Abstract

Employing the antibacterial property of industrial bamboo vinegar (IBV) and the photocatalytic degradation of TiO₂, bamboo macromolecules were pretreated and processed into nonvolatile and antibacterial bio board (NVABB). The NVABB was then analyzed by conducting Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential thermal analysis. Results show that NVABB samples had average density of 0.96 g/cm³, which is appropriate for application. In terms of physical and mechanical properties, the best NVABB sample obtained from IBV, TiO₂ and bamboo had an IBV pretreatment time of 10 min, 2% TiO₂ and 1% bamboo charcoal. Fourier-transform infrared spectroscopy demonstrated that optimum conditions for hot pressing were a temperature of 170 °C, duration of 15 min and the addition of IBV and TiO₂. Thermogravimetric analysis/differential thermal analysis curves suggest that the thermal degradation of NVABB was less than that of bamboo and that hot pressing obviously increased the thermal stability of HDBB samples. Analysis of the antimicrobial effect revealed that IBV pretreatment improves the antibacterial property of NVABB.
