Research progress in graphene/polymer composite fibers and textiles

In view of the poor spinnability,high cost and difficult dispersion of high-purity graphene fibers,functional modification methods of graphene are summarized,and the research progress in polymer-based graphene fibers and fabrics is reviewed.Based on the analysis of the interaction between graphene and polymer matrix,the mechanism of graphene effect on the microstructure of polymer-based graphene fibers is also discussed,and the technical challenges and theoretical problems in the development of polymer-based graphene textiles are put forward.This review indicates that due to the high conductivity of graphene and flexibility of polymer matrix,the polymer-based graphene fibers have good flexibility and weavability,ensuring their good conductivity under the conditions of tension,torsion,impact,and so on.This is expected to accelerate the development process of flexible,wearable and smart textiles.It is pointed out that in face of the high cost of graphene,using controllable and predictable processing technology to solve the high dispersion of graphene,to achieve the high-efficiency under the low addition of graphene and to reduce the high cost,is an important research direction of polymer-based graphene textiles.
