NOVELTY - Preparing pressure sensitive nano fiber film comprises dissolving polymer in organic solvent, mixing uniformly, adding thermal conductivity and pressure sensitive material, and electrospinning by electrostatic spinning technology to prepare pressure sensitive nanofiber film. USE - The nanofiber film is useful for wound dressing (claimed). ADVANTAGE - The nanofiber film has piezoelectric effect, can be attached on the whole layer wound of the mouse will not fall off (5 days), and can promote the healing of the wound of mouse wound.
