Grafting Antibiofilm Polymer Hydrogel film onto Catheter by SARA SI-ATRP
Abstract Catheters are widely used and play an important role in medicine. However, catheter-associated infection is prevalent even under stringent sterile conditions. Biofilms are formed when bacteria populate the surfaces of catheters. This makes the biofilm resistant to antibiotics. Hence, it is imperative for there to be an inherently antifouling and anti-bacterial
catheter to mitigate th...

Relaxation and Crystallization of Oriented Polymer Melts with Anisotropic Filler Networks
https://pubs.acs.org/doi/abs/10.1021/acs.jpcb.6b12569
The coexistence of nanofillers and shear flow can influence crystallization of polymer melts. However, the microscopic mechanism of the effect is not completely revealed yet. Thus, dynamic Monte Carlo simulations were used to study the effect of the filler networks formed by one-dimensional nanofillers on relaxation and crystallization of ...

Effect of interface on bulk polymer: control of glass transition temperature of rubber
In current paper, we demonstrated that molecular dynamics and glass transition of rubber can be controlled by constructing attractive interface between rubber matrix and fillers. Based on a combination of experiments and molecular simulations, it was revealed that interfacial segmental mobility was reduced and glass transition temperatures (Tgs) of epoxidized natural rubber (ENR) were significantl...

【03 Polymer Degradation and Stability】 Thermal and flammability properties of polypropylene/carbon black nanocomposites
Polypropylene/carbon black (PP/CB) nanocomposites were prepared by melt compounding to investigate the effect of nanofiller loadings on the thermal and flammability properties of PP. The obtained nanocomposites displayed not only dramatically enhanced thermal stability both under nitrogen and in air, but also improved flame retardancy to some extent. Moreover, the higher the loading level of CB,...

Ratiometric imaging of lysosomal hypochlorous acid enabled by FRET-based polymer dots
The development of an effective method for imaging of lysosomal hypochlorous acid (HClO) is of great significance to better understand the roles of HClO-related diseases. Herein, we report on the fabrication of fluorescence resonance energy transfer (FRET)-based fluorescent polymer dots (FPD) for the ratiometric imaging of lysosomal HClO in living cells via a simple co-precipitation method. This...

(Macromolecules)Polymer Micelles Stabilization on Demand through Reversible Photo-Cross-Linking
The stability of polymer micelles, which affects the stability of encapsulation of guest molecules, may be a crucial condition for some controlled delivery applications. It is possible that polymer micelles are disintegrated after being administrated in the body due to an extreme dilution to below the critical micelle concentration of the polymer.

Carbonization temperature controlled thermal conductivity of graphitic carbon nanoparticles and their polymer composites
Carbon materials as versatile fillers have drawn increasing attention in thermal conductive polymer composites, however, the thermal conductivity (TC) regulation of them remains challenging. Herein, the tunable lattice thermal conductivity is reported for glucose derived graphitic carbon nanoparticles (GCPs) and their polymer composites. Both the in-plane (La) and out-of-plane (Lc) coherence len...

59. [Polymer Chemistry] A tough, stretchable and extensively sticky hydrogel driven by milk protein
For
hydrogels, toughness and adhesiveness are contradictable.
However, the simultaneous requirement for both was
very urgent in some practical applications, such as robotics joints, wound
dressing and surgical bandage. Here in, milk casein as a protein model was
introduced into polyacrylamide (PAAm) hydrogel, which could achieve adequate
adhesiveness and mechanical strength. Surprisingly, casein-P...
