Abstract
The overarching usage of ionic liquids (ILs) in reversible-deactivation radical polymerization (RDRP) techniques to overcome the challenges posed by hazardous solvents opens new avenues. Herein, a photoinduced RDRP (photoRDRP) catalyzed by magnetic nano zero valent iron (nZVI) in recyclable IL has been established, offering excellent temporal control during polymerization of methyl acrylate (MA) by merely switching the UVA radiation (λmax ≈ 352 nm) “ON” and “OFF”, providing remarkable control over Mn and Đs. The chain end fidelity was also established by synthesizing various well-defined diblock copolymers having allowable Đs values (≤1.18).
期刊介绍:
European Polymer Journal is dedicated to publishing work on fundamental and applied polymer chemistry and macromolecular materials. The journal covers all aspects of polymer synthesis, including polymerization mechanisms and chemical functional transformations, with a focus on novel polymers and the relationships between molecular structure and polymer properties. In addition, we welcome submissions on bio-based or renewable polymers, stimuli-responsive systems and polymer bio-hybrids. European Polymer Journal also publishes research on the biomedical application of polymers, including drug delivery and regenerative medicine. The main scope is covered but not limited to the following core research areas:
Polymer synthesis and functionalization
• Novel synthetic routes for polymerization, functional modification, controlled/living polymerization and precision polymers.
Stimuli-responsive polymers
• Including shape memory and self-healing polymers.
Supramolecular polymers and self-assembly
• Molecular recognition and higher order polymer structures.
Renewable and sustainable polymers
• Bio-based, biodegradable and anti-microbial polymers and polymeric bio-nanocomposites.
Polymers at interfaces and surfaces
• Chemistry and engineering of surfaces with biological relevance, including patterning, antifouling polymers and polymers for membrane applications.
Biomedical applications and nanomedicine
• Polymers for regenerative medicine, drug delivery molecular release and gene therapy
The scope of European Polymer Journal no longer includes Polymer Physics.
