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...

Concentric Hollow Nanospheres of Mesoporous Silica Shell-Titania Core from Combined Inorganic and Polymer Synthesis
Nearly monodispersed concentric hollow nanospheres with a mesoporous silica shell and anatase titania inner core were synthesized by the combination of sol-gel reaction and distillation-precipitation polymerization. The welldefined mesoporous concentric hollow nanospheres, comprising two nanostructured functional inorganics, can be used
for confined catalytic reactions. The direct synthesis proced...

pH-Responsive hollow polymeric microspheres and concentric hollow silica microspheres from silica-polymer core-shell microspheres
Nearly monodispersed silica-poly(methacrylic acid) (SiO2-PMAA) core-shell microspheres were synthesized by distillation-precipitation polymerization from 3-(trimethoxysilyl)propylmethacrylate-silica (SiO2-MPS) particle templates. SiO2-PMAA-SiO2 trilayer hybrid microspheres were subsequently prepared by coating of an outer layer of SiO2 on the SiO2-PMAAcore-shell microspheres in a sol-gel process. ...

Synthesis of Core-corona Polymer Hybrids with Raspberry-like Structure via Heterocoagulated Pyridinium Reaction
A core-corona polymer hybrid with a raspberry-like structure was synthesized via the heterocoagulated pyridium reaction between the pyridyl group of poly(ethylene glycol dimethacrylate-co-methacrylic acid)@poly(ethylene glycol dimethacrylate-co- vinylpyridine) (poly(EGDMA-co-MAA)@poly(EGDMA-co-VPy)) core-shell small microspheres and the chloromethyl group of poly(divinylbenzene-co-chloromethyl sty...

Core-corona Polymer Composite Particles by Self-assemble Heterocoagulation Based on A Hydrogen-bonding Interaction
Poly(ethylene glycol dimethacrylate-co-acrylic acid) (poly(EGDMA-co-AA)) small microspheres were effectively self-assembled on oly(ethylene glycol dimethacrylate-co-4-vinylpyridine) (poly(EGDMA-co-VPy)) surfaces to form a core-corona structure with a raspberry-like polymer composite by a hydrogen interaction mechanism through an affinity complex between the carboxylic acid group and pyridine group...

A facile method for synthesis of Fe3O4@Polymer microspheres and their application as magnetic support for loading metal nanoparticles
In this Article, a facile and general method was afforded to prepare magnetite/polymer coreshell microspheres. The hydrogen bond interaction between the magnetite and a series of functional monomers was strong enough for coating polymer shells onto the magnetite microspheres. Various functional shells such as carboxyl, hydroxyl, amide, and ester were provided via the tune of the monomer during th...
