Abstract Nature utilizes bottom‐up approaches to fabricate defined structures with highly complex, anisotropic and functional features. One prominent example is cacti spines, which exhibit a hierarchically structured conical morphology with a longitudinal microstructured surface. Here, a bottom‐up approach to fabricate supramolecular microstructured spines is presented by applying a self‐assembly protocol. Taking advantage of the capillary forces of vertically aligned polyamide microfibers acts as the structure‐directing substrate for site‐specific self‐assembly of a specific 1,3,5‐benzenetricarboxamides from the solution. The morphology of the supramolecular spines covers several hierarchical levels, ultimately resulting in a conical shape with longitudinal self‐assembled microgrooves and a superhydrophilic surface. It is demonstrated that these hierarchical conical microstructures are able to transport water droplets unidirectionally. |
