Abstract:

The small samples of China fir (Cunninghamia lanceolata)/TiO2 composite were made by sol-gel method and MWLPD (microwave assistant liquid phase deposition) method for the first time (XRD result shows the size of crystal TiO2 are 16.4 and 28.3 nm respectively). It has been verified by antibacterial testing that the antibacterial rates of samples reach up to above 90%. Escherichia coli, Salmonella typhimurium, Staphylococcus aureus and Bacillus subtilis were regarded as testing target in the antibacterial testing. The antibacterial function of samples is long lasting and broad spectrum. The testing result shows that the antibacterial effect is influenced by light supply and testing temperature. Introducing the TiO2 nanotechnology as photocatalysis antibacterial agent into wood industry will promote wood modification and development of multi-function wood product.

Key words: China fir (Cunninghamia lanceolata), China fir/TiO2 composite, photocatalysis antibacterial agent, antibacterial rate, antibacterial property
