In this research, we have developed a novel approach for the upcycling of polyethylene terephthalate (PET) waste, addressing the urgent need for sustainable material management. By employing glycolysis, we successfully converted PET into bis(2-hydroxyethyl) terephthalate (BHET) monomers, which served as the foundational building blocks for synthesizing polyurethane. We further engineered the polymer matrix to include disulfide bonds, which are pivotal in bestowing the material with self-healing capabilities, enabling it to repair damage at room temperature. Additionally, the incorporation of 5 wt% graphene oxide (GO) enhanced the material's electrical conductivity, making it suitable for wearable sensor applications. This combination not only contributes to the durability and functionality of the polyurethane but also aligns with the principles of a circular economy by facilitating the reuse and self-repair of polymeric materials.
