Trial: Room Light Induced Antibacterial Textile

The objective of this project is to develop room-light induced antibacterial textiles. Hong Kong's hot and humid weather easily leads to bacterial growth. Public places, such as hospitals, kindergartens, nursing homes, or health-care centre, although cleaned and disinfected from time to time, the spread of bacteria still can not be avoided. There are many reasons , such as: 1 ) up to now, there is little sustainable and broad-spectrum bactericide, their performance decrease or lose over time, usually need to be applied for several times within 24 hours, but excessive use of bactericides will cause harm to human health ; 2 ) some public places were easily ignored during cleaning and disinfection, such as curtains, wallpapers, etc., they can not be cleaned or disinfected every day, easily lead to bacterial growth and spread; 3 ) because of extensive use of antibiotics or mutation of bacteria multiply itself, some resistant bacteria generated, e.g., Methicillin Resistant Staphylococcus Aureus (MRSA), it is difficult to kill these bacteria by normal bactericides. To solve the above problems, two objectives are proposed in this project: 1 ) To develop and prepare a novel visible light photocatalytic bactericide; 2 ) To use these developed bactericide to treat textiles ( e.g., curtains, wallpapers, etc. ), a sustainable and efficient antibacterial function will be achieved under the room light radiation (one of the visible light source), based on its visible photocatalytic disinfection feature. This antibacterial system will help to provide a more safe and comfortable public area to Hong Kong people, and also strengthen the competitiveness of Hong Kong textiles industry.
