The National University of defense technology successfully developed fully biodegradable polymer composites
the National University of defense technology recently held a scientific and technological achievements conference in Changsha, which is the first time that the university has released scientific research achievements to the society. At the same time, an exhibition of scientific and technological achievements was held, and the "fully biodegradable polymer composites" on display were favored
this technology is a national invention patent. It uses polycaprolactone with good biodegradability as the basic raw material. After chemical modification, it improves the temperature resistance of polycaprolactone (the temperature resistance is increased from 70 ℃ to 1 ℃. Look at the use of electro-hydraulic servo universal testing machine above 00 ℃), and improves the mechanical properties and molding processing properties of polycaprolactone, It has common sheet metal damage with other materials. In addition to the above situation, it also has excellent compatibility in the process of transportation. It can be mixed with various natural polymer materials to prepare polymer materials with complete biodegradability. Using the method of natural fiber reinforcement, composite materials and products with complete biodegradation can be prepared by strengthening modified polycaprolactone and other polymers with complete biodegradation. The biodegradable plastics are mainly used in production and life fields that cannot or are difficult to be reused and recycled, such as food packaging and containers (disposable tableware, packaging film, bags, etc.), industrial packaging applicable materials: rubber, plastic, film Adhesives, steel bars, glasses, touch screens, textiles, waterproof materials, wires and cables, ropes, metal wires, metal rods, metal plates and other photovoltaic materials, as well as materials in the clothing industry (such as packaging of electronic products), sanitary products (paper diapers, etc.), daily necessities, groceries (such as garbage bags, credit cards), and can also be used for agricultural and aquatic materials (agricultural film, fishing, etc.), civil construction materials and other environmental protection composite materials and products, At the same time, it can also be used in medical devices and other fields. The project conforms to the national industrial policy, with a large market and broad prospects. (gaohanwen)
