Tunable nanochannels through graphene oxide/polymer core-shell nanosheets for enhanced proton conductivity
Simultaneous manipulation of the topological
structure and chemical structure of the ionic nanochanels within solid electrolyte has
been proved a crucial but challenging task for the rational design of high-performance
electrochemical devices including proton exchange membrane fuel cell. Herein,
we present a novel approach to the construction of tunable nanochannels via direct assembly of graphene...

Preparation of monodisperse bimetallic nanorods with gold nanorod core and silver shell and their plasmonic property and SERS efficiency
In this study, monodisperse bimetallic nanorods with gold (Au) nanorod core and silver (Ag) shell (Au@AgNRs) were synthesized through seed-mediated growth process by reduction of AgNO3 using Au nanorods with narrow size and shape distribution as seeds. With increasing the used amount of AgNO3, the Ag shell thickness of their lateral facets is raised faster than that of their two tips, leading to a...

Self-Assembly of Star Micelle into Vesicle in Solvents of Variable Quality: The Star Micelle Retains Its Core–Shell Nanostructure in the Vesicle
Intra- and inter-molecular interactions of star polymers in dilute solutions are of fundamental importance for both theoretical interest and hierarchical self-assembly into functional nanostructures. Here, star micelles with a polystyrene corona and a small ionic core bearing platinum(II) complexes have been regarded as a model of star polymers to mimic their intra- and inter-star interactions and...

Preparation of Core-Shell Nanofibers with Selectively Localized CNTs from Shish Kebab-like Hierarchical Composite Micelles
A novel and facile bottom-up strategy for preparing core-shell nanofibers with selectively localized carbon nanotubes is developed using hierarchical composite micelles of crystalline-coil copolymer and carbon nanotubes as the building blocks. An amphiphilic di-block copolymer of poly (p-dioxanone) (PPDO) and PEG (polyethylene glycol) functionalized with pyrene moieties at the chain ends of P...

Robust microcapsules with polyurea/silica hybrid shell for one-part self-healing anticorrosion coatings
Silica/polyurea hybrid microcapsules loaded with hexamethylene diisocyanate (HDI) as core materials were prepared via a combined strategy of interfacial polymerization and an in situ sol-gel process in an oil-in-water emulsion. They were clearly characterized by scanning electron microscopy. Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The resultant microcapsule...

Nanofibers with Very Fine Core-Shell Morphology from Anisotropic Micelle of Amphiphilic Crystalline-Coil Block Copolymer
A novel and facile strategy, combining anisotropic micellization of amphiphilic crystalline-coil copolymer in water and reassembly during single spinneret electrospinning, was developed for preparing nanofibers with very fine core shell structure. Polyvinyl alcohol (PVA) and polyethylene glycol-block-poly(p-dioxanone) (PEG-b-PPDO) were used as the shell and the crystallizable core layer, respect...

One-Pot Synthesis of Highly Magnetically Sensitive Nanochains Coated with a Fluorescent Shell by Magnetic-Field-Induced Precipitation Polymerization
One-dimensional (1D) magnetic fluorescent Fe3O4/P(GMA-EGDMA-NVCz) peapod-like nanochains have been successfully synthesized by magnetic-field-induced distillation precipitation polymerization. Fe3O4 microspheres can be arranged with the direction of external magnetic field in a line via the dipolar interaction between Fe3O4 microspheres and linked permanently via P(GMA-EGDMA-NVCz) coat...

Effect of carboxyl density at the core–shell interface of surface-imprinted magnetic trilayer microspheres on recognition properties of proteins
A novel protein surface-imprinted magnetic trilayer composite microsphere (Fe3O4@HEA@protein-MIPs) was designed and prepared. The objective of this study was to study the effect of carboxyl density at the core–shell interface on recognition performance. The imprinting process was carried out on the surface of Fe3O4@hydroxyethyl acrylate (Fe3O4@HEA) microsphere modified by maleic anhydride (MAH)...

Synthesis of Poly(methacrylic acid)-MnO(OH)2/SiO2 Core-shell and the Corresponding Hollow Microspheres Containing Mn2O3
Poly(methacrylic acid)-MnO(OH)2/SiO2 core-shell microspheres were prepared by the sol-gel hydrolysis of tetraethylorthosilicate
