In recent years, with the development of science and technology, degradable materials related to carbon dioxide copolymers are rapidly developed, so that the problem of white pollution can be fundamentally solved, and the sustainable development of green is promoted. However, the popularization and application of the degradable material prepared by the carbon dioxide copolymer are limited by factors such as non-ideal thermal and mechanical properties.
The patent CN202011020665.0 provides a functional degradable material with controllable degradation period and a preparation method thereof, and the functional degradable material with different degradation periods is prepared by interaction among polybutylene terephthalate, carbon dioxide-based copolymer, polybutylene succinate, auxiliary agent and the like, and can be suitable for different degradation periods. But its application is limited due to poor light stabilizer properties.
The patent CN201811563967.5 provides a stretch-proof degradable barrier plastic packaging film and a preparation method thereof, wherein carbon dioxide copolymer and maleic anhydride are used as raw materials, and substances such as monodisperse silica microspheres and the like are added in an auxiliary manner, so that not only is the mechanical property improved, but also the thermal stability of an intermediate barrier layer is improved. However, the preparation is complex, the production cost is high, and the requirements of customers cannot be fully met.
