Poly(lactic acid) (PLA) is considered the most promising biobased substitute for fossil-derived polymers due to its compostability, biocompatibility, renewability, and good thermomechanical properties. However, PLA suffers from several shortcomings, such as low heat distortion temperature, thermal resistance, and rate of crystallization, whereas some other specific properties, i.e., flame retardancy, anti-UV, antibacterial or barrier properties, antistatic to conductive electrical characteristics, etc., are required by different end-use sectors. The addition of different nanofillers represents an attractive way to develop and enhance the properties of neat PLA. Numerous nanofillers with different architectures and properties have been investigated, with satisfactory achievements, in the design of PLA nanocomposites. This review paper overviews the current advances in the synthetic routes of PLA nanocomposites, the imparted properties of each nano-additive, as well as the numerous applications of PLA nanocomposites in various industrial fields.
聚乳酸（PLA）因其可堆肥性、生物相容性、可再生性和良好的热机械性能，被认为是最有前途的生物基化石衍生聚合物替代品。然而，PLA存在一些缺点，如热变形温度低、耐热性和结晶速率低，而不同的终端应用领域需要一些其他特定性能，即阻燃性、抗紫外线、抗菌或阻隔性能、抗静电到导电特性等。添加不同的纳米填料是开发和增强纯PLA性能的一种有吸引力的方法。在PLA纳米复合材料的设计中，已经研究了许多具有不同结构和性能的纳米填料，并取得了令人满意的成果。本文综述了PLA纳米复合材料合成路线的当前进展、每种纳米添加剂赋予的性能，以及PLA纳米复合材料在各个工业领域的众多应用。
