Anticoagulant Ultrasonic Coating for Blood Purification Membranes
In the field of blood purification therapy, improving the biocompatibility of filter membrane materials is one of the core challenges. Among these challenges, constructing a stable and uniform bioactive coating on the membrane surface, especially endowing it with highly efficient anticoagulant properties, is a key technical path to prolong treatment time and improve patient safety. Ultrasonic coating technology, as an emerging precision surface engineering technology, shows great application potential in achieving this goal, particularly in firmly and uniformly fixing natural anticoagulants such as heparin onto the surface of ultrafiltration membranes. Technical Principle: Physicochemical Synergistic Effects Surpassing Traditional Coatings Traditional coating methods, such as impregnation or spraying, often rely on intermolecular physical adsorption or simple electrostatic interactions, resulting in inherent limitations such as uneven coating, weak adhesion, and easy detachment of acti...
