Abstract
En 中文
This review systematically summarizes the synthesis mechanisms of polyamide 6 (PA6) via anionic ring-opening polymerization (AROP), with a focus on its advantages over hydrolytic and cationic polymerization routes, and key factors affecting the polymerization efficiency and material properties—including initiator selection, catalyst concentration, polymerization temperature, moisture content, and thermal oxidation—are critically analyzed. Furthermore, the review explores three reinforcement strategies for anionic polymerized PA6 (APA6) composites: organic polymer blending (e.g., in-situ copolymerization and graft modification), inorganic filler incorporation (e.g., TiO₂, MWCNTs), and fiber reinforcement (e.g., glass/carbon fibers). By integrating preparation process, APA6 composites exhibit superior mechanical strength, dimensional stability, and process flexibility, demonstrating potential in automotive, electronics, and sustainable material applications. Besides, this review show that challenges such as side reactions and water interference are discussed, and future directions for optimizing polymerization control and environmental adaptability are proposed. This work will provides a comprehensive theoretical foundation for advancing high-performance APA6 composites in industrial manufacturing.
