Abstract: The invention discloses a composite nanometer fiber film formed by compositing chitosan, gelatin and shape memory polyurethane; the chitosan and gelatin are prepared by the weight ratio of (0.5-2):1; the total weight of the chitosan and gelatin and the weight of the shape memory polyurethane are prepared by the ratio of (0.2-2):1; the composite nanometer fiber film preparation method comprises the following steps: dissolve the chitosan, gelatin and shape memory polyurethane into a solvent so as to obtain a homogeneous solution; using a static spinning method to process the homogeneous solution so as to obtain the composite nanometer fiber film; carrying out proper after treatment for the composite nanometer fiber film. The composite nanometer fiber film is good in cell compatibility, wide spectrum antibiosis activity, haemostasis performance, permeability, mechanical strength, shape memory function, water vapor transmittance, heat stability and imbibition rate, and can be applied as biology medical dressing.
