Abstract:

Owing to its unique band structure, graphene possesses excellent thermal, mechanical, electrical and optical properties, which make it suitable for warious applications inchuding biological detection, energy storage, actuators, conductive composite membranes and so on. At first, the edvelopment of graphene-based composite fibers in recent years are introduced. Several methods for the preparation of graphene fibers including wet spinning, electrospinning, electrodeposition and chemical vapor diposition are leaborated in detail, and the performance of products obtained from each method are also compared. Then this review summauizes the relationship between the reaction conditions and the performance of graphene fibers, as well sa the applications of graphene fibers in the fields of wearable electronics and smart textiles. At last, prostpective on graphene fibers was also proposed, and may provide solutions for future research or applications of graphene fibers.

Key words: graphene, functional fiber, electrical conductivity, functional fiber
