The invention provides a multi-drug controllable-loading and long-acting slow-released biomedical coating material and a preparation method thereof. A preparation process comprises the following steps: polishing, washing and drying a substrate material, soaking in dopamine solution (a negative charge layer), and using a catechol-modified multi-amino biomacromolecule (with a positive charge), electronegative macromolecular solution (with a negative charge), and micelle (with a negative charge) loading multiple drugs as three components of layer-by-layer self-assembly, and preparing a coating modified material on a dopamine-processed substrate by using the above three components through a layer-by-layer self-assembly method. Multiple assembling layers can be repeatedly coated, and multiple drug molecules are largely and orderly fixed on a self-assembling coating, so that controllable long-acting release of a drug is realized.
