Continuous graphene oxide fiber and its applications

A liquid crystal form of graphene oxide is widely used for manufacturing graphene oxide fibers, films, and aerogels. The method of wet spinning (coagulation) of graphene oxide dispersion is a lowcost and available technique with high productivity, which is used to produce continuous graphene oxide fibers since last decade. Chemical and thermal reduction processes are also applied to reduce the graphene oxide fiber in order to improve properties such as electrical conductivity. Graphene oxide fibers have diverse applications such as multifunctional textiles, wearable electronics and fuel cells, batteries, sensors, and filters. The curent chapter focuses on continuous graphene oxide fiber, reduced graphene oxide fiber, composite graphene oxide fiber, their production, and applications.
