摘要
纤维素和淀粉均为自然界中储量较丰富的天然高分子聚合物,微晶纤维素可作为增强相添加到热塑性淀粉基材制备塑料薄膜,因其具有良好的生物相容性、可生物降解特性而广泛应用在包装材料领域。文章简述了热塑性淀粉和微晶纤维素的特点,以及热塑性淀粉/微晶纤维素的制备机理。分析热塑性淀粉/微晶纤维素颗粒中常见两种增塑剂,对比热塑性淀粉/微晶纤维素塑料薄膜的四种制备工艺的特点,归纳不同类型热塑性淀粉/微晶纤维素塑料薄膜的研究进展,为研发绿色包装材料提供参考。
Cellulose and starch are natural polymers with abundant reserves in nature.Microcrystalline cellulose can be added to thermoplastic starch as a reinforcing phase to prepare plastic films.It is widely used in the field of packaging materials because of its good biocompatibility and biodegradability.The characteristics of thermoplastic starch and microcrystalline cellulose,and the preparation mechanism of thermoplastic starch/microcrystalline cellulose are briefly described.Two common plasticizers in thermoplastic starch/microcrystalline cellulose granules are analyzed.The characteristics of four preparation processes of thermoplastic starch/microcrystalline cellulose plastic films are compared,and the research progress of different types of thermoplastic starch/microcrystalline cellulose plastic films is summarized.The research provides a reference for the development of green packaging materials.
