Raspberry-like Core-corona
Polymer
Composite Particles via Electrostatic Self-assembled Heterocoagulation
Nano-sized poly(ethyleneglycol dimethacrylate-co-sodium acrylate) (poly(EGDMA-co-AcNa)) particles were effectively self-assembled on poly(divinylbenzene-co-styrylmethyl trimethyl ammonium chloride) (poly(DVB-co-StMTMACl)) surfaces to result in core–corona composite particles with a raspberry-like structure by an electrostatic interaction through an affinity complex between sodium acrylate and qua...

Raspberry-like
Polymer
/Silica Core-Corona Composite by Self-assemble Heterocoagulation Based on A Hydrogen-bonding Interaction
Raspberry-like poly(ethyleneglycol dimethacrylate-co-4-vinylpyridine)/silica (poly(EGDMA-co-VPy)/SiO2) core-corona composite was prepared by a self-assemble heterocoagulation based on a hydrogen-bonding interaction between the pyridyl group
of
poly(EGDMA-co-VPy) core and the active hydroxyl group
of
silica corona. The raspberrylike composite was stable near the neutral environment with pH ranging ...

Microspheres Containing Gold-nanocolloid Core Adsorbed on the Inner-surface as A Catalytic Microreactor
Hollow polymer microspheres with different polarity and functional group for the shell layer containing gold nanocolloid cores adsorbed on the inner surface were prepared by selective removal
of
sandwiched silica layer from the corresponding gold/silica/polydivinylbenzene (Au/SiO2/PDVB), Au/SiO2/poly(ethyleneglycol dimethacrylate) (Au/SiO2/PEGDMA), and Au/SiO2/poly(ethyleneglycol dimethacrylate-co...

Microspheres with Functional Groups on the Shell Layer by Two-stage Distillation-precipitation
Polymer
ization
Monodisperse crosslinked core–shellmicrometer-sizedmicrospheres bearing a brightly blue fluorescent dye, carbazole, and containing various functional groups in the shell layers were prepared by a two-stage distillation–precipitation polymerization in acetonitrile in the absence
of
any stabilizer. Commercial divinylbenzene (DVB), containing 80 vol.%
of
DVB, was polymerized by distillation–precip...

Microspheres with Active Hydroxyl Group by Distillation-precipitation
Polymer
ization
Narrow-dispersion or monodisperse polymer microspheres with active hydroxyl groups were prepared by distillation–precipitation polymerization in the absence
of
any stabilizer. The monomer hydroxyethyl methacrylate (HEMA) was copolymerized with either commercial divinylbenzene (DVB) (containing 80 %
of
DVB isomers) or ethyleneglycol dimethacrylate (EGDMA) as crosslinker by distillation–precipitat...

/ZrO2 Core-shell Microspheres and the Corresponding Hollow Porous Zirconia Microspheres
Narrow-disperse poly(N,N0-methylenebisacryamide-co-methacrylic acid)/zirconium hydroxide (P(MBA-co-MAA)/Zr(OH)4) coreeshell composite microspheres were synthesized by the controlled sole-gel hydrolysis
of
inorganic zirconium n-butoxide (Zr(OBu)4) precursor in ethanol and acetonitrile mixed solvent with P(MBA-co-MAA) microspheres as templates. The thickness
of
the outer inorganic Zr(OH)4 shell-laye...

Polymer
Shell as A Protective Layer for Sandwiched Gold Nanoparticles and Their Highly Stable Catalytic Property
Poly(ethyleneglycol methacrylate) (PEGDMA) shell was used as a protective layer for the sandwiched gold nanoparticles, which were prepared through the in situ reduction in the HAuCl4 precursor in the presence
of
(aminopropyl)trimethoxysilane (APS) modified silica/PEGDMA core–shell microspheres. In this process, the silica/PEGDMA core–shell microspheres were afforded by the distillation-precipita...

Size-controlled Gold Nanocolloids on
Polymer
Microsphere-stabilizer via Interaction Between Functional Group and Gold Atoms
Gold nanocolloids with the controlled diameter ranging from 5.2 to 10.7 nm were in situ prepared by reduction
of
gold chloride trihydrate with sodium borohydride as reductant via the interaction between the gold naocolloids and the functional groups on the surface
of
polymer microspherestabilizer. The nature
of
such interaction was studied in detail by X-ray photoelectron spectroscopy (XPS). The e...

Polymer
-microsphere-stabilized gold metallic colloids have been prepared by a novel strategy
of
simple and convenient reduction
of
the metallic salt through the stabilization
of
the active carboxylic acid group on the gel and surface layer
of
the microsphere. The nature
of
the interaction between the carboxylic acid and Au nanoparticles was studied in detail by XPS. Preliminary results indicate th...

Raspberry-like Composite
Polymer
Particles by Self-assemble Heterocoagulation Based on A Charge Compensation Mechanism
Nano-sized poly(ethylene glycol dimethacrylate-co-acylic acid) (poly(EGDMA-co-AA)) were effectively self-assembled on poly(divinylbenzene-co-styryl methylpyridinium chloride) (poly(DVB-co-StMPyCl)) surfaces to form the raspberry-like composite by a charge compensation mechanism through the affinity complex between carboxylic group and pyridinium group. The effects
of
