Preparation of silica/polymer hybrid microspheres and the corresponding hollow polymer microspheres with functional groups
Monodisperse functional silica/polymer core–shell hybrid microspheres were prepared by a two-stage reaction with silica grafting of 3-(methacryloxy)propyl trimethoxysiliane (MPS) as core and polymer as shell having various functional groups such as chloromethyl, pyridyl, carboxylic acid, hydroxyl, and ester. MPS-modified silica core was synthesized by the Sto¨ber method and subsequently grafted ...

Synthesis of Tri-layer Magnetic Polymer Microspheres with Magnetic core and Functional Polymer Shell
Tri-layer magnetite/silica/poly(divinylbenzene)(Fe3O4/SiO2/PDVB) core-shell hybrid microspheres
were prepared by distillation precipitation polymerization of divinylbenzene (DVB) in the presence of magnetite/3-(methacryloxyl)propyl trimethoxysilane (MPS) modified silica core-shell particles as seeds. The polymerization of DVB was performed in neat
acetonitrile with 2,20-azobisisobutyronitrile (A...

Alternating Silica/Polymer Multi-layer Hybrid Microspheres Templates for Double-shelled Polymer and Inorganic Hollow Microspheres
Alternating silica/polymer tetra- and penta-layer hybrid microspheres were first prepared via combined inorganic sol-gel reaction and distillation-precipitation polymerization. pH-responsive poly(methacrylic acid) (PMAA) hollow microspheres with asymmetric double-shells were produced afterHF etching of the silica layers in the SiO2/PMAAtetra-layer microspheres with different degrees of cross-linki...

RAFT dispersion polymerization of styrene in water/alcohol: the solvent effect on polymer particle growth during the polymer chain propagation
The RAFT polymerization of styrene in a solvent consisting of a water/alcohol mixture with different water contents is performed and the solvent effects on polymerization kinetics, polymer chain propagation, and polymer particle growth are evaluated. It is found that the solvent affects the RAFT polymerization kinetics greatly, and the apparent polymerization rate constant (Kp app) increases wit...

[Progress in Polymer Science] Stimulus-responsive polymer brushes on surfaces: Transduction mechanisms and applications
Stimulus-responsive polymer brushes (SRPBs) exhibit a change in conformation and structure, often accompanied by a noticeable change in surface energy, due to an external stimulus such as a change in solvent composition, temperature, pH, ionic strength, light, or mechanical stress. SRPBs offer exciting andnewpossibilities to fabricate adaptive or responsive smart materials. This review summarize...

Cellulose acetate polymer film modified microstructured polymer optical fiber towards a nitrite optical probe
A novel microstructured polymer optical fiber (MPOF) probe for nitrites (NO2−) detection was made by forming rhodamine 6G (Rh 6G)-doped cellulose acetate (CA) on the side wall of array holes in a MPOF. It was found that the MPOF probe only have a response to nitrites in a certain concentration of sulfuric acid solution. The calibration graph of fluorescence intensity versus nitrites concentr...

[Anal. Chem.] Thickness measurement of nanoscale polymer layer on polymer substrates by attenuated total reflection infrared spectroscopy
For the first time, attenuated total reflection (ATR)-Fourier transform infrared (FT-IR) spectroscopy was utilized to measure the thickness (d(0)) of a nanoscale polymer layer on polymer substrate with significant credibility. First, a mathematical formula, A/A(0) = 1 - 2d(0)/d(p), was derived based on a self-defining subsection function (where d(p) was defined as depth of penetration of AT...
