摘  要：
为改善竹材的疏水性和稳定性,采用软印刷技术在竹材表面仿制月季花瓣的超疏水微纳结构,同时在竹材表面负载纳米二氧化钛提高其稳定性。利用扫描电子显微镜(SEM)、能谱元素分析(EDS)、X射线衍射光谱(XRD)、傅立叶红外光谱(FTIR)、热重分析(TGA)及接触角技术对样品进行了表面特征分析。结果表明:在竹材表面成功构建了类月季花瓣表面的微纳乳突结构,水滴在其表面的接触角达到154.5°,展现出良好的超疏水特性;TGA结果显示,800℃后的样品仍有31.3%的残炭量,试样具有较好的热稳定性。表面仿生可延长竹材的使用寿命和增加竹材的附加值。

摘  要：
To improve the hydrophobic property and stability of bamboo,the super-hydrophobic micro/nano structure in a form of Chinese rose petals was built on bamboo surfaces by soft lithography,and nano TiO_2 was added onto the bamboo surface to improve its stability. The samples were analyzed for their surface characteristics by SEM,EDS,XRD,FTIR,TGA and contact angle techniques. The results showed that the papillary micro-nano structures of Chinese rose petals were successfully constructed on bamboo surface,and water droplets on the surface had a contact angle of 154. 5 °,showing a good super-hydrophobic property. TGA results showed that the residual carbon content of the sample at 800 ℃ were still 31. 3%,left with a good thermal stability. The surface bionic technology could prolong the life span of bamboo and also contributed to increased added value.
