A review of the properties and applications of polyoxymethylene-based nanocomposites

Polyoxymethylene (POM), a widely used engineering plastic, is a highly crystalline thermoplastic polymer known for its mechanical strength, fatigue resistance, and chemical stability. POM is increasingly used as a substitute for metal in various applications, making it essential to continuously enhance its performance. Many researchers have investigated the modification of POM and proposed various methods for preparing POM composites, particularly emphasizing the use of nanomaterials as reinforcing agents. This review systematically summarizes the mechanical, thermal, crystallization, and tribological properties of POM and its nanocomposites (e.g., Nano-SiO 2 , Nano-Al 2 O 3 , Nano-ZnO, Carbon Nanotube, POSS, Hydroxyapatite, Nano-MoS 2 , MMT). Additionally, it focuses significantly on examining their application prospects, aiming to offer more optimal solutions for the utilization of POM. It is anticipated that this review will establish a robust theoretical foundation for future research in the field of POM and its nanocomposites and will also facilitate the effective deployment of POM-based materials across a broader range of critical fields.
