Photocontrolled RAFT polymerization: past, present, and future

Chemical Society Reviews, Год журнала: 2023, Номер 52(9), С. 3035 - 3097

Опубликована: Янв. 1, 2023

In this review, we provide a brief history, progress, and applications, discuss the remaining challenges of photocontrolled reversible addition-fragmentation chain transfer (RAFT) polymerization (i.e., photoinduced electron/energy transfer-RAFT (PET-RAFT), photoiniferter, photomediated cationic RAFT polymerization). Among these, visible-light-driven has attracted particular attention in recent years due to its benefits, including low energy consumption safe reaction procedure. Moreover, incorporation visible-light photocatalysis conferred attractive features, such as spatiotemporal control oxygen tolerance; however, clear understanding mechanism not been completely provided. We also present research efforts elucidate mechanisms with aid quantum chemical calculations combined experimental evidence. This review offers an insight into better design systems for desired applications helps realize full potential both academic- industrial-scale applications.

Macromolecular Rapid Communications, Год журнала: 2021, Номер 43(1)

Опубликована: Ноя. 9, 2021

Light-mediated polymerization techniques offer distinct advantages over reactions fueled by thermal energy, such as high spatial and temporal control well the possibility to work under mild reaction conditions. Reversible addition-fragmentation chain-transfer (RAFT) is a highly versatile radical method that can be utilized variety of monomers produce vast number complex macromolecular structures. The use light drive RAFT-polymerization possible via multiple routes. Besides photo-initiators, or photo-catalysts, direct activation chain transfer agent controlling RAFT process in photo-iniferter (PI) an elegant way initiate reactions. Within this review, PI-RAFT its conventional are discussed detail.

A Photoinduced Dual‐Wavelength Approach for 3D Printing and Self‐Healing of Thermosetting Materials

Angewandte Chemie International Edition, Год журнала: 2021, Номер 61(11)

Опубликована: Дек. 3, 2021

Vat photopolymerization-based 3D printing techniques have been widely used to produce high-resolution thermosetting materials. However, the lack of repairability these thermosets leads production waste. In this study, reversible addition fragmentation chain transfer (RAFT) agents are incorporated into resin formulations allow visible light (405 nm) mediated materials with self-healing capabilities. The process is based on reactivation RAFT agent embedded in under UV (365 nm), which enables reformation polymeric network. can be performed at room temperature without prior deoxygenation. impact type and concentration polymer network healing efficiency explored. Resins containing enable properties, broadening scope future applications for various fields.

Materials Design of Highly Branched Bottlebrush Polymers at the Intersection of Modeling, Synthesis, Processing, and Characterization

Chemistry of Materials, Год журнала: 2022, Номер 34(5), С. 1990 - 2024

Опубликована: Фев. 23, 2022

Highly branched "bottlebrush" polymers are a class of macromolecules characterized by side chains that densely grafted from backbone is typically linear. Their unique and often-desirable properties stem steric repulsion between chains, which stiffens the molecular contour increases interchain spacing. There has been renaissance in both our fundamental understanding, practical synthesis, application these materials, due to synergistic advances all branches polymer science. In this perspective, we outline how wide variety new functional bottlebrush materials have emerged convergence insights entire design process; integration characterization, processing, modeling demonstrated promise as versatile platform for engineering. We discuss may be further developed exhibit novel material out equilibrium put into practice next generation synthetic, analytical, computational tools chemistry.
