Superhydrophobic surfaces with high adhesion have attracted huge attention in recent research works due to their versatile applications including transportation of microdroplet without any loss. Modification of metallic surfaces to achieve such properties is important to extend their applications. Especially, the superhydrophobic surfaces with very low bacterial adhesion have attracted intense attention in medical, food, and pharmaceutical industries. Here, we have fabricated different micropatterns on aluminium surfaces using a simple and cost-effective micro-imprinting technique. The surface chemistry was modified through a coating of low surface energy material 1H, 1H, 2H, 2H-perfluorooctyl-trichlorosilane (FOTS) using vapor deposition technique. Surface morphology of the samples was investigated using scanning electron microscopy (SEM) and contact profilometer. Results show a significant influence of the surface morphology on the wetting, adhesion and anti-bacterial properti...

形貌和化学处理对微图案铝表面疏水性和抗菌活性的影响

具有高附着力的超疏水表面由于其用途广泛，包括微滴的运输而没有任何损失，因此在最近的研究工作中引起了极大的关注。对金属表面进行改性以实现此类特性对于扩展其应用非常重要。尤其是，具有极低细菌粘附力的超疏水表面在医学，食品和制药工业中引起了广泛的关注。在这里，我们使用简单且经济高效的微压印技术在铝表面上制作了不同的微图案。通过使用气相沉积技术涂覆低表面能材料1H，1H，2H，2H-全氟辛基三氯硅烷（FOTS）来改性表面化学。使用扫描电子显微镜（SEM）和接触轮廓仪测量样品的表面形态。结果表明，表面形态对润湿性，附着力和抗菌性能有显着影响。
