PLA/PBAT可降解地膜的制备技术和研究应用进展
Preparation Techniques and Research Applications of PLA/PBAT Biodegradable Films
摘要
Abstract
Traditional polyethylene(PE)agricultural mulching film is difficult to degrade,which is harmful to the environment and irreversible.Poly(lactic acid)(PLA)and poly(adipic acid-butylene terephthalate)(PBAT)can be blended to prepare high strength and high flexibility degradable composites,which can effectively improve environmental pollution when used as agricultural mulching film.In this paper,the preparation technology of PLA/PBAT mulching film was summarized,and the modification of materials by inorganic fillers and organic fillers was summarized.Finally,the application and development prospect of PLA/PBAT mulching film in current agricultural production were introduced.The research shows that the preparation technology of PLA/PBAT mulching film has entered a new development stage from excellent to excellent.The addition of organic fillers or inorganic fillers can reduce the cost of PLA/PBAT mulching film,improve the compatibility of materials,and enhance many key indexes such as mechanical properties,crystallization properties and barrier properties.In practical application,PLA/PBAT plastic film can promote crop growth and increase crop yield,but its uncontrollable degradation cycle affects its development.In the future,PLA/PBAT degradable plastic film with adjustable degradation cycle can be developed according to different crop growth factors.关键词
