Paragraph starter
The development of self-healing and reprocessable materials, as demonstrated by Pettazzoni et al. (2022) with their oleic acid-based elastomer, offers significant potential for sustainable design. Their work highlights how incorporating dynamic covalent bonds can lead to adhesives that not only exhibit strong substrate adhesion (e.g., to copper) but also possess inherent repair capabilities and can be recycled, thereby extending product lifespan and reducing material waste.
