Tunable Surface Topographic Control Through Nanofabrication (Data Management Plan)
Abstract
We predict that precisely designed and controllable surface features can manipulate and tune surface functionality. Bottom-up fabrication of soft materials with aligned embedded nanoparticles may be stimulated through an external stimulus to change geometry, and thus, function, on demand. In this case, the height and shape of surface micro/nanofeatures could be isotropically or anisotropically altered with embedded nano-ferromagnetic particles influenced by a magnetic field. The proposed magnetic responsive micro/nanofeature array can change surface properties by rapid manipulation of the aspect ratio of the feature, dependent upon the applied magnetic field strength under the feature array, the embedded magnetic particle magnetization, and the soft elastomer modulus modification. To increase our control over the topographical modification, we will correlate material properties and embedded constituents to the deformation tolerance, actuation speed, and concentration of the magnetized ferromagnetic particles in micro/nanofeatures.
