Flexible photocatalytic materials: From substrate engineering to multi‐field synergistic enhancement

FlexMat, EarlyView.
This review examines flexible photocatalytic systems, covering substrate evolution from polymers to biomass, fabrication methods like electrospinning, and key mechanical and optoelectrochemical metrics under deformation. Enhancement strategies are critically discussed, followed by applications in energy conversion, environmental remediation, and ...

Chain‐End Grafting of RAFT Polyelectrolyte Macroligands to Stabilize Near‐Infrared‐Emitting Gold Nanoclusters

Macromolecular Rapid Communications, EarlyView.
Surface‐functionalized gold nanoclusters (AuNCs) are synthesized in situ by chain‐end grafting of RAFT polyelectrolytes at room temperature directly in water. It leads to highly stable polymer‐AuNCs nanohybrids emitting near‐infrared photoluminescence with µs lifetimes. ABSTRACT With their photoluminescence properties, gold nanoclusters (AuNCs, d<2 nm)

Weighting of silk by graft copolymerization technique

, 2002
171-178Wild silk yarns and fabrics have been graft copolymerized with two monomers, namely methyl methacrylate (MMA) and methacrylic acid (MAA), using potassium peroxidisulphate and cerric ammonium sulphate to minimize homopolymer formation. The optimum

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Adhesion of Hydrogels to Fluoropolymers by Electrophoretic Fluoropolymer Coating

Macromolecular Rapid Communications, EarlyView.
Both fluoropolymers and hydrogels are generally regarded as difficult‐to‐bond materials; however, adhesion between them was achieved by coating the hydrogel with a fluorinated copolymer. ABSTRACT Although hydrogels are widely used in bio‐integrated devices and soft systems, their robust adhesion to polymers with low surface energies remains a ...

Synthesis and characterization of membranes obtained by graft copolymerization of 2-hydroxyethyl methacrylate and acrylic acid onto chitosan

, 2006
Chitosan based membranes to be applied on wound healing as topical drug delivery systems were developed by graft copolymerization of acrylic acid (AA) and 2-hydroxyethyl methacrylate (HEMA) onto chitosan using cerium ammonium nitrate as chemical ...

Modular Polymers With Tuneable Charge and Amphiphilicity for Effective Antimicrobial Photodynamic Therapy

Macromolecular Rapid Communications, EarlyView.
A modular dual‐strategy platform combining free radical copolymerisation and post‐polymerisation modification yields a library of ruthenium‐functionalised polymers for antimicrobial photodynamic therapy. Tuneable composition and net charge govern activity against multidrug‐resistant Pseudomonas aeruginosa biofilms and Staphylococcus aureus under ...

Preparation of Silicone-modified Waterborne Polyurethanes and their Dynamic Amphiphobicity

Pige Kexue Yu Gongcheng
Using the graft copolymerization method, two types of terminally hydroxy-functionalized silicone oils (Silok-8822F2 and Silok–8866) were introduced into polyurethane (PU) chains to prepare two series of silicon-modified waterborne polyurethanes (PU1 and ...
