The application of carbon fiber-reinforced composites (CFRCs) is limited owing to the difficulty of chemically recycling carbon fibers (CFs). To address this problem, we cured tung oil-based triglycidyl ester (TOTGE) with menthane diamine (MDA) in order to obtain a chemically degradable bio-based vitrimer matrix. The obtained vitrimer matrix could undergo a dynamic transesterification reaction catalyzed by the tertiary amines generated from the curing reaction. The TOTGE−MDA vitrimer matrix shows excellent self-healing performance, physical reprocessing, and shape memory properties. Meanwhile, CFRCs based on the TOTGE−MDA vitrimer matrix also exhibited excellent reprocessing, self-adhesive, and shape memory properties. The CFRC underwent rapid chemical degradation with ethanolamine at 90 °C. The performance of the recycled CFs was similar to that of the virgin CFs. This work provides an effective solution to facilitate the sustainable development of CFRCs.

“…Thermally and chemically reversible dynamic covalent networks were obtained by crosslinking epoxidized soybean and linseed oils with 2,2-dithiodibenzoic acid, a disulfide-containing carboxylic diacid hardener that allows chemical recyclability and thermal reprocessing [ 95 ], and the work was complemented with a further investigation of many other vegetable sources as raw materials for the same purpose [ 96 ]. Vitrimers are a class of resins that can change their topology via a dynamic bond exchange, resulting in their self-healing and reprocessable molding [ 97 ]. Vegetable oil-based epoxy vitrimers with triple exchange crosslinkers of carboxylate ester bonds, disulfide bonds, and dioxaborolane were prepared and exhibited self-healing and recyclability properties, enabled by the dioxaborolane metathesis reaction of boronic ester, which is activated at room temperature with moderate humidity [ 98 ].…”

A progressively increasing concern about the environmental impacts of the whole polymer industry has boosted the design of less aggressive technologies that allow for the maximum use of carbon atoms, and reduced dependence on the fossil platform. Progresses related to the former approach are mostly based on the concept of the circular economy, which aims at a thorough use of raw materials, from production to disposal. The latter, however, has been considered a priority nowadays, as short-term biological processes can efficiently provide a myriad of chemicals for the polymer industry. Polymers from renewable resources are widely established in research and technology facilities from all over the world, and a broader consolidation of such materials is expected in a near future. Herein, an up-to-date overview of the most recent and relevant contributions dedicated to the production of monomers and polymers from biomass is presented. We provide some basic issues related to the preparation of polymers from renewable resources to discuss ongoing strategies that can be used to achieve original polymers and systems thereof.

The review article presents an analysis of the properties of epoxy and thermosetting resin composites containing eugenol derivatives. Moreover, eugenol properties were characterized using thermogravimeters (TGA) and Fourier-transform infrared spectroscopy (FTIR). The aim of this work was to determine the possibility of using eugenol derivatives in polymer composites based on thermoset resins, which can be used as eco-friendly high-performance materials. Eugenol has been successfully used in the production of epoxy composites as a component of coupling agents, epoxy monomers, flame retardants, curing agents, and modifiers. In addition, it reduced the negative impact of thermoset composites on the environment and, in some cases, enabled their biodegradation. Eugenol-based silane coupling agent improved the properties of natural filler epoxy composites. Moreover, eugenol flame retardant had a positive effect on the fire resistance of the epoxy resin. In turn, eugenol glycidyl ether (GE) was used as a diluent of epoxy ester resins during the vacuum infusion process of epoxy composites with the glass fiber. Eugenol-based epoxy resin was used to make composites with carbon fiber with enhanced thermomechanical properties. Likewise, resins such as bismaleimide resin, phthalonitrile resin, and palm oil-based resin have been used for the production of composites with eugenol derivatives.
