This article first reports the preparation of superconducting FeSe films on fluorophlogopite-mica (F-mica) substrates by the pulsed laser deposition technique. The quality of films is significantly improved by optimizing the deposition conditions, such as substrate temperature and laser energy. Through mechanical exfoliation of F-mica substrates, the films obtain excellent flexibility. After repeated bending in the atmosphere, the surface morphology and superconducting properties of these films substantially remain unchanged. Furthermore, we use a homemade device to apply different stains to the film and conclude that the superconducting transition temperature could be enhanced under compressive strain, whereas reduced under tensile strain. This article shows the great potential of FeSe superconducting films to integrate with future flexible electronic devices.
