[Polymer Chemistry] Mussel-inspired multifunctional supramolecular hydrogels with self-healing, shape memory and adhesive properties
A novel multifunctional
supramolecular hydrogel with self-healing, shape memory and adhesive properties
is successfully developed on the basis of dynamic phenylboronic acid (PBA)-catechol interactions. Thereversible nature of PBA-catechol bonds renders the hydrogel
outstanding self-healing and shape memory behaviors, and the mussel-inspired
catechol moieties generate fascinating adhesive propertie...

Highly alkynyl-functionization of cellulose nanocrystals and advanced nanocomposites thereof via click chemistry
A series of reactive GAP (glycidyl azide polymer)/PTPB (propargyl-terminated polybutadiene) nanocomposites reinforced by alkynylated cellulose nanocrystals (ACNC) were synthesized by Huisgen click chemistry. High-efficiency substitution (more than 80%) of the hydroxyl groups by alkynyl groups on the surface of CNC was realized through the esterification reaction between the alkyny...

(Liq. Cryst.) Photo-Responsive Polysiloxane-Based Azobenzene Liquid Crystalline Polymers Prepared by Thiol-Ene Click Chemistry
In this work, a novel polysiloxane-based azobenzene-containing liquid crystalline polymer (LCP) PMMS-A44V6 are designed and synthesized via a facile thiol-ene click chemistry method by grafting a side-on azobenzene mesogenic group A44V6 onto poly-[3-mercaptopropylmethylsiloxane] (PMMS) backbone. 1H NMR, 13C NMR, GPC, TGA, DSC, POM and WAXS are used to investigate the mesogenic properties and photo...

【Journal of Materials Chemistry B】High-efficiency immunoassay platform with controllable surface roughness and oriented antibody immobilization
Abstract:
High-efficiency immunoassay platforms with controlled surface roughness (single- and dual-scale structured surface) were prepared by combining a facile layer-by-layer particle deposition approach with oriented immobilization of antibodies through boronic acid moieties. The as-prepared surfaces showed significantly enhanced antibody loading capacity and antigen recognition, as proven...

Sustainable thermoplastic elastomers derived from plant oil and their “click-coupling” via TAD chemistry
We report the preparation of plant oil based triblock copolymers based on soybean oil monomers. The
monomers were polymerized via atom transfer radical polymerization with subsequent chain extension, resulting in poly(styrene-b-soybean oil acrylate-b-styrene) (PS-b-PSBA-b-PS) and poly(styreneb-soybean oil methacrylate-b-styrene) (PS-b-PSBMA-b-PS) triblock copolymers. These polymers...

【Journal of Materials Chemistry B】Infection-resistant styrenic thermoplastic elastomers that can switch from bactericidal capability to anti-adhesion
Abstract:
Styrenic thermoplastic elastomers (STPEs), particularly for poly(styrene-b-isobutylene-b-styrene) (SIBS),have aroused great interest in the indwelling and implant applications. However, the biomaterialassociated infection is a great challenge for these hydrophobic elastomers. Here, benzyl chloride (BnCl) groups are initially introduced into the SIBS backbone via Friedel–C...

[Analytical Chemistry] Flexible and Adhesive SERS Active Tape for Rapid Detection of Pesticide Residues in Fruits and Vegetables
The efficient extraction of targets from complex surfaces is vital for technological
applications ranging from environmental pollutant monitoring to analysis of explosive
traces and pesticide residues. In our present study, we proposed a
proof-of-concept surface enhance Raman scattering (SERS) active substrate
serving directly to the rapid extraction and detection of target molecules. The
novel su...

Synthesis and Characterization of Comb-like Methoxy Polyethylene Glycol-grafted Polyurethanes via ‘Click’ Chemistry
In this study, a series of comb-likemethoxy polyethylene glycol (MPEG)functionalized polyurethanes (PUs) (PU–g–MPEG)were successfully prepared via ‘click’ chemistry and polyaddition reaction. The copper catalyzed Huisgen 1,3-dipolar cycloaddition was firstly
carried out between 3,5-bis(hydroxymethyl)-1-propargyloxybenzene (PBM) and methoxy polyethylene glycol azide (MPEG–N3) to obta...

Synthesis of an Amphiphilic Brush Copolymer by a Highly Efficient “Grafting onto” Approach via CO2 Chemistry
A novel and robust route for the synthesis of a new amphiphilic brush copolymer, poly(glycidyl methacrylate)-graft-polyethylene glycol (PGMA- g -PEG), with high grafting densities of 97%–98% through a “grafting onto” method via carbon dioxide chemistry is reported. PGMAg-PEG can self-assemble and form stable spherical core–shell micelles in aqueous solution. Besides, the obtained P...

(Chem. Commun.) Near-Infrared-Responsive Gold Nanorod/Liquid Crystalline Elastomer Composites Prepared by Sequential Thiol-Click Chemistry
A
novel NIR-responsive GNR/LCE composite fiber material is prepared by a
three-step sequential thiol-click chemistry approach. Taking advantage of GNRs’
significant photo-thermal effect, GNR/LCE composite material with a very low Au
loading-level (0.09 wt%), under 808 nm NIR stimulus can achieve the N-to-I transition
and shrink dramatically in ambient environment.
