| 摘 要： | 采用溶胶-凝胶法,在低温条件下制备TiO2溶胶,并利用溶胶在竹材表面负载成膜,完成竹材的TiO2改性,同时利用场发射环境扫描电镜(FESEM)、X射线衍射仪(XRD)、X射线能谱仪(EDAX)对改性竹材、TiO2进行形貌及结构表征,并重点研究温度、负载次数对TiO2晶型及防光变色性能的影响。结果表明:改性竹材表面负载了径级在40～90nm之间的TiO2颗粒薄膜,可提高竹材的抗光变色性能,其中热处理温度为105℃、经3次负载后的改性竹材,在经过120h加速老化后,其总色差约为空白试样的1/2左右。

| Abstract: | Bamboo,a kind of forest resources only less important than wood,is especially easy to mildew and discolor during outdoor service. In this work,TiO_ 2 sols were synthesized under low-temperature condition by sol-gel method. The crystalline TiO_2 film with a diameter of approximate 40-90 nm was coated on the bamboo at low temperature. The TiO_2 films were characterized by field emission scanning electron microscope(FESEM),X-ray diffraction(XRD) and energy dispersive X-ray analysis(EDAX). The effect of tempera... |
