摘要

聚乳酸（PLA）基纳米复合材料作为一种多功能、可生物降解的材料正在兴起，为石油基塑料提供了可持续的替代品。本文综述了聚乳酸纳米复合材料的最新进展，重点是通过金属颗粒、碳基材料和陶瓷等纳米填料提高机械强度、热稳定性和可生物降解性。诸如原位聚合、熔体混合和静电纺丝等技术可以实现特定应用的改进。PLA的局限性，包括脆性和低阻隔性，是为了支持不同的应用：包装（例如，延长保质期），生物医药（例如，可降解植入物）和电子（例如，柔性器件）。尽管填料分散性和耐热性方面存在挑战，但持续的创新扩大了PLA在多个行业的潜力，为可持续的循环经济做出了贡献。

Polylactic acid (PLA)-based multifunctional and biodegradable nanocomposites and their applications

Polylactic acid (PLA)-based nanocomposites are emerging as multifunctional, biodegradable materials, offering sustainable alternatives to petroleum-based plastics. This review examines recent advancements in PLA nanocomposites, focusing on enhanced mechanical strength, thermal stability, and biodegradability achieved through nanofillers like metallic particles, carbon-based materials, and ceramics. Techniques such as in situ polymerization, melt mixing, and electrospinning enable application-specific improvements. PLA's limitations, including brittleness and low barrier properties, are addressed to support diverse applications: in packaging (e.g., extended shelf life), biomedicine (e.g., degradable implants), and electronics (e.g., flexible devices). Despite challenges with filler dispersion and thermal resistance, continued innovations expand PLA's potential across multiple industries, contributing to a sustainable, circular economy.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
