Selectively grafting polymer from the interior and/or exterior surfaces of bioreducible and temperature-responsive nanocapsules
A novel strategy is reported for selectively grafting polymer brushes from the interior and/or exterior surfaces of bioreducible and temperature-responsive nanocapsules. Poly(N-isopropylacrylamide-copoly(ethylene glycol) methacrylate) (P(NIPAM-co-PEGMA)) nanocapsules with hydroxyl groups at the interior surface, exterior surface or both surfaces were first prepared via seeded prec...

Probing Molecular Structures of Polymer/Metal Interfaces by Sum Frequency Generation Vibrational Spectroscopy
Sum frequency generation (SFG) vibrational spectroscopy has been applied to investigate the molecular structure of the buried poly(methyl methacrylate) (PMMA)/silver (Ag) interface. To elucidate such a structure, PMMA films with different thicknesses deposited on Ag substrates have been studied in the experiments. SFG signals collected from such PMMA films are interference res...

pH-responsive double hydrophilic protein-polymer hybrids and their self-assembly in aqueous solution
Double hydrophilic protein-polymer hybrids were
successfully prepared by Bgrafting-to^ method. Sodium polyacrylate (PANa) with an activated end group was prepared using acrylic acid as initial monomer by atom transfer radical polymerization (ATRP) in the water/DMF mixture at pH 7.8. Then, the activated end group of PANa directly covalently binds to the primary amino groups of the lysine of bovine ...

A Borinic Acid Polymer with Fluoride Ion- and Thermo-responsive Properties that are Tunable over a Wide Temperature Range
A new type of smart borinic acid polymer with luminescence and multiple stimuli-responsive properties is reported. In DMSO with small amounts of water, the homopolymer PBA shows a tunable upper critical solution temperature (UCST). As the amount of water increases from 0 to 2.5% (v/v), the UCST rises linearly from 20 degrees C to 100 degrees C (boiling point of water). Thus, the thermal responsive...

[Polym. Chem.] Ultrathin free-standing polymer membranes with chemically responsive luminescence via consecutive photopolymerizations
A facile and general method for the preparation of chemically responsive
polymer films is demonstrated. First, a crosslinked polymer precoating
layer is created via self-initiated photografting and
photopolymerization of ethylene glycol dimethacrylate on a
self-assembled monolayer of a 3-(trimethoxysilyl)propylamine modified
oxidized silicon wafer. The intact methacrylate function...

A facile fabrication of multifunctional knit polyester fabric based on chitosan and polyaniline polymer nanocomposite
Knit polyester fabric was successively modified and decorated with chitosan layer and polyaniline polymer nanocomposite layer in this paper. The fabric was firstly treated with chitosan to form a stable layer through the pad-dry-cure process, and then the polyaniline polymer nanocomposite layer was established on the outer layer by in situ chemical polymerization method using ammonium persulfate a...

【Chem Commun】A novel hydrophilic polymer-brush pattern for site-specific capture of blood cells from whole blood
A novel hydrophilic PAMPS–PAAm brush pattern is fabricated to selectively capture blood cells from whole blood. PAMPS brushes provide antifouling surfaces to resist protein and cell adhesion while PAAm brushes effectively entrap targeted proteins for site-specific and cell-type dependent capture of blood cells.

【Compos Sci Technol】Preparation, morphology, and mechanical properties of carbon nanotube anchored polymer nanofiber composite
Carbon nanotubes (CNTs) were anchored onto electrospun nanofibers under the assistance of ultrasonication. During ultrasonication, CNTs in the dispersion medium were driven to hit the nanofibers intensively and could be uniformly embedded onto nanofiber surface. The interaction between CNTs and dispersion medium played a vital role in determining CNT decoration. Good dispersion of CNTs in the disp...

【Polymer】A facile route for preparing stable co-continuous morphology of LLDPE/PA6 blends with low PA6 content
A facile method is employed to prepare a series of LLDPE/PA6 blends with co-continuous morphology with low PA6 content via reactive extrusion. In these blends, co-continuous morphology is obtained by introducing graft copolymers with both high and low molecular weight trunk chains to the interface simultaneously. Maleic anhydride functionalized polybutadine (PB-g-MAH, View the MathML source and ...
