Monodisperse Temperature-responsive Hollow Polymer Microspheres: Synthesis, Characterization and Application
Temperature-responsive hollow poly(N-isopropylacrylamide) (PNIPAAm) microspheres were prepared by a two-stage distillation precipitation polymerization to afford a core–shell microspheres with subsequent removal of poly(methacrylic acid) (PMAA) core. PMAA@PNIPAAm core–shell microspheres were synthesized by the second-stage polymerization of NIPAAm in the presence of PMAA as core with N,N0-
methy...

Exfoliated Graphite Oxide Decorated by PDMAEMA Chains and Polymer Particles
Exfoliated graphite oxide (GO) sheets with hydroxyl groups and amine groups on the surface were prepared by modification of graphite. Atom transfer radical polymerization (ATRP) initiator molecules were grafted onto the GO sheets by reactions of 2-bromo-2-methylpropionyl bromide with hydroxyl groups and amine groups. Poly-(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) chains on the surface of GO ...

Polyethyleneimine functionalized polymer microsphere: A novel delivery vector for cells
Monodisperse poly(ethylene glycol dimethacrylate-co-methacrylic acid) (P(EGDMA-co-MAA)) microspheres with two different diameters (69 and 160 nm) were facilely synthesized via distillation precipitation polymerization in neat acetonitrile, and these microspheres interacted with the amino groups of polyethyleneimine (PEI) chains though hydrogen-bonding as well as electrostatic interactions to form ...

Synthesis of Hollow Polymer Microspheres with Gold Nanoparticle-functionalized Movable Core
Hollow poly(ethyleneglycol dimethacrylate) (PEGDMA) microspheres with Au nanoparticle
functionalized movable cores were prepared by selective removal of the sandwiched silica mid-layer from the corresponding poly(ethyleneglycol dimethacrylate-co-methacrylic acid)/poly(ethyleneglycol dimethacrylate-co-vinylpyridine)@gold/silica/PEGDMA (P(EGDMA-co-MAA)/P(EGDMA-co-VPy)@Au/SiO2/PEGDMA) tetra-layer com...

[ACS Appl. Mater & Interf.] Hydroxylation of Organic Polymer Surface: Method and Application
It may be hardly believable that inert C–H bonds on a polymeric material surface could be quickly and efficiently transformed into C–OH by a simple and mild way. Thanks to the approaches developed recently, it is now possible to transform surface H atoms of a polymeric substrate into monolayer OH groups by a simple/mild photochemical reaction. Herein the method and application of this small-mo...

Porogen on the Rosin-Based Porous Polymer Microspheres and Adsorptions for Phenol Solution
The porous polymer microspheres with rosin
moiety were prepared by suspension polymerization, using an ester (RH) of rosin
and 2-hydroxyethyl methacrylate, along with styrene (St) as
monomers, divinylbenzene (DVB) as cross-linking agent, gelatin as the
dispersing agent, and azodiisobutyronitrile (AIBN) as initiator. The
effects of types and levels of porogen on the porous microsphere w...

Preparation of Polymer Microspheres with a Rosin Moiety from Rosin Ester, Styrene, and Divinylbenzene
Rosin
was reacted with hydroxyethyl methacrylate to produce a macromonomer. This macromonomer
was used to replace styrene partly for the novel preparation of polymer
microspheres with divinylbenzene via suspension polymerization. Orthogonal experiments were conducted to analyze the
factors influencing the particle size, particle size distribution, swelling
ratio, and degree of crosslinking of the ...

Parallel Carbon Nanotube Stripes in Polymer Thin Film with Remarkable Conductive Anisotropy
In our previous study (Mao et al. J. Phys. Chem. Lett. 2013, 4,
43?47), we proposed a novel method, that is, the shear-flow-induced
hierarchical self-assembly of two-dimensional fillers (octadecylamine-functionalized
graphene) into the well-ordered parallel stripes in a polymer matrix, to
fabricate the anisotropic conductive materials. In this study, we extend this
method to one-dimensional multiw...

107.Covalent immobilization of a polyoxometalate in a porous polymer matrix: a heterogeneous catalyst towards sustainability
The heterogenization of a polyoxometalate (POM) catalyst by direct covalent immobilization in polymer matrices with uniform macropores and high specific surface areas was reported. Via click chemistry, organically modified POM clusters were mainly “clicked” on the functionalized channel surface of a macroporous resin. The appraisement of the catalytic performance via catalysis on tetrahydrothiop...
