/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...

Catalytic properties
of
carboxylic acid functionalized-polymer microsphere-stabilized gold metallic colloids
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
pH and salt electrolyte on the...

Monodisperse
Polymer
Microspheres with Mercapto Groups and Their Application as Stabilizer for Gold Metallic Colloid
Monodisperse polymer microspheres with functional mercapto groups on the surface were prepared from poly[(ethylene glycol dimethacrylate)-co-(2-hydroxyethyl methacrylate)], poly(EGDMA-co-HEMA), microspheres successively through esterification
of
the active hydroxyl groups with acryloyl chloride to introduce carbon-carbon double bonds and then the addition reaction
of
hydrogen sulfide to the double...

Enhancing the sulfonated poly(ether ether ketone) membrane performances by incorporating myulti-functional polymer spheres
The composite membranes were fabricated by physical blending
of
sulfonated poly(ether ether ketone) (SPEEK) bulk material and crosslinked polymer carboxylic acid spheres (PCASs) with diameter
of
150 nm, which were prepared by distillation–precipitation copolymerization
of
ethyleneglycol dimethacrylate (EGDMA) crosslinker and functional methacrylic acid (MAA) monomer. The incorporation
of
PCASs in...

Enhancing water retention and low-humidity proton conductivity
of
SPEEK composite membrane enabled by the polymer-microcapsules with controllable hydrophilicity-hydrophobicity
Four kinds
of
polymer microcapsules (PMCs) with different hydrophilicityehydrophobicity are synthesized via distillationeprecipitation polymerization (polymer microcapsules form by self-crosslinking
of
monomers/crosslinkers in this process) and incorporated into sulfonated poly(ether ether ketone) (SPEEK) matrix to prepare composite membranes. To improve the water retention
of
the PMCs, the hydrop...

Tuning the performance
of
DMFC membranes by embedding multifunctional functionalized inorganic microspheres into polymer matrix
A series
of
surface functionalized silica submicrospheres by distillation–precipitation polymerization were embedded into chitosan (CS) matrix to fabricate the hybrid membranes for direct methanol fuel cell (DMFC). SEM characterization indicated that the submicrospheres could disperse homogenously within the CS matrix via tuning the polymer/particle and particle/particle interfacial interactions....

Microspheres with pH-Sensitivity for Anticancer Drug-carriers
The hollow poly(N,N0-methylenebisacrylamide-co-methacrylic acid) (P(MBAAm-co-MAA)) microspheres were prepared by the selective removal
of
poly(methacrylic acid) (PMAA) core from the corresponding PMAA/P(MBAAm-co-MAA) core-shell microspheres, which were synthesized via a two-stage distillation precipitation polymerization. The magnetic Fe3O4 nanoparticles onto the surface
of
hollow P(MBAAm-co-MAA) ...
