Studying Polymer Surfaces and Interfaces with Sum Frequency Generation Vibrational Spectroscopy
Usually a surface or an interface is well-defined with little diffusion from one side of the surface or interface to the other, with the length scale being on the order of one to several molecules. The molecular interactions on a surface or at an interface are thus dominated by short-range interactions. Various properties, such as wettability, reactivity, bi...

(Polymer) Magnetoresistive Polyaniline-Magnetite Nanocomposites with Negative Dielectrical Properties
Magnetic polyaniline (PANI) polymer nanocomposites (PNCs) reinforced with magnetite (Fe3O4) nanoparticles (NPs) have been successfully synthesized using a facile surface initiated polymerization (SIP) method. The chemical structures of the PANI/Fe3O4 PNCs are characterized by Fourier transform infrared (FT-IR) spectroscopy. The thermal stability of the PANI/Fe3O4 PNCs is performed ...

[Polym. Chem.] Polymer Brushes on Metal–Organic Frameworks by UV-Induced Photopolymerization
Metal–organic frameworks (MOFs) are extremely promising candidates for application in diverse fields. However, a limitation to the widespread use of MOFs is the absence of a facile and efficient chemical modification method which can greatly improve their poor processability and stability without altering the inherent outstanding chemical and physical properties. Herein, we report a universal pos...

[ Polymer] Electrically conductive thermoplastic polyurethane/polypropylene nanocomposites with selectively distributed graphene
The electrically conductive nanocomposites composing of different concentrations (0.05–1.5 wt%) of reduced graphene oxide (RGO) in the thermoplastic polyurethane/polypropylene (TPU/PP, 55/40) matrix with a fine co-continuous structure were fabricated by solution-flocculation and melt-mixing process using a micron twin-screw extruder. Both thermodynamic and kinetic theoretical analysis predicate...

013. Phase morphologies of binary polymer blends predicted by systematically coarse-grained models
In this work, the combined iterative Boltzmann inversion/conditional reversible work scheme is extended with a little modifications to derive the systematically coarse-grained (CG) potentials for simulating two typical atactic polymer blends composed of poly(methyl methacrylate) (PMMA) and poly(vinyl chloride) (PVC) or polystyrene (PS). Molecular dynamics simulations are extensively perform...

Temperature-responsive “tadpole-shaped”protein–polymer hybrids and their self-assembly behavior
The temperature-responsive poly (N, N-diethylacrylamide) (pDEAAm) with narrower molecular weight distribution was prepared by the atom transfer radical polymerization and characterized by 1HNMR and gel permeation chromatography.The temperature-responsive “tadpole-shaped” BSA–pDEAAm hybrids were fabricated via a free Cys-34
residue of bovine serum albumin (BSA) site specifically binding ...

Synthesis of a Novel Amphiphilic Polymer Containing Nucleobases in the Self-organized Nanospheres.
A simple strategy to achieve molecular recognition in water is to make the polymers self-organized into nanospheres which could incorporate the functional groups containing hydrogen bonding sites into hydrophobiclipophilic regions. A novel amphiphilic polymer, Poly(polyoxyethylene-600)-oxy-5-(6-(1-thymine)hexyl)) isophthaloyl (PPETHI), has been synthesized. The PPETHI polymer ...

A processable hybrid supramolecular polymer formed by base pair modified polyoxometalate clusters.
A new type of organic–inorganic hybrid supramolecular polymer has been prepared by using the base group modified polyoxometalate clusters as monomers, where the hydrogen bonds between the complementary base pairs act as the driving force.

Design of Multistimuli-Responsive Shape-Memory Polymer Materials by Reactive Extrusion
Shape-memory polymers (SMPs) are a class of stimuli-responsive materials that have attracted tremendous attention in various applications, especially in the medical field. While most SMPs are thermally actuated, relating to a change of thermal transition (e.g., melting temperature), SMPs that can be actuated upon exposure to light are emerging. Recently, there has b...

A novel fluorescent polymer brushes film as a device for ultrasensitive detection of TNT
In this work, we first report the application of fluorescent polymer brushes film as a device for ultrasensitive
and selective detection of TNT. As positively charged fluorescent molecules of quaternary ammonium
tetraphenylethylene derivatives (d-TPE) were self-assembled on the brushes of poly(acrylic acid) (PAA) by
coulomb forces, we obtained a novel fluorescent polymer brushes film with excellen...
