A process for the preparation of porous, structured films of metals and other materials is described, through the use of liquid crystal templating. The process involves the steps of applying a thin layer of a structure-directing agent such as a non-ionic amphiphile in a solvent to a substrate and material deposited onto the substrate electrolytically. The structure directing agent forms an inverse lyotropic liquid crystalline phase. The structure directing agent may comprise phytantriol, and the inverse liquid crystal phase may be selected from Q229 (Q11P), Q224 (Q11D) and Q230 (Q11G). The porous metal film can comprise platinum or alloys thereof. The films thus produced may be used in sensors, catalysts, fuel cells, capacitors or solar cells. |
