聚乳酸作为一种可降解的高分子受到人们的广泛关注,然而乳酸本身聚合成的材料,力学强度和可塑性等方面还需改进,采用材料复合的方法可以提高聚乳酸性能。本文综述了以聚乳酸为基体的复合材料的种类和性能,并对其发展做出了展望。 Polylactic acid, as a kind of biodegradable polymer, attracts the extensive attention of people. However, the material synthesized by lactic acid itself needs to be improved in terms of mechanical strength and plasticity. The use of composite materials can improve the performance of polylactic acid. In this paper, the types and properties of polylactic acid matrix composites are reviewed and their development prospects are also discussed.
