The study introduces a novel series of poly(butylene citramalate-co-butylene succinate) (PBCS) copolymers, which are bio-based, degradable, and recyclable, offering a sustainable solution for plastic management. These polymers exhibit high toughness, recyclability, and degradability, with a remarkable 760% elongation at break. PBCS is designed to support a circular economy by enabling closed-loop cycles and reducing fossil-fuel dependency. It demonstrates excellent biocompatibility and wound healing efficacy, achieving complete skin and hair follicle regeneration in 7 days. This innovation positions PBCS as a transformative material for applications in biomedicine, electronics, and robotics, addressing critical sustainability and performance challenges.
