Spontaneous formation of radially aligned microchannels.
Highly ordered radially aligned microchannels are produced on the surface of polymer nanocomposite thin films via droplet evaporation. This simple, rapid, and cost-effective approach opens a new avenue for producing macroscopic surface patterns that have potential as scaffolds or substrates in the field of microelectronics or microfluidic-based biochips.
متن کاملHierarchical wrinkling patterns †
This paper reports a simple and flexible method for generating hierarchical patterns from wrinkling instability. Complex features with gradually changing topographies are generated by using the spontaneous wrinkling of a rigid membrane (titanium) on a soft foundation (polystyrene) compressed via the diffusion of a solvent. We show that the morphology of these unreported wrinkled patterns is dir...
متن کاملNested self-similar wrinkling patterns in skins.
Stiff thin films on soft substrates are both ancient and commonplace in nature; for instance, animal skin comprises a stiff epidermis attached to a soft dermis. Although more recent and rare, artificial skins are increasingly used in a broad range of applications, including flexible electronics, tunable diffraction gratings, force spectroscopy in cells, modern metrology methods, and other devic...
متن کاملControlled formation of nanoscale wrinkling patterns on polymers using focused ion beam
It has previously been shown that focused ion beam irradiation induces a wrinkled skin on the surface of polydimethylsiloxane. Here, it is demonstrated that the wavelength of the induced wrinkles and their morphology can be effectively selected by controlling the acceleration voltage and fluence of the ion beam. The capabilities of the technique are also extended by adopting the maskless patter...
متن کاملSpontaneous formation of aligned DNA nanowires by capillarity-induced skin folding.
Although DNA nanowires have proven useful as a template for fabricating functional nanomaterials and a platform for genetic analysis, their widespread use is still hindered because of limited control over the size, geometry, and alignment of the nanowires. Here, we document the capillarity-induced folding of an initially wrinkled surface and present an approach to the spontaneous formation of a...
