Abstract
In this study, self-actuated photocatalyst that titanium dioxide doped by more than two transition metal was coated PU foam. The antibacterial and antifungal activity of self-actuated photocatalyst coated PU foam was characterized without light. The antibacterial property of self-actuated photocatalyst coated PU foam was shown to be reduced more than 96%, and the antifungal property was shown to be reduced more than 99.9%. The durability of self-actuated photocatalyst coated PU foam tested by Weather-O-meter showed the 7% reduction of formaldehyde decomposition from 96.5% before test to 89.8% after test. The observation of surface of PU foam coated with self-actuated photocatalyst showed that the catalyst was firmly attached to the surface of polyester fiber without separation.
