Scientists have invented tough, chemically recyclable polymers that maintain high performance under stress but can be precisely broken down and reused with no loss in quality. Their method uses a metal catalyst to trigger decomposition, potentially revolutionizing plastic recycling. =================================================================== Researchers at Osaka University have developed a new type of polymer that marries the toughness needed for demanding applications with the ability to be easily recycled into like-new material. Using a unique directing group that acts under specific conditions, this polymer withstands harsh environments yet breaks down effortlessly in the presence of a nickel catalyst. This innovation could make plastics...
