In different application areas, bacteria cause serious problems due to their occurrences in a bio-film form on the surfaces. To overcome such drawbacks, surface coating appears as an alternative way to prevent these formations. In practice, there are many antibacterial substances and biocides for coating the material surfaces. With this strong motivation, the present study addresses a closer look at silane-based anti-bacterial coatings on polycarbonate. For anti-bacterial purposes, silver oxide, boron oxide, and titanium oxides in nano-sizes were utilized with the combination of silanes. The samples were prepared using the traditional sol-gel technique. After that, silane-based hybrid coating surfaces were cured with thermal treatment. The synthesized samples were analyzed using Fourier Transform Infrared Spectroscopy, digital microscopy, and anti-bacterial activity. As a result, we reported that our samples showed an anti-bacterial behavior.
