Studies on Synthesis of Water-Soluble Polymer-supported Transition Metal Polypyridyl Complexes and their interaction with DNA
Five water-soluble polymer-supported transition metal
polypyridyl complexes were synthesized from polyacrylic acid -co-
N-vinyl pyrrolidone, 2-methyl-3-hydroxyl benzaldehyde, o-phenanthroline and
metal acetate salts. Infrared spectra (IR), thermo-gravimetric and differential
thermal analysis (TG-DTA), Inductance Coupling Plasma (ICP) and X-ray
photoelectron spectroscopy (XPS) measurement technolog...

Fast and facile fabrication of porous polymer particles via thiol–ene suspension photopolymerization
A fast and facile method of preparing porous polymer particles via thiol–ene suspension photopolymerization was studied. The porous particles were fabricated by adding the porogen to the click chemistry system. In this paper, the photopolymerization of dipentaerythritol hexakis (3-mercaptopropionate), pentaerythritol tetrakis (3-mercaptopropionate), 1,3,5-tri-2-propenyl-1,3,5-triazine...

Preparation and characterization of bovine serum albumin surface-imprinted thermosensitive magnetic polymer microsphere and its application for protein recognition
A novel bovine serum albumin surface-imprinted thermosensitive magnetic composite microsphere was successfully prepared by the surface grafting copolymerization method in the presence of temperature-sensitive monomer N-isopropylacrylamide (NIPAM), functional monomer methacrylic acid (MAA) and cross-linking agent N,N′-methylenebisacrylamide (MBA). The structure and component of the thermosensiti...

Scalable preparation of multiscale carbon nanotube/glass fiber reinforcements and their application in polymer composites
The introduction of carbon nanotubes (CNTs) into conventional fiber
to construct a hierarchical structure in polymer composites has attracted great
interest owing to their merits of performance improvement and multiple
functionalities. However, there is a challenge for realizing the scalable preparation
of the multi-scale CNT-glass fiber (CNT-GF) reinforcements in practical
application. In this wo...

[Macro. Chem. Phys.] Catalytic Precision Polymerization: Rare Earth Metal-Mediated Synthesis of Homopolymers, Block Copolymers, and Polymer Brushes
Recent studies have shown that rare earth metal-mediated group transfer polymerization
(REM-GTP) can be applied to a variety of polar monomers, besides the classic (meth)-
acrylates or (meth)acrylamides, giving access to new polymeric materials. This article
highlights progress in this new fi eld and gives a current overview of the initiation and
propagation of vinylphosphonates, the extension to ...

Spherical Polymer Brushes in Solvents of Variable Quality: An Experimental Insight by TEM Imaging
The spherical micelle and vesicle composed of [PW12O40](3-) and poly(styrene-b-4-vinylpyridinium methyl iodide) are regarded as a model system to study spherical polymer brushes (SPBs) in solvents of various quality. The pure repulsions occur for the brush chains in the chloroform solution and chloroform/methanol mixture with a methanol volume ratio of 9.1%, where the grafted polystyrene chains ...

Preparation of Polymer Microspheres with Reactive Epoxy Group and Amino Groups as Stabilizers for Gold Nanocolloids with Recoverable Catalysis
Narrow disperse poly(divinylbenzene-co-glycidyl
methacrylate) (P(DVB-co-GMA))
microspheres with reactive epoxy group were prepared by distillation
precipitation copolymerization of divinylbenzene (DVB) and glycidyl
methacrylate (GMA) with benzoyl peroxide (BPO) as initiator in neat
acetonitrile. The epoxy group was modified with ethylenediaminie (EDA) for
transferring to amino group, which was use...

Construction of Response Patterns for Metal Cations by Using a Fluorescent Conjugated Polymer Sensor Array from Parallel Combinatorial Synthesis
Pattern-based strategy is an emerging field of interest for effective sensing applications. Seven different conjugated polymers from combinatorial synthesis were combined into a sensor array, and seven metal cations were selected as representative analytes. The response patterns for each cation were constructed by collecting the individual fluorescence responses from seven...

GLASS TRANSITION BEHAVIOR OF THE SPIN-COATED THIN FILMS OF A HYDROPHILIC POLYMER ON THE SUPPORTED SUBSTRATES
Using ellipsometry, we found the glass transition temperature of the spin-coated polyacrylamide (PAL) thin films on the supported silicon (Si) substrates with an oxide layer decreases with decreasing the film thickness. But Tgs of the as-prepared thin films are much higher than that of the bulk sample. Such observations may be attributed to the combined result of the “surface effect” and...
