Research progress on liquid metal-based fiber composites application
Liquid metal(LM),a functional material with both electrical conductivity and fluidity,has gained widespread attention due to its excellent conductivity and deformation capabilities.Fiber materials,as commonly used flexible substrate,have shown broad application potential in many fields because of their excellent stretchability,breathability and weavability.In order to solve the problems of poor flexibility with electronic components and difficulty in meeting wearable and intelligent requirements,LM-based fiber composite materials,a combination of the matrix and conductive materials with the advantages of stretchable deformation and flexibility of fiber materials and the high conductivity and room temperature fluidity of LM,have been widely used in fields such as human motion monitoring and energy storage.In this review,the control strategies of LM-based fiber composite materials in terms of chemical stability,electrical and thermal properties were introduced.The research progress on application of LM-based fiber composite materials in flexible sensing,electromagnetic shielding,energy harvesting and storage was mainly described.Finally,some suggestions on the performance improvement of LM-based fiber composite materials and existing problems in the current research were put forward,and the future development directions was prospected.
