利用亲水聚合物PMMA作为制备仿生表面的材料,以植物银杏叶为模板,原位复制表面微结构。研究了银杏叶和PMMA仿生表面的浸润性,研究结果表明PMMA可以原位复制得到银杏叶表面微结构,两者接触角区别不大。同时,在PMMA仿生表面溅射金膜,随着溅射时间的增加接触角发生改变,当溅射时间为45min时,仿生表面浸润性由亲水性转变为疏水性。 The hydrophilic polymer PMMA was used as the material for preparation of the bionic surface, and the plant ginkgo leaf was used as a template to replicate the surface microstructure in situ. The infiltration of bionic surfaces of Ginkgo biloba and PMMA was studied. The results showed that the microstructure of Ginkgo biloba leaves could be obtained by in situ replication of PMMA, and the contact angles of the two were not different. At the same time, the gold film sputtered on the bionic PMMA surface changed the contact angle with the increase of sputtering time. When the sputtering time was 45 min, the bionic surface wettability changed from hydrophilic to hydrophobic.
