According to the non-woven fabric, the carbon nanotubescan be uniformly dispersed in a styrene-maleic anhydride copolymer by surface functionalization, and mechanical strength of the non-woven fabric is enhanced; in the electrospinning process, the endsof the carbon nanotubes can be exposed from the surfaces of fibers, and the surfaces of the fibers are endowed with a heterostructure; the surface of each fiber can contain fluorine atoms by interaction between the fibers and a fluorocarbon surfactant, so that the oleophobic property of the fiber non-woven fabric can be maximized, and oil-water separation is facilitated..
