[Chem Mater] Tough Biomimetic Hydrogels with High Fatigue Resistance Based on Self-Assembled Conjugated Polymer Belt Mesh Interlaced with a Polyelectrolyte Network
Supertough biomimetic hydrogels have been fabricated through in situ synthesis and guided assembling of positively charged conjugated polymer belts by using a parent poly(2-acrylamido-2-methylpropanesulfonic acid)/poly-(acrylamide) double network (PAMPS/PAAm DN) gel template. The interpenetrating structures of the poly(3,4-ethylenedioxythiophene) (PEDOT) belt mesh and PAMPS/PAAm host network have ...

136. Strong enhancements of nucleation and spherulitic growth rates through amplified interfacial effects for immiscible linear polymer/comb-like copolymer double-layer films
Cellulose-graft-poly[poly(ethylene glycol) methyl ether acrylate] (Cell-g-PPEGA) and poly[poly(ethylene glycol) methyl ether acrylate] (PPEGA) comb-like copolymers were synthesized by electron transfer atom transfer radical polymerization (ARGET ATRP). PPEGA/PLA and Cell-g-PPEGA/PLA pairs are both immiscible as indicated by slightly decreasing glass transition temperatures of PLA in the blends mea...

【Polymer】Improving hemocompatibility of styrene-b-(ethylene-co-butylene)-b-styrene elastomer via N-vinyl pyrrolidone-assisted grafting of poly(ethylene glycol) methacrylate
Abstract:
In this work, in order to enhance the grafting degree, N-vinyl pyrrolidone (NVP) was used to assist the melt grafting of the macromonomer-poly(ethylene glycol) methyl ether methacrylate (PEGM)-which has good hemocompatible property, onto styrene-b-(ethylene-co-butylene)-b-styrene (SEBS) elastomer with free radical initiator. The grafting degree of PEGM with NVP assi...

Star-shaped polymer consisting of a porphyrin core and poly(L-lysine) dendron arms: synthesis, drug delivery and in vitro chemo/photodynamic therapy
A novel star-shaped polymer, porphyrin-poly(L-lysine) dendrons (PP-PLLD), is synthesized by
the click reaction between azido-modifi ed porphyrin and propargyl focal point poly(L-lysine)
dendrons. Its chemical structure is characterized by 1 H nuclear magnetic resonance, Fourier
transform infrared spectroscopy, and gel permeation chromatography (GPC) is analyses etc.
Due to its amphiphilic prop...

Room temperature spontaneous exfoliation of organo-clay in liquid polybutadiene: Effect of polymer end-groups and the alkyl tail number of organic modifier
Disorderly exfoliated telechelic liquid polybutadiene/organo-clay nanocomposite gel was, for the first time, successfully prepared at room temperature of 26 C by simply compounding of carboxyl-terminated polybutadiene (CTPB) with organo-clay containing surfactant modifier with two alkyl tails. The dispersion behavior of organo-clay in liquid polybutadiene/organo-clay nanocomposite gels were syste...

Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) as revealed by H-1 solid-state NMR spectroscopy
Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) (PAA) were systematically investigated using 1H CRAMPS solid-state NMR techniques in the temperature range from 25 to 110 °C. The 1H CRAMPS NMR methods are based on a recently developed continuous phase modulation technique for 1H-1H homonuclear dipolar decoupling. The 1H CRA...

Unusual rheological behavior of liquid polybutadiene rubber/clay nanocomposite gels: The role of polymer-clay interaction, clay exfoliation, and clay orientation and disorientation
The rheological properties of liquid polybutadiene rubber/organo-clay nanocomposite gels were investigated by rheological experiments, focusing on the effects of clay exfoliation and orientation-disorientation as well as polymer-clay interaction and temperature. Both irreversible and reversible viscosity transitions were observed in the temperature range from 26 to 136 °C in steady shear experime...

Receptor-Free Poly(phenylenevinylene) Fibrous Membranes for Cation Sensing: High Sensitivity and Good Selectivity Achieved by Choosing the Appropriate Polymer Matrix
Poly(phenylenevinylene)/polyimide (PPV/PI) and poly(phenylenevinylene)/ polymethylmethacrylate (PPV/PMMA) fibrous membranes without any deliberately introduced receptors were prepared as fluorescence sensing materials through electrospinning, followed by thermal treatment. Both of these membranes displayed higher sensitivity toward most cations compared to the corresponding spincoated films. PPV...
