- Abstract
- A strategy to induce the directional clustering of nanopillars by controlling their tilted angles was proposed. Regularly spaced nanopillar arrays with different tilted angles of 0째, 15째, 30째, and 45째 was prepared and their clustering was demonstrated by dispersing and drying a deionized water droplet on them. By observing their clustering patterns, a simple model was developed to explain the features of tilted-angle-dependent clustering, and a criterion was proposed to classify the continuity of clustering. It was observed that the tilted-angle-dependent clustering of nanopillar arrays after drying the water droplet. It was noncontinuous and island-like with 0째?and 15째 tilt, but continuous and unidirectional with 30째 and 45째 tilt. The designed asymmetric, directional clustering of tilted nanopillars would be applicable to the directional self-assembly of high aspect ratio nanostructures and directional transport of specific materials.
