pH-Controlled Reversible Formation of a Supramolecular Hyperbranched Polymer Showing Fluorescence Switching
A pi-conjugated AB(2) monomer 1 with a dibenzo[24]crown-8 (DB24C8) ring and two secondary amine centres has been synthesised. Treatment of a solution of 1 in dichloromethane with trifluoroacetic acid (TFA) leads to protonation of the amine groups, and then the DB24C8 rings are threaded by the dialkylammonium ion centres of other monomer molecules, leading to the formation of a supramolecular hyp...

Synthesis of Multifunctional Microspheres Having Polymer Brush with Magnetism, Fluorescence and pH-Responsiveness
Multifuctional magnetite@silica-fluorescein isothioxylate-g-poly(dimethyl amino ethyl methacrylate)
(Fe3O4@SiO2-FITC-g-PDMAEMA) tri-layer microspheres
with magnetism, fluorescence, and pH-responsive PDMAEMA shell were designed and
prepared. The functional PDMAEMA brush was grafted from Fe3O4@SiO2-FITC
nanoparticles by the surface-induced atom transfer radical polymerization
(SI-ATRP) onto the alky...

Directly Probing molecular ordering at the buried polymer/metal interface
We developed a methodology to directly probe molecular ordering at the buried polymer/metal interface. Using sum frequency generation (SFG) vibrational pectroscopy, we observed ordering of ester methyl groups at the buried poly(methyl acrylate) (PMA)/silver (Ag) interface. In order to directly probe the PMA/Ag interface, we collected SFG signal from a thin PMA film sandwiched between a...

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...
