【摘要】 以玫瑰花瓣表面为模板,利用纳米四氧化三铁(Fe3O4)颗粒在聚二甲基硅氧烷(PDMS)印章成型过程中的加入及后处理,成功引入新的纳米结构,得到了微纳米粗糙结构优于玫瑰花瓣表面的新型仿生-再造超疏水表面,其表面润湿性优于传统方法复制的玫瑰花瓣,接触角达到169°.利用扫描电子显微镜(SEM)、X射线能谱(EDS)和接触角仪对印章进行了表征.制备的PDMS-Fe3O4印章可多次重复使用,实验过程简单、环保.更多还原

【Abstract】 In the present paper, a new bionic-recreation superhydrophobic surface, with more excellent micro/nanometric roughness and wettability than nature rose petal surface and the surface obtained through traditional micro-contact printing method, was obtained using rose petal surface as a model, based on addition and post-treatment of nanoscale Fe3O4 particles during the production of PDMS stamp to introduce new nanoscale structure, and the contact angle reached 169°. Prepared PDMS-Fe3O4 stamp could be re-used many times. Surface morphology, composition and durability of the prepared stamp were studied using scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and contact angle analyzer in detail. The experimental process is simple and environment friendly.更多还原
