The invention discloses a reinforced tubular porous composite film, as well as a preparation method and an application thereof. The composite film consists of a tubular porous body, a first polymer material film and a second polymer material film. The composite film is obtained by coating the first polymer material film and the second polymer material film on the tubular porous body. The reinforced tubular porous composite film has the advantages of no surface defect, high water permeability, high tensile strength, wide selection range of the tubular porous body and easy production. |
