Research on modification strategies of bio-based polyamide 56

Abstract Bio-based polyamide 56 (PA56), as an emerging green and environmentally friendly material, has garnered significant attention across various industries, including textiles, automotive, and electronics, due to its excellent mechanical properties, thermal resistance, and renewability. Despite these advantages, polyamide 56 faces challenges related to processability, impact resistance, flame retardancy, and other functional properties. To expand its application scope and enhance the added value of polyamide 56 products, improving its performance through various modification techniques has become a focal point of research. This paper provides a comprehensive review of recent advances in modification strategies for polyamide 56, including reinforcement, flame retardancy, toughening, and antibacterial treatments. Additionally, this paper discusses the future application prospects of polyamide 56 and offers valuable insights to guide ongoing research in this field.
