Abstract

A reinforced oil-absorptive membrane material, includes: a tubular support () and an oil absorbing layer () provided on a surface of the tubular support (), wherein a plurality of holes are provided on the tubular support (); and the oil absorbing layer () is a piece of nonwoven fabric with a polymer layer provided thereon. The reinforced oil-absorptive membrane material has an excellent oil-absorbing and supportive performance, and is capable of being utilized continuously in a negative pressure suction manner and thus shows high oil absorption efficiency. A method for manufacturing the reinforced oil-absorptive membrane material including pre-treating the nonwoven fabrics by aqueous alkali, covering a membrane casting solution including a solvent, a graphene, polyvinylidene fluoride, pore-forming agent and inorganic particle, and then solidifying and extracting to obtain the oil-absorbing layer.
