▎ 摘　　要

NOVELTY - Preparing graphene aerogel fiber in low-temperature liquid comprises freezing and spinning the oxidised spinning graphene in the ethanol bath and forming the ethanol bath by mixing ethanol and liquid nitrogen. USE - The method is useful for preparing graphene aerogel fiber. ADVANTAGE - The fiber: has controllable aperture and orderly arranged pores; is simple; has without specific cooling device and does not need special refrigerating device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene aerogel fiber, which is prepared by above method.
