| Abstract: | Ultra-violet light absorbility of the functional coatings is studied by UV-visible light absorption spectrometry. Bacteria community counting method is used to study their bacteria- resistance to staphylococcus aureus in visible light. This paper analyzes the influence of nano-powder, inlet capacity and inlet manner on UV light absorbility and bacteria-resistance. |
