Applications and Properties of Polymers

Emily Abbott from the American Chemical Society introduces a media briefing on sustainable wind turbine blades made from a new resin. Dr. John Dorgan discusses his research on renewable resins, focusing on PLA polymers. The briefing covers recycling, upcycling, and chemical modifications of the resin, highlighting its applications in various industries. Dr. Dorgan emphasizes molecular flexibility and future applications, including engineered stone products and lightweight materials for vehicles. The session concludes with potential future research directions.
