Data (.tif) includes:
SEM_NaTit.tif - The VEGA3 scanning electron microscope (Tescan, Czech Republic) was utilized to analyze the morphology of the fabricated material.
SEM_Tit-Zn2+EGCG.tif - The VEGA3 scanning electron microscope (Tescan, Czech Republic) was utilized to analyze the morphology of the fabricated material.
SEM_Tit-Zn2+EGCG-TMP.tif - The VEGA3 scanning electron microscope (Tescan, Czech Republic) was utilized to analyze the morphology of the fabricated material.
Data (.csv) includes:
FTIR_spectra - The tests were carried out in the reflection mode, a gold mirror was used as a background and a TE-MCT detector was used.
XPS_results - The XPS analyses were carried out in a PHI VersaProbeII Scanning XPS system using monochromatic Al Kα (1486.6 eV) X-rays focused to a 100 μm spot and scanned over the area of 400 μm x 400 μm.
Contact_angle - The contact angle measurements were conducted by depositing water droplets of ≈ 5 µL onto the sample surface, followed by recording images using a camera at 1 second and 30 seconds. From these images, the apparent edge contact angle was determined after 1 second and 30 seconds. The Attension Theta software was utilized to determine the value of apparent edge contact angle.
