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@...

Enhancement of Proton Conduction at Low Humidity by Incorporating Imidazole Microcapsules into Polymer Electrolyte Membranes
Design and fabrication of hierarchically structured membranes with high
proton conductivity is crucial to many energy-relevant applications including
proton exchange membrane fuel cell (PEMFC). Here, a series of imidazole
microcapsules (IMCs) with tunable imidazole group loading, shell thickness,
and lumen size are synthesized and incorporated into a sulfonated poly(ether
ether ketone) (SPEEK) mat...

Enhancing the water uptake and retention of membrane by embedding polymer hollow spheres as the water reservoirs
Water retention is a pervasive issue in agriculture and industry. Inspired
by the water-storage mechanisms in plant cells, three kinds of polymeric
microcapsules (PMCs) with carboxylic acid, sulfonic acid, and pyridyl groups
are prepared using distillation–precipitation polymerization. The size of the
lumen of the PMCs may govern the static water uptake by holding water
molecules in a free-water ...

Low Cationic Proportion Ampholytic Polymer: Synthesis, Solution Properties and Interaction with Anionic Surfactant.
Novel ampholytic terpolymer of N-vinylformamide (NVF), vinylamine (VAm) and sodium acrylate (NA) with low cationic proportion was obtained by hydrolyzing copolymer of NVF and NA (PNVFNA). Solution properties of the polymer were investigated by methods of turbidity and viscosity experiment. The effect of sodium dodecyl sulfate (SDS) on solution viscosity was also investigated. The results showed th...

Photoenhanced gene transfection by a star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms
A star-shaped polymer (PP-PLLD) consisting of a porphyrin (PP) core and poly(L-lysine) dendron arms (PLLD) is synthesized by the click reaction, and its ability to deliver pEGFP is investigated in this paper. It is found that PP-PLLD has a good buffer capacity and can form compact complexes with pEGFP. In vitro assay indicates that PP-PLLD shows photoenhanced gene transfection efficiency. PP-PLLD ...
