Organosilicate is a promising material in the field of biomedical coating due to its excellent durability and biocompatibility. Especially, by selecting precursors and adding further materials, can control coating wettability which involved in adhesion of various proteins, bacteria and cells. However, superhydrophilic coatings, which have been studied in previous papers, have drawbacks such as low mechanical properties. In this study, we synthesized tertraethyl orthosilicate (TEOS) based organosilicate and added silica nanoparticles to induce additional reaction. In the above process, depending on the addition of perfluoroalkyl substances (PFAS), the solution was used in superhydrophilic or superhydrophobic coatings. The prepared superhydrophilic and superhydrophobic coatings endow the surfaces with anti-adhesion and excellent durability for various medical devices. Therefore, we have laid the foundation for the development of organosilicate-based medical coatings. |
