Abstract: A hollow tubular oil absorbing material includes: a core formed by a spring, and an outer shell formed by a flat sponge wrapped at the spring; wherein the flat sponge is fixed at both ends of the spring; the flat sponge fully covers all the spring or is sealed at a first end; a connecting tube is connected at a second end of the spring for communicating with a vacuum pump; a graphene oxide layer is coated at the outer sponge. The graphene oxide layer on the flat sponge of hollow tubular oil absorbing material is formed by immersion and coating under negative pressure. Further the reduction of graphene oxide is performed with hydrazine hydrate steam and followed by washing and drying. Finally, a hollow tubular oil absorbing material with a spring core and an outer grapheme-coated sponge structure is obtained, which can be applied to continuous oil-water separation.
