Preparation and characterization of antibacterial hybrid coats

In this study, TMSPM and TEOS binder-based hybrid coatings with thyme oil, black pepper oil, cumin oil and tea tree oil were applied to polycarbonate (PC) and polymethyl methacrylate (PMMA) surfaces. Hybrid coating surfaces are thermally and UV cured. Coated PC and PMMA polymer surfaces were characterized by FTIR analysis, digital microscope imaging, contact angle analysis and antifungal sensitivity. The contact angle is 87.84 ° for the uncoated PC and 95.89 ° for the PMMA. Characteristic peaks were obtained for TEOS, thyme oil, cumin oil, tea tree oil and black pepper oil in FTIR analyzes. Thickness in the range of 2.059-49.322 µm was obtained for digital microscope images. In the anrifungal susceptibility test, the additional effective ones for Aspergillus flavus mold followed the order of thyme oil, tea tree oil, cumin oil, TEOS and black pepper oil, respectively.
