Recycling of Epoxy Resins with Degradable Structures or Dynamic Cross-Linking Networks: A Review

Industrial & Engineering Chemistry Research, Год журнала: 2024, Номер 63(12), С. 5005 - 5027

Опубликована: Март 19, 2024

Traditional epoxy resins (EPR), represented by bisphenol A type, have high chemical bond energy, low polarity, and stable properties. The topological structure after curing makes EPR impossible for convenient recycling through heating or dissolution like thermoplastics. This results in traditional having no advantage of efficient recycling, both molecular the combination morphology polymer chains. However, introducing degradable dynamically cross-linked structures into to modify their will bring good special responsiveness, with expectation achieve while maintaining original performance. paper reviews research progress cross-linkable such as ester, acetal, similar structures, Schiff bases, disulfide bonds, Diels–Alder addition structures. highlights impact these themselves on recycling. We discussed potential structures' findings small-molecule organic chemistry

Current State-of-the-Art and Perspectives in the Design and Application of Vitrimeric Systems

Molecules, Год журнала: 2025, Номер 30(3), С. 569 - 569

To fulfill the current circular economy concept, academic and industrial communities are devoting significant efforts to plastic materials’ end-of-life. Unlike thermoplastics, which easy recover re-valorize, recycling thermosets is still difficult challenging. Conversely, because of their network structure, thermosetting polymer systems exhibit peculiar features that make these materials preferable for several applications where high mechanical properties, chemical inertness, thermal stability, among others, demanded. In this view, vitrimers have quite recently attracted attention scientific community, as they can form dynamic covalent adaptive networks provide properties typical while keeping possibility being processed (and, therefore, mechanically recycled) beyond a certain temperature. This review aims an overview vitrimers, elucidating most recent advances posing some perspectives forthcoming years.

Biobased Networks from Lignin/Cellulose via Diels–Alder Click Chemistry

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(22), С. 13723 - 13734

Thermosets play a key role in modern plastic and coating industries. However, the cross-links responsible for their outstanding properties, such as improved tensile strength chemical thermal resistance, render them unable to undergo reprocessing or recycling. Herein, biobased thermosets were prepared from lignin cellulose via Diels–Alder (DA) click reaction, thereby providing fully polymer while envisioning properties of dynamic networks. Furan maleimide moieties attached soda cellulose. DA reactions then carried out using different combinations functionalized lignins bismaleimide, forming cross-linked network simultaneously enabling reversible control over thermally induced de-cross-linking re-cross-linking. In contrast, thermoreversibility was not achieved when associating both DA-based cross-links, even though mild reaction temperatures lower degrees cross-linking considered. Ultimately, study contributed widening use furan-maleimide chemistry preparation sustainable materials, insights into green versatile platform that may be considered future applications.
