摘要
One‐step continuous wet‐spinning of coaxial electroactive fibres of chitosan/graphene oxide (Chit/GO) via a facile method is introduced for the first time, eliminating the need for post‐treatment processes. Spinnability of coaxial fibres as well as their characterization for several properties is investigated. L‐ascorbic acid was found to reduce graphene oxide under mild conditions to create conductivity in the final fibre. As‐prepared fibres were found to be cytocompatible with good electrical conductivity and mechanical properties. SEM images from the cross‐section of Chit/GO fibres showed an irregular shaped multifilament GO fibre covered with a cylinder‐shaped sheath of chitosan. Coaxial fibres had an ultimate tensile stress and elastic modulus that increased 8 500% and 3 350%, respectively compared to the graphene oxide fibres alone.
