United KingdomResearchers at Virginia Tech have developed a new type of degradable polymer by rearranging molecular structures into ring shapes, creating materials that combine strength, toughness, flexibility, and effective oxygen barrier properties. These polymers show promise for food packaging applications, as they match the oxygen-blocking capabilities of polylactic acid (PLA), a common biodegradable plastic, while being tougher and more flexible. The study, led by Professor Rong Tong and Assistant Professor Yifan Cheng, involved altering polymer chain sequences to create 'gradient' polymers with improved mechanical properties. This innovation could lead to more sustainable and durable packaging solutions.
