摘要:

采用两步法将TiO2/ZnO纳米材料与杨木试样复合, 制备了纳米二元负载木材. 通过X射线衍射(XRD)、 傅里叶变换红外光谱(FTIR)和扫描电子显微镜(SEM)对样品的结构和形貌进行了表征, 并探讨了不同处理条件下得到的纳米氧化物负载木材及非纳米氧化物负载木材的抗菌性和耐候性. 结果表明, 氧化锌和二氧化钛二元协同负载木材的抗菌性和耐候性均优于单一纳米晶处理的木材; 在溶剂热反应中以正己烷作为溶剂所制备样品的性能优于以水和无水乙醇为溶剂制备的样品; 并且纳米结构负载木材的抗菌性和耐候性优于非纳米结构负载的木材.

Abstract:

Nano TiO2/ZnO binary collaborative wood was prepared via two step method. The structure and morphology of the samples were characterized by X-ray diffraction(XRD), Fourier transform infrared spectrometer(FTIR) and scanning electron microscopy(SEM), while its antibacterial and weather resistance properties under different preparative conditions were also investigated. According to the results, nano TiO2/ZnO binary collaborative wood shows better performance than those treated by single nanomaterial in both properties, and n-hexane treated ones are better than those treated by anhydrous ethanol or distilled water, and wood with nano oxide shows better than those with non-nano oxide.

Key words: Binary collaborative, Zinc oxide, Titanium dioxide, Nanoscale metal oxide
