【ACS Applied Materials & Interfaces】Water-insoluble polymeric guanidine derivative and application in the preparation of antibacterial coating of catheter
Abstract:
Antibacterial coatings have been considered as an effective method for preventing the implant-associated infections caused by the bacterial colonization. In this study, we report a water-insoluble polyelectrolyte–surfactant complex, poly(hexamethylene biguanide) hydrochloride–sodium stearate (PHMB–SS) that can be facilely coated onto the surfaces of biomedical catheter and ...

【Polymer Chemistry】A pH and redox dual responsive homopolypeptide: synthesis, characterization, and application in "smart" single-walled carbon nanotube dispersion
Abstract:
A homopolypeptide, namely poly(S-(2-carboxylethyl)-L-cysteine) (PCELC), with pH and redox dual responsiveness was prepared by ring-opening polymerization of S-(2-(methoxycarbonyl)ethyl)-L-cysteine based N-carboxyanhydride (MCELC-NCA) and subsequent hydrolysis. The pH-induced solution phase transition of PCELC was at pH = ～4.50 as revealed by DLS and UV-vis spectroscopy. The th...

【Carbohydrate Polymers-2018年冬季】Synthesis of chitosan-based micelles for pH responsive drug release and antibacterial application
The over- and inefficient release of antibiotics from common delivery systems causes the development of drug-resistant bacteria. In the present work, methoxy poly(ethylene glycol)-poly(ε-caprolactone)-chitosan/montmorillonite (MPC/MMT) hybrid multilayer films were constructed for bacterial infections and pH-dependent release of the hydrophobic drug triclosan (TCA). The thickness of the (MP...

【62 Macromolecular Chemistry and Physics】 Main-chain polyimidazolium polymers by one-pot synthesis and application as nitrogen-doped carbon precursors
This paper reports on the one‐pot synthesis of main‐chain imidazolium‐containing polymers, some of which show unusually high thermal stability. The imidazolium polymers are obtained by modified Debus–Radziszewski reactions for the chain build‐up from simple organic compounds, here pyruvaldehyde, formaldehyde, acetic acid, and a variety of diamines. The reactions are performed in aqueous media...

【27 RSC Advances】 Synthesis and characterization of a novel organophosphorus oligomer and its application in epoxy resin
A novel organophosphorus, poly(4,4-dihydroxy-1-methyl-ethyl diphenol-o-bicyclic pentaerythritol phosphatephosphate) (PCPBO), was synthesized and characterized by FTIR, 1H NMR and 31P NMR. The flame retardancy and thermal stability of epoxy resin with different PCPBO loadings were investigated using the limited oxygen index (LOI), vertical burning test, cone calorimeter test and thermogravimetric a...

【11 Polymers for Advanced Technologies】 Synthesis and characterization of a novel organophosphorus flame retardant and its application in polypropylene
A novel organophosphorus containing spiro and caged bicyclic phosphate, 3,9‐Bis‐(1‐oxo‐2,6,7‐trioxa‐1‐phospha‐bicyclo[2.2.2]oct‐4‐ylmethoxy)‐2,4,8,10‐tetraoxa‐3,9‐diphospha‐spiro[5.5]undecane 3, 9‐dioxide (SBCPO), was synthesized and characterized by Fourier transform infrared (FTIR), hydrogen‐1 nuclear magnetic resonance (NMR) and phosphorus‐31 NMR. The flame retardancy of polyp...

Magnetic microcapsules with inner asymmetric structure: Controlled preparation, mechanism, and application to drug release.
Magnetic microcapsules with inner asymmetric structure are prepared by miniemulsion polymerization of styrene in presence of oleic acid-modified Fe3O4 as magnetic nanoparticles and n-heptane (HP) as core. The resultant microcapsules with novel structure exhibit magnetic anisotropy and cavity anisotropy. The formation mechanism of the microcapsule is illustrated in detail. The obtained results show...

Red-blood-cell-like BSA/Zn3(PO4)2 hybrid particles: Preparation and application to adsorption of heavy metal ions.
A novel kind of red-blood-cell-like bovine serum albumin (BSA)/Zn3(PO4)2 hybrid particle is prepared at room temperature by a facile and rapid one-step method based on coordination between BSA and zinc ion. The morphology of the monodisperse hybrid particle shows oblate spheroidal type with a one sided single hole on the surface. The hybrid particle is constructed with BSA/Zn3(PO4)2 nanoplates of ...

017. Multiscale modeling of glass transition in polymeric films: Application to stereoregular poly(methyl methacrylate)s
The multiscale modeling scheme has been extended to derive the coarse-grained potentials for simulating glass transition temperatures (Tg) of the bulks and the freely-standing films of two stereoregular poly (methyl methacrylate) (PMMA) configurations. The extensive molecular dynamics simulations reasonably reproduce the volumetric properties. Furthermore, the “dynamical Tg” sensibly exhibits ...
