The article "Application and Development of Smart Thermally Conductive Fiber Materials" by Zhan Sun, Huitao Yu, Yiyu Feng, and Wei Feng provides a comprehensive overview of the emerging materials and approaches in the development of smart thermally conductive fiber materials. These materials are characterized by their high thermal conductivity and smart response properties, making them suitable for various applications such as thermal management in electronic devices, personal temperature regulation, and aerospace applications. The authors categorize smart thermally conductive fiber materials into four main types: composite thermally conductive fibers filled with high thermal conductivity fillers, electrically heated thermally conductive fiber materials, thermally radiative thermally conductive fiber materials, and phase change thermally conductive fiber materials. Each category is discussed in detail, highlighting the unique properties and applications of these materials. Key advantages of smart thermally conductive fiber materials over traditional materials include their complex structure, greater plasticity and adaptability, superior functional characteristics, and broader application range. The article also discusses the challenges and opportunities faced by these materials, and presents future development prospects. The review covers recent advancements in the field, such as the use of carbon nanotubes, graphene, boron nitride, and transition metal carbide/nitride as fillers to enhance thermal conductivity. It also explores the integration of electrically conductive materials for Joule heating applications and the development of radiative cooling fibers for passive thermal management. Finally, the article discusses phase change materials (PCMs) and their integration into fiber materials to improve thermal comfort and efficiency. The use of coaxial electrostatic spinning, microencapsulation, and polymer backbone coating techniques to address leakage issues and enhance thermal properties is highlighted. Overall, the article provides valuable insights into the design and creation of innovative thermally conductive fiber materials, offering new perspectives and strategies for their future development.The article "Application and Development of Smart Thermally Conductive Fiber Materials" by Zhan Sun, Huitao Yu, Yiyu Feng, and Wei Feng provides a comprehensive overview of the emerging materials and approaches in the development of smart thermally conductive fiber materials.
