【ACS Applied Materials & Interfaces】Temperature-responsive hierarchical polymer brushes switching from bactericidal to cell repellency
Abstract:
Unlike conventional poly(N-isopropylacrylamide) (PNIPAM)-based surfaces switching from bactericidal activity to bacterial repellency upon decreasing temperature, we developed a hierarchical polymer architecture, which could maintain bactericidal activities at room temperature while presenting bacterial repellency at physiological temperature. In this architecture, a thermoresponsive...

High efficiency organic solar cells based on amorphous electron-donating polymer and modified fullerene acceptor
The current manuscript examines the structure and property relationship of amorphous conjugated polymer based bulk heterojunction solar cells. Solvent vapor annealing (SVA) is used to optimize the morphology. It is seen that the structure order of the blended thin film does not change but phase separation becomes prominent. The space charge limited current and admittance spectroscopy reveals that ...

【Applied Surface Science】Enzyme-mimicking polymer brush-functionalized surface for combating biomaterial-associated infections
Abstract:
Biomaterial-associated infections critically compromise the functionality and performance of the medical devices, and pose a serious threat to human healthcare. Recently, natural DNase enzyme has been recognized as a potent material to prevent bacterial adhesion and biofilm formation. However, the vulnerability of DNase dramatically limits its long-term performance in antibacterial ...

[Langmuir] Supramolecular Host-Guest Interaction-Enhanced Adjustable Drug Release Based on β-Cyclodextrin-Functionalized Thermoresponsive Porous Polymer Films
Drug delivery systems based on stimuli-responsive porous polymer films (PPFs) have been extensively investigated because of their many advantages. However, the ability to adjust the drug release from PPFs is not always perfect, and at times, it cannot satisfy real-world requirements. In this paper, supramolecular host?guest interactions were harnessed to overcome the difficulties a...

6.【 Polymer】 Effect of Spreading Solvents on Langmuir Monolayers and Langmuir–Blodgett Films of PS-b-P2VP
Langmuir monolayers of polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) diblock copolymers (with the same PS block length and different P2VP block lengths) formed at the air/water interface were characterized with the Langmuir film balance technique. Nonselective and selective solvents were used to spread the samples on the water surface and the spreading solvents showed large effect on the s...

5.【 Polymer】Surface Phase Separations of PMMA/SAN Blends Investigated by Atomic Force Microscopy
The thin films of poly(methyl methacrylate) (PMMA), poly(styrene-co-acrylonitrile) (SAN) and their blends were prepared by means of spin-coating their corresponding solutions onto silicon wafers, followed by being annealed at different temperatures. The surface phase separations of PMMA/SAN blends were characterized by virtue of atomic force microscopy (AFM). By comparing the tapping mode AFM (T...

3.【Europ. Polym. J.】Monte Carlo Simulation of Miscibility of Polymer Blends with Repulsive Interactions: Effect of Chain Structure
The effects of the chain structure and the intramolecular interaction energy of an A/B copolymer on the miscibility of the binary blends of the copolymer and homopolymer C have been studied by means of a Monte Carlo simulation. In the system, the interactions between segments A, B and C are more repulsive than those between themselves. In order to study the effect of the chain structure of the A...

【ACS Applied Materials & Interfaces】Construction of hierarchical polymer brushes on upconversion nanoparticles via nir-light-initiated raft polymerization
Abstract:
Photoinduced reversible addition–fragmentation chain transfer (RAFT) polymerization generally adopts high-energy ultraviolet (UV) or blue light. In combination with photoredox catalyst, the excitation light wavelength was extended to the visible and even near-infrared (NIR) region for photoinduced electron transfer RAFT polymerization. In this report, we introduce for the first tim...
