微多孔聚乳酸定向薄膜及其应用;MICRO-POROUS POLYLACTIC-ACID ORIENTED FILM AND USE THEREOF

摘要

本发明提供了一种微多孔聚乳酸定向薄膜，当薄膜处于薄膜中聚乳酸组分的玻璃化温度以下时，具有直径在10-1000nm范围内的表面孔，该等孔面积之和占所述薄膜总表面积的20%以上。本发明的优点在于可以制得具备热稳定性的密集、均匀的奈米级微孔的微多孔定向薄膜，且加工方法简单、高速，能够部分甚至完全生物降解。该微多孔定向薄膜可以在卫生护理、医疗、建筑、水处理、农业、电子产品、包装、装饰等领域应用。; and that the film is partly or even fully biodegradable. The micro-porous oriented film is applicable in the fields such as healthcare, medical applications, architecture, water treatment, agriculture, electronic devices, packaging and ornament.
