摘要/Abstract

摘要： 以美人蕉叶为模板，采用二次复型方法制备PVA/PS、PDMS/LDPE超疏水材料。通过SEM观测材料表面形貌特征，并采用接触角测量仪测试水滴在材料表面的接触角和滚动角。结果表明，二次复型的聚合物表面成功复制了美人蕉叶的微纳复合结构，PVA/PS材料的接触角高达156°，滚动角为47°，PDMS/LDPE材料的接触角可达140°，滚动角大于90°，疏水效果均比平滑材料有显著提高。

Abstract: Canna leaf was used as the template to prepare the super-hydrophobic materials of PVA/PS、PDMS/LDPE by double replication technology. Using the SEM to observe the morphology of these materials and the contact angle meter was employed to test the static angles(CA) and sliding angles(SA) of water droplets on these surface. The results show that the surface of polymers successfully replicated the micro-nano structure of canna leaf. The CA of PVA/PS is 156° and its SA is 47°, the CA of PDMS/LDPE is 140° and its SA is greater than 90°. The hydrophobicity of these two replicas are significantly enhanced than the flat materials.
