The invention belongs to the field of functionalized nanofibers and discloses a height stretchable and waterproof shape memory polymer fiber membrane, a preparation method and application thereof. Thefiber membrane is prepared by dissolving a high molecular polymer in a high molecular solution of an organic solvent A by an electrostatic spinning method to obtain a nanofiber membrane, mixing a fluorine-containing monomer with an oxygen-containing reactant, and carrying out water bath reaction at 70 -80 DEG C to obtain a fluorine-containing polymer, dissolving dopamine hydrochloride in a weak alkaline solution, placing the nanofiber in a dopamine solution, stirring to treat the surface of the nanofiber, cleaning the surface and then performing drying, dissolving the fluorine-containing polymer in an organic solvent B, and then spraying the organic solvent B on the nanofiber membrane subjected to surface treatment and performing drying. The fiber membrane comprises a shape memory polymerelectrospinning layer, a
