| description | The invention provides a polylactic acid composite membrane and a preparation method and application thereof, the polylactic acid composite membrane comprises a polylactic acid fiber membrane, the surface of the polylactic acid fiber membrane is coated with a polydopamine coating, and hydroxyapatite nanowires are distributed on the surface of the polydopamine coating. The surface of the polylactic acid fiber membrane is firstly coated with the polydopamine coating, and then the hydroxyapatite nanowires are distributed on the surface of the polydopamine coating in an intermolecular acting force mode. Therefore, on one hand, the polydopamine coating can improve the hydrophobic property of the polylactic acid fiber membrane, so that the interface bonding force between the hydroxyapatite nanowire and the polylactic acid fiber membrane is improved; on the other hand, Van der Waals force hydrogen-bond interaction exists between the polyamine coating and the hydroxyapatite nanowire electret, so that the polyamine co |
