![]() ![]() Therefore, in the present work, oleic acid has been used as the starting material for the synthesis of a dynamic polymer. Ī further step forward in the preparation of more sustainable polymeric materials can be pursued by using bio- or waste-derived materials for the monomer synthesis. Moreover, aromatic disulfide metathesis has proven to be effective in mild conditions and could occur with mild or without external stimuli. The latter, in particular, has caught lot of attention, because of the wide availability of molecules containing aromatic S-S bonds suitable for polymer synthesis. įor this purpose, different types of dynamic covalent chemistry have been employed, including transesterification, transamidation, Diels-Alder/retro Diels-Alder system and aromatic disulfide metathesis. ![]() A solution, aimed to go beyond these limitations, has been found in the inclusion into the polymeric structure of dynamic covalent bonds which confer a self-healing property, high reprocessability and recyclability, resulting in an extended material lifetime. Moreover, new research studies have been focused on the development of new kinds of polymers capable of overcoming the most notable limits of “classic” polymeric materials, such as short lifetime and difficult recycling processes. Recently, studies about innovative and “greener” plastic materials have gained more and more interest than ever, mainly because of the highly negative impacts that “classic” oil-based and barely recyclable plastics have on the environment. Then, the application of the polymer as a solvent-free reusable adhesive for copper was investigated by lap joint shear tests and comparisons with the properties of an analogous material, devoid of the disulfide bonds, were conducted. ![]() Moreover, the polymer can strongly interact with copper surfaces through the formation of stable Cu-S bonds. In particular, oleic acid has been used as starting material to follow the founding principles of the circular economy system and, thanks to the aromatic disulfide component, which is the foundation of the material dynamic characteristics, the obtained polymer resulted as being reprocessable and self-healable. Consequently, the synthesis of a dynamic covalent chemistry-based polymer and its chemical, thermal, and mechanical characterizations are reported in the present research. This is due to the fact that polymers containing dynamic functions possess a structure that affords reprocessability, recyclability and peculiar self-healing properties inconceivable for “classic” polymer networks. In the last decade, the application of dynamic covalent chemistry in the field of polymeric materials has become the subject of an increasing number of studies, gaining applicative relevance. ![]()
