[Advanced Functional Materials] Manipulating the Motion of Gold Aggregates Using Stimulus Responsive Patterned Polymer Brushes as Motor
An important goal and major challenge of material science and nanotechnology
is building nanomotors for manipulating the motion of nanoparticles (NPs). Here, it is demonstrated that patterned, stimulus-responsive polymer brush microstructures can be used as motor arrays to manipulate the movement of gold NP aggregates in response to external stimuli that induce a conformational change in the bru...

Journal of Materials Chemistry 2011: Dendrimer modified magnetic iron oxide nanoparticle/DNA/PEI ternary magnetoplexes: a novel strategy for magnetofection
As a powerful technology to enhance the efficiency of gene delivery, magnetofection has attracted considerable attention in the past decade. In this work, we introduced 6 generation of PAMAM dendrimer modified superparamagnetic nanoparticles (DMSPION-G6) to PEI/DNA polyplexes by a two-step process and enhanced the transfection efficiency of PEI with the help of a magnetic field. We prepared DMSPIO...

Acid blue AS doped polypyrrole (PPy/AS) nanomaterials with different morphologies as electrode materials for supercapacitors
Accepted Man
The polypyrrole (PPy) nanomaterials with different morphologies were prepared via
the chemical oxidative polymerization of pyrrole in the presence of acid blue AS (AS)
as the dopant and surfactant. Increasing of the feeding ratio of AS, the morphology of
the resultant acid blue AS doped polypyrrole (PPy/AS) nanomaterials changed from
nanoparticles to clusters of nanofibers and...

Adv. Mater., 2011, 23, 2134-2148: An Emerging Pore-Making Strategy: Confined Swelling-Induced Pore Generation in Block Copolymer Materials
Block copolymers (BCPs) composed of two or more thermodynamically incompatible homopolymers self-assemble into periodic microdomains. Exposing self-assembled BCPs with solvents selective to one block causes a swelling of the domains composed of this block. Strong swelling in the confinement imposed by the matrix of the other glassy block leads to well-defined porous structures via morphology recon...

[Advanced Materials] Organic/inorganic Hybrid Hollow Spheres Prepared from TiO2-stabilised Pickering Emulsion Polymerization
Organic/inorganic hybrid hollow spheres are prepared from TiO2-stabilized Pickering emulsion polymerization. By self-organization of TiO2 nanoparticles at the interface of oil (monomer and solvent) and water, O/W colloidosomes are formed as polymerization vessels to obtain organic/inorganic hybrid hollow spheres. The diameter and mechanical stability of hybrid hollow spheres can be tailored ...

[Polymer] Confined photo-catalytic oxidation: a fast surface hydrophilic modification method for polymeric materials
When a very thin persulfate salt aqueous solution layer (mum) was sandwiched between two polymer films and strong UV light irradiated the assembly from the side transparent to UV light, a fast surface hydrophilic modification method for most of commercial polymeric materials was developed. For example, irradiating for 90 s and using 30 wt% ammonium persulfate, the static surface water conta...

Advanced Materials 2007: A cleavable-polycation template method for the fabrication of noncrosslinked, porous polyelectrolyte multilayered films
Porous, noncrosslinked polyelectrolyte-complex thin films (see figure), which will find applications in biomedicine, for example for drug or gene delivery, are achieved by using a simple, mild, and efficient method. Layer-by-layer assembly of polyanion and a blend of two polycations is followed by removal of the reductively degradable polycation template in the multilayered film in dithiothreitol ...

Emulsion-templated porous materials using concentrated carbon dioxide-in-water emulsions and inexpensive hydrocarbon surfactants
Supercrit. carbon dioxide is the most extensively studied supercrit. fluid (SCF) medium for polymn. reactions and org. transformations. This can be attributed to a list of advantages ranging from solvent properties to practical environmental as well as economic considerations. In addn., when CO2 is used for the synthesis and processing of porous materials addnl. advantages are also rea...
