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...

Multi-layer Magnetic Composite Particles with Functional Polymer Brushes as Stabilizer for Gold Nanocolloids and Their Recyclable Catalysis
Multifunctional Fe3O4@SiO2@PHEMA-g-PDMAEMA microspheres with magnetic core and polymer brushes were prepared via a successive process, which combined the solvothermal
method and sol?gel technique for the synthesis of inorganic core with DPP and ATRP for the preparation of the outer polymer shell. The gold nanoparticles were facilely loaded onto
the multifunctional microspheres by the in situ reduc...

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...

Facile Synthesis of Hollow Polymer Microspheres with Movable Cores with the Aid of Hydrogen-bonding Interaction
Poly(divinylbenzene-co-acrylic acid) (poly(DVB-co-AA)) hollow microspheres with movable poly(DVB-co-AA) cores were prepared by a facile route. In this approach, poly(DVB-co-AA) microspheres were first used as templates to synthesize poly(DVB-co-AA)@PAA core-shell particles with a non-crosslinked PAA shell by distillation precipitation polymerization in acetonitrile. In situ polymerization to prepa...

Hybrid Nanorattles of Metal Core and Stimuli-Responsive Polymer Shell for Confined Catalytic Reactions
Narrowly-dispersed silver@silica@poly(methacrylic acid) (Ag@SiO2@PMAA) core–double shell hybrid nanoparticles (NPs) were first synthesized by distillation–precipitation polymerization, using silver@silica core–shell NPs from the sol–gel reaction as templates. Selective removal of the inorganic silica inner-shell from the Ag@SiO2@PMAA core–double shell hybrid NPs by HF etching produces the Ag@...
