Understanding the effect of chain entanglement on the glass transition of a hydrophilic polymer
In this article, we report an interesting phenomenon of the glass transition temperature (Tg) deviation of a hydrophilic polymer. Polyacrylamide (PAL) samples with different extents of chain entanglement were prepared by spray drying and solution casting. We found that the glass transition temperature increases as the extent of chain entanglement decreases upon the sub-Tg annealing. The...

Biodegradable nano-composite polymer scaffolds for bone tissue engineering
Although hydroxyapatite (HA) ceramics has good osteoconductivity and osteoinductivity, the brittleness and fatigue failure in the body limit their clinical applications. Recent development of biodegradable polymers, mainly polyesters such as poly(L-lactic acid ) (PLLA), poly(glycolic acid) (PGA) and their copolymers (PLGA), is an attractive approach for tissue engineering with a wide rang...

[Macromol. Rapid Commun.] Polymer Brushes on Planar TiO2 Substrates
A facile and universal method is presented for the preparation of polymer brushes on amorphous TiO2 film. Homogeneous and stable poly(methyl methacrylate), polystyrene, poly(4-vinylpyridine), and poly(N-vinyl imidazole) (PNVI) brushes up to 550 nm are directly created onto TiO2 via UV-induced photopolymerization of corresponding monomers. Kinetic studies reveal a linear increase in thickness wit...

Hydrogenation of o-Chloronitrobenzene over Polymer-stabilized Palladium-Platinum Bimetallic Colloidal Clusters
Hydrogenation of o-chloronitrobenzene o-CNB. has been studied in methanol at 303 K and atmospheric pressure over polyvinylpyrrolidone-stabilized palladium–platinum PVP-PdrPt. bimetallic colloidal clusters. The catalytic properties for the hydrogenation of o-CNB to o-chloroaniline o-CAN. are found to depend on the metal composition of the bimetallic
clusters. All the bimetallic clusters are mor...

Synthesis of Monodisperse CdS/SiO2/Polymer Tri-layer Fluorescent Microspheres
Tri-layer CdS/SiO2/polymer hybrid nanospheres were synthesized by distillation precipitation polymerization of either ethyleneglycol dimethacrylate (EGDMA) or EGDMA together with comonomers having different functional groups, such as methacrylic acid, 4-vinylpyridine and 2-hydroxyethylmethacrylate, in the presence of 3-(methacryloxy)propyl trimethoxysilane (MPS)-modified CdS/SiO2 nanoparticles a...
