石油基材料的过度消耗及塑料垃圾的产生给周边环境和人类生活造成了不可逆转的伤害,大力发展可替代石油基材料的产品成为当今急需解决的问题。聚乳酸作为一种线性脂肪族热塑性塑料,因具有良好的机械性能及可加工性,成为目前开发最广泛的商业化聚合物之一。立构复合聚乳酸为研发具有优异物理化学性能且可降解的热塑性塑料提供了研究思路。介绍了近年来几种较为新颖的立构复合聚乳酸材料的制备方法,归纳了立构复合聚乳酸材料的结构与性能,并指出其未来的研究方向。
The excessive consumption of petroleum-based materials and the generation of plastic waste have caused irreversible damage to the surrounding environment and human life.It has become an urgent issue to develop products that can replace petroleum-based materials.Polylactic acid,as a linear aliphatic thermoplastic,has become one of the most widely developed commercial polymers due to its good mechanical properties and processability.Stereocomplex-polylactic acid provides a powerful way to develop degradable thermoplastics with excellent physical and chemical properties.In this paper,several novel preparation methods of stereocomplex-polylactic acid materials were introduced,the structures and properties of stereocomplex-polylactic acid materials were summarized,and the future research directions were discussed.
