Development of a New Type of Large-Area Robust Superhydrophobic Surfaces (MWN)

电化学操作将被用来产生控制粗糙度和表面特征的特征尺寸在10-1000纳米范围内的坚固的金属表面。随后的表面改性（例如自组装单层，硅烷化学吸附，等离子体聚合物沉积）将使这些表面超疏水。表面将具有高度降低的粘附性能，因此显著改善了耐化学性和腐蚀稳定性。一个可行的程序，从金属表面的聚合物压印将开发。这将为廉价制造具有大面积和特定功能的各种超疏水表面的新方法奠定基础。

Electrochemical manipulation will be used to produce robust metal surfaces of controlled roughness and characteristic size of the surface features in the 10-1000 nanometre range. Subsequent surface modification (e.g. self-assembled monolayers, silane chemisorption, plasma polymer deposition) will render these surfaces superhydrophobic. The surfaces will have highly depressed adhesion properties and hence a significantly improved chemical resistance and corrosion stability. A viable procedure for the making of polymer imprints from the metal surfaces will be developed. This will form the basis of a new method for cheap fabrication of various superhydrophobic surfaces with large areas and specific functionality.
