Synthesis of Monodisperse Titania/Polymer Core-shell Hybrid Microspheres
Monodisperse titania/polymer core-shell microspheres were prepared by a two-stage reaction with titania as core and poly(ethyleneglycol dimethacrylate) (PEGDMA)
as shell, in which the titania cores were synthesized by a sol-gel method and subsequently grafted with 3-trimethoxysilyl methacrylate as the first-stage reaction to incorporate the vinyl groups on the surface of inorganic core. The PEGDMA...

Synthesis of Hollow Fluorescent Polymer Microspheres with Movable Magnetic Cores
Low-dispersity hollow poly[(ethyleneglycol dimethacrylate)-co-(N-vinylcarbazole)] (P(EGDMA-co-NVCz)) fluorescent microspheres with movable magnetic cores were prepared by quantitative removal of the silica component in hydrofluoric acid aqueous solution from the corresponding magnetite/silica/P(EGDMA-co-NVCz) tri-layer hybrid microspheres. The tri-layer microspheres with magnetic cores and fluores...

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 ...

[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...
