Polymer materials are cheap, lightweight, and durable materials that can be easily made into various products and have been widely used. Primarily derived from nonrenewable resources like petroleum and natural gas, they are utilized in the production of disposable packaging and short-lived products, often discarded within a year. Obviously, our current use of polymer materials is unsustainable, causing a series of environmental problems and waste of resources during use and disposal. Therefore, the recycling and reuse of polymer materials is an important way to reduce these negative effects, and it has become one of the most active research and development areas in the polymer materials industry.
