Closed‐Loop Recycling of Vinylogous Urethane Vitrimers

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(36)

Published: July 13, 2023

Devising energy-efficient strategies for the depolymerization of plastics and recovery their structural components in high yield purity is key to a circular economy. Here, we report case study which demonstrate that vinylogous urethane (VU) vitrimers synthesized from bis-polyethylene glycol acetoacetates (aPEG) tris(2-aminoethyl)amine can be degraded by water at moderate temperature with almost quantitative (≈98 %) aPEG. The rate controlled temperature, amount water, molecular weight aPEG, composition starting material. These last two parameters also allow one tailor mechanical properties final materials, this was used access soft, tough, brittle vitrimers, respectively. straightforward preparation aPEG-based VU are interesting elements design polymer materials enhanced closed-loop recycling characteristics.

Hydrogels, as a class of three-dimensional (3D) polymer networks, are important candidates for drug delivery owing to their high porosity and hydrophilicity. Generally, clinical applications put forward various requirements systems (DDSs), such low toxic side effects, biocompatibility, targeting, controllable release, loading. In recent years, nanocellulose, including cellulose nanocrystals (CNCs) nanofibrils (CNFs), has emerged promising material hydrogel-based DDSs. This is due its surface area, abundant hydroxyl groups that can be easily chemically modified multifunctionalization, natural origin leading biocompatibility degradability, etc. review provides comprehensive overview the preparation methods hydrogels based on CNCs/CNFs use in systems, physical crosslinking chemical crosslinking. Additionally, carrier forms hydrogel particles, films, injectable hydrogels, sprayable discussed. Key parameters loading release efficiency well responses different stimuli also examined detail. Finally, view subdivision delivery, opportunities challenges nano were proposed from perspective application, potential research directions pointed out.
