116.Multi-POSS cluster-wrapped polymers and their block copolymers with a PEO bottlebrush polymer: synthesis and aggregation
In this paper, we report an approach for synthesizing multi-cluster-wrapped polymers and their block copolymers with a bottlebrush polymer with controlled chain length and composition via living ringopening metathesis polymerization. To wrap more than one cluster on a polymer backbone, two to four polyhedral oligomeric silsesquioxane (POSS) clusters were firstly placed at the periphery of low-ge...

A Smart H2O2-Responsive Drug Delivery System Made by Halloysite Nanotubes and Carbohydrate Polymers
A novel chemical hydrogel was facilely achieved by coupling 1,4-phenylenebisdiboronic acid-modified halloysite nanotubes (HNTs-BO) with compressible starch. The modified HNTs and prepared hydrogel were characterized by solid-state nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscope (TEM). The li...

A well-defined amphiphilic polymer co-network from precise control of the end-functional groups of linear RAFT polymers
Linear polystyrene (PS) with well-defined molecular structure and accurate numbers of bromo groups on both ends were synthesized via multiple-step alternative RAFT polymerization of N-bromopropyl maleimide and bpinene monomers. The bromo end groups were transformed into the azido moieties via nucleophilic substitution. The reaction of as-synthesized linear PS having a named number of azide group...

9,10-Azaboraphenanthrene-containing small molecules and conjugated polymers: synthesis and their application in chemodosimeters for the ratiometric detection of fluoride ions
The introduction of main group elements into conjugated scaffolds is emerging as a key route to novel optoelectronic materials. Herein, an efficient and versatile way to synthesize polymerizable 9,10-azaboraphenanthrene (BNP)-containing monomers by aromaticity-driven ring expansion reactions between highly antiaromatic borafluorene and azides is reported, and the corresponding conjugated small m...

Effect of the polymer-substrate interactions on crystal nucleation of polymers grafted on a flat solid substrate as studied by molecular simulations
https://www.sciencedirect.com/science/article/pii/S0032386117306791
The crystallization behaviors of three types of polymer systems grafted on a flat solid substrate with different grafting densities were investigated by dynamic Monte Carlo simulations. For both of the systems with low and medium grafting densities, nucleation induction period becomes shorter with the increasing polymer-subst...

The effect of molecular weight of polymers grafted in two-dimensional filler on crystallization behaviors studied by dynamic Monte Carlo simulations
https://www.sciencedirect.com/science/article/pii/S0927025618305743
The crystallization behaviors of polymers can be changed by grafting them onto the surface of fillers. In this work, the effect of molecular weight of polymers grafted in two-dimensional filler on the isothermal crystallization behaviors was studied by the dynamic Monte Carlo simulation. The result shows that the grafted poly...

[ACS Sensor] Ultrafast and Efficient Detection of Formaldehyde in Aqueous Solutions Using Chitosan-based Fluorescent Polymers
Detection of a toxic formaldehyde (HCHO) pollutant in aqueous solutions is of significant importance, because HCHO is widely found in aquatic food because of illicit addition or improper storage. Many small-molecule-based fluorescent probes, which rely on HCHO-specific formaldehyde-amine condensation or the aza-Cope rearrangement reaction, have been developed in terms of facile operation and high ...

Facile synthesis of recyclable Zn(II)- metallosupramolecular polymers and the visual detection of tensile strength and glass transition temperature
We have successfully constructed a novel type of recyclable crosslinked Zn(II) metallosupramolecular coordination polymer, which possessed outstanding thermal stability and mechanical properties. More importantly, the tensile strength (RM) and glass transition temperature (Tg) of the resulting crosslinked films could be visually detected by taking advantage of the transparency decreasing effect ...

Recyclable Cu(II)-Coordination Crosslinked Poly(benzimidazolyl pyridine)s as High-Performance Polymers
Crosslinked high-performance polymers have many industrial applications, but are diffcult to recycle or rework. A novel class of recyclable crosslinking Cu(II)-metallo-supramolecular coordination polymers are successfully prepared, which possess outstanding thermal stability and mechanical property. More importantly, the Cu2+ coordination interactions can be further removed via external pyrophos...

【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...
