Fully biodegradable polymer composite

Development: National University of Defense Technology

Characteristics: Polycaprolactone with good biodegradability is used as the basic raw material. After chemical modification, the temperature resistance of polycaprolactone is improved (temperature resistance is improved from 70°C to above 100°C), and the internal properties of polycaprolactone are improved. Ester's mechanical properties and molding process performance, and has excellent compatibility with other materials, can be used together with a variety of natural polymer materials. As a result, a polymer material having a completely biodegradable property can be manufactured. Using natural fiber-reinforced methods, composite materials and products with complete biodegradability can be produced by enhancing polymers such as modified polycaprolactones that have complete degradation properties.

Uses: The biodegradable material is mainly used in production and living areas where it is difficult or difficult to reuse and recycle, such as food packaging and containers (disposable tableware, packaging films, bags, etc.), industrial packaging materials (electronic products, etc. ), but also for medical devices and other fields.
