Photodegradable polar-functionalized polyethylenes

National Science Review, 2023
ABSTRACTThe degradation of plastics has attracted much attention from the global community. Polyethylenes (PEs), as the most abundant synthetic plastics, are most frequently studied. PE is non-degradable and non-polar because of the sole presence of the pure hydrocarbon components.
