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...

Synthesis of 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....

Preparation of Magnetite and Tumor Dual-targeting Hollow Polymer 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) ...

Monodisperse Hydrophilic Polymer Microspheres Having Carboxyl Acid Group by Distillation Precipitation-polymerization
Monodisperse hydrophilic polymer microspheres having carboxyl acid group with spherical shape in the range of 160 nm and 1.52 um were prepared by distillation copolymerizations of (meth)acrylic acid with either ethyleneglycol dimethacrylate (EGDMA) or divinylbenzene (DVB) as crosslinker. Polymerization was carried out with 2,20-azobisisobutyronitrile (AIBN) as initiator in neat acetonitrile withou...
