Abstract

Over the past years, poly(lactic acid) or polylactide (PLA) is commonly researched as a possible replacement for traditional fossil-based polymers because of its compostability, biocompatibility, and high mechanical properties. PLA has a variety of applications in packaging, biomedical, and structural. However, PLA has limitations, such as high brittleness, low thermal stability, and a slow crystallization rate, which limits the wide range of applications. To overcome these limitations, the literature reports that blending PLA with other polymers, such as poly(ε-caprolactone) (PCL), is an economically viable approach. Although blending PLA with PCL is considered a feasible approach, the blend system still suffers from immiscibility, depending on the blend composition. This review aims to highlight recent developments from 2014 to date on the processing of PLA/PCL blends, including their composites, with a primary focus on morphological characteristics and mechanical and thermal properties, including their potential applications in various sectors.

聚乳酸/聚（ε-己内酯）共混物及其复合材料的形态特征、性能和应用--综述

过去几年来，聚乳酸或聚乳酸（PLA）因其可堆肥性、生物相容性和高机械性能而被广泛研究，成为传统化石基聚合物的可能替代品。聚乳酸在包装、生物医学和结构方面有多种应用。然而，聚乳酸也有其局限性，如脆性大、热稳定性低、结晶速度慢等，从而限制了其广泛的应用范围。为了克服这些局限性，文献报道聚乳酸与其他聚合物（如聚ε-己内酯（PCL））共混是一种经济可行的方法。尽管将聚乳酸与 PCL 混合被认为是一种可行的方法，但混合体系仍存在不溶性问题，具体取决于混合成分。本综述旨在重点介绍 2014 年至今在聚乳酸/ PCL 混合物（包括其复合材料）加工方面的最新进展，主要关注形态特征、机械和热性能，包括其在各个领域的潜在应用。
