ABSTRACT Pressure‐sensitive adhesives (PSAs) are widely used in daily life, but their poor degradability poses significant challenges to sustainable development. To address this, we synthesized a polycarbonate, PPCB, using carbon dioxide and propylene oxide as raw materials, incorporating rigid benzene rings ester functional groups. PPCB exhibited T d,−5% , d,max that were 58.5% 30.7% higher than those of polypropylene carbonate (PPC), respectively. Its highest tensile strength was 55% PPC, while its elongation at break decreased from 421% 165%. The 180° peel reached 5.2 ± 0.56 N /cm, surpassing some commercial products such Duct‐tape. demonstrated high stable adhesion (~52 ) on various substrates. skin tissue 26.6 1.6 kPa, significantly commercially available fibrin glue. Rheological studies indicated maintained viscosity throughout the testing process, with lap shear close 4.56 MPa. Additionally, showed excellent degradability, water absorption rate weight loss. also good biocompatibility, cell viability greater 90%. has potential become novel degradable PSA, providing new solution for environmental sustainability.

Carbon dioxide (CO2) reduction to value-added chemicals for sustainable and clean energy is hindered by its considerable ionization potential (IP) negative adiabatic electron affinity (EA), which makes CO2 a chemically inert molecule, leading challenging unfavorable conversion under ambient conditions. To cope with this challenge, novel catalysts have been developed lower the activation reactions. However, low activity, selectivity, deactivation of limit their industrial applications.
