Abstract

The effect of coagulation time, the number of coagulation bath and ingredients on the properties of continuous graphene oxide fibre has been analyzed. It is observed that the number of coagulation baths and coagulation time affect the fibre morphology, electrical conductivity, and tenacity of fibre. Also, addition of the ingredient (ethylenediamine) results in lower strength and highest fibre count together with darker, curly, and rough fibre structure. It can be suggested that among all the samples, the sample with 1 coagulation bath and 2 min coagulation time can be preferred if electrical conductivity is more important than fibre tenacity. However, if fibre tenacity is the issue, preference of the sample with 3 coagulation baths and 2 min coagulation time will be more convenient.
