Abstract :
Epoxy resins are among the most widely used thermosetting polymers in various industries and everyday applications due to their diverse properties. As the annual production and market demand for these resins continue to rise, it becomes increasingly important to address the challenges associated with their use and find effective solutions. Key challenges include the presence of toxic monomers and curing agents, high energy consumption during the curing process, and difficulties in recycling. For example, the toxicity of epoxy anti-corrosion resins can have detrimental effects on aquatic ecosystems. Additionally, the long curing times and elevated temperatures required for these resins lead to significant energy consumption. The thermosetting nature of epoxy resins also complicates recycling efforts, making it difficult to find environmentally friendly and cost-effective methods. To overcome these challenges, the use of bio-based monomers and curing agents is essential. Alternative curing methods, such as photocuring and oxidation-reduction reactions, can also be explored. Utilizing biocompatible activators and innovative energy sources can facilitate faster curing at lower temperatures. Furthermore, employing microorganisms for recycling can help minimize energy waste and reduce environmental impact. The synthesis of renewable resins, along with the development of epoxy resins featuring dynamic bonds, presents an optimal solution. This approach not only increases efficiency but also helps mitigate pollution risks to both the environment and human health, paving the way for a more sustainable future.
