Preparation of hydrophilic and antifouling coatings via tannic acid and zwitterionic polymers

-SBMA onto the surfaces. Water contact angle and friction coefficient tests indicated an improvement in the hydrophilic and lubricating properties of the surface after modification. Importantly, the modified surfaces exhibited a significant reduction in the adsorption of bovine serum albumin (BSA), demonstrating the excellent antifouling ability. Hemolysis tests were also conducted to assess the hemocompatibility of the coatings. The results indicated that lubricative and antifouling coatings can be easily prepared on medical material surfaces using the approach, which showed significant potential for applications in biomedical fields.
