- Abstract
Responsive bottle-brush macromolecules undergo vapour-induced spreading and dewetting cycles on facetted SrTiO3 surfaces with a saw-toothed topography. The macromolecular transformations are followed by environmental scanning force microscopy in real time. A set of the wafers with different groove periods are tested as the substrates for the transforming macromolecules. In order to estimate the orienting influence of the anisotropic patterned substrate, an asymmetry factor is measured for the dewetting macromolecules at different groove periods. The most evident template influence of the substrate occurs when the period is in range of 20-40 nm. This range is commensurable with the typical lateral dimension of the adsorbed bottle-brush macromolecules with a dense flat corona of extended side chains.
