Abstract

Two types of graphene oxide fibers are spun from high concentration aqueous dopes. Fibers extruded from large flake graphene oxide dope without drawing show unconventional 100% knot efficiency. Fibers spun from small sized graphene oxide dope with stable and continuous drawing yield in good intrinsic alignment with a record high tensile modulus of 47 GPa.

摘要

两种类型的氧化石墨烯纤维是由高浓度水基纺丝液纺制而成的。未经拉伸从小尺寸氧化石墨烯纺丝液中挤出的纤维表现出非传统的 100%结效率。从小尺寸氧化石墨烯纺丝液中稳定连续拉伸纺制的纤维具有良好的本征取向，拉伸模量高达 47GPa，创历史新高。
