neat acetonitrile
with 2,2′-azobisisobtyronitrile (AIBN) as initi...

[Materials Chemistry and Physics] Controlled growth of metal nanoparticles on amino-functionalized polystyrene microspheres and their application in surface-enhanced Raman spectroscopy
This paper describes the preparation of hybrid materials of metallic nanoparticles (NPs) coated amino-terminated polystyrene (PS-NH2) microspheres by seed-mediated growth technique, and their application in surface-enhanced Raman spectroscopy (SERS). In our approaches, monodisperse PS microspheres are firstly prepared using dispersion polymerization with a subsequent nitration and amination to ach...

Polydiacetylene-Polymethylmethacrylate/Graphene Composites as One-Shot, Visually Observable, and Semiquantative Electrical Current Sensing Materials
Aiming to develop pH-paper-like current sensing materials, we prepared irreversible electrochromic PDA-PMMA/graphene composites. The composites exhibited an excellent linear relationship between critical responsive currents and the amount of graphene in the system. In these composites, PDA acted as the electrochromic material and graphene as the conductive matrix. The presence of PMMA not only ens...

Hematite Nanostructures Synthesized by Silk Fibroin-Assisted Hydrothermal Method. Journal of Materials Chemistry B, 2013, 1(2): 213-220
A green, simple and economical route based on an efficient Bombyx mori silk fibroin assisted hydrothermal process has been developed to synthesize monodisperse hematite (alpha-Fe2O3) nanostructures with fine shape control. The effects of reaction time and silk fibroin concentration on the morphology of alpha-Fe2O3 have been investigated systematically. Several morphologies including quasi-nanocube...

A Hierarchical Adsorption Material by Incorporating Mesoporous Carbon into Macroporous Chitosan Membrane. Journal of Materials Chemistry, 2012, 22(24): 11908-11911
An easy and practical method is adopted to assemble mesoporous carbon particles into a macroporous chitosan membrane to form hierarchical adsorption membranes for water treatment. The membrane showed both good static and dynamic adsorption properties on model dye fuchsin, which implies its great potential for decontamination in flowing systems.
