A hollow tubular oil suction material and a preparation method therefor. The core of the hollow tubular oil suction material is a spring (2), the outer side of the spring is wrapped with a sheet-shaped sponge (4), and the sponge (4) is fixed at two ends of the spring. At one end (31) of the spring, the top end of the spring is completely wrapped by the sponge (4), or the connection part of the top end of the spring and the sponge (4) is fixed and sealed; the other end (32) of the spring is fixedly connected to a connecting tube (1) used for connecting a vacuum pump; and the outer side of the sponge (4) is coated with a graphene oxide layer. The graphene oxide layer is formed by immersion of the sponge in a graphene oxide dispersion liquid, negative pressure pumping filtration, hydrazine hydrate steam reduction, flushing and vacuum drying. The preparation method is simple to operate, the hollow tubular oil suction material prepared by the method has low cost, continuous adsorption of oil products is achieved, and the oil-water separation efficiency is improved. |
