Polylactic acid (PLA)/silica composites as multifunctional high-performance materials have been extensively examined in the past few years by virtue of their outstanding properties relative to neat PLA. The fabrication methods, such as melt-mixing, sol-gel, and in situ polymerization, as well as the surface functionalization of silica, used to improve the dispersion of silica in the polymer matrix are outlined. The rheological, thermal, mechanical, and biodegradation properties of PLA/silica nanocomposites are highlighted. The potential applications arising from the addition of silica nanoparticles into the PLA matrix are also described. Finally, we believe that a better understanding of the role of silica additive with current improvement strategies in the dispersion of this additive in the polymer matrix is the key for successful utilization of PLA/silica nanocomposites and to maximize their fit with industrial applications needs.
聚乳酸（PLA）/二氧化硅复合材料作为多功能高性能材料，因其相对于纯聚乳酸具有突出性能，在过去几年中受到了广泛研究。文中概述了用于改善二氧化硅在聚合物基体中分散性的制备方法，如熔融共混、溶胶 - 凝胶和原位聚合，以及二氧化硅的表面功能化。重点介绍了PLA/二氧化硅纳米复合材料的流变学、热学、力学和生物降解性能。还描述了将二氧化硅纳米颗粒添加到PLA基体中所产生的潜在应用。最后，我们认为，更好地理解二氧化硅添加剂的作用以及当前改善该添加剂在聚合物基体中分散性的策略，是成功利用PLA/二氧化硅纳米复合材料并使其最大程度满足工业应用需求的关键。
