Title Nanostructured Materials and Interfaces: Patterning and Templating
Contents
The preparation of new polymers and nanomaterials require hierarchical levels of ordering and structuring: from molecular to macroscopic. The tools and methods available for evincing this order require design principles that start from non-covalent interactions all the way to object patterns that can be manipulated by non-lithographic methods: templating and patterning. The ability to synthesize and fabricate new macromolecules and layered ordered systems result in new material stimuli-responsive properties. We have previously highlighed the research philosophy and research methods used by our group to produce systems that include: 1) polymer brushes, 2) electropolymerized molecularly imprinted sensors, 3) electronanopatterning, 4) colloidal nanosphere lithography, and, 5) multilayer shape-stimuli patterned objects and particles. In this talk, we will specifically highlight work on nanostructured superhydrophobic coatings with stimuli-responsive properties. This is based on grafted polymer brushes with an LCST behavior and the use of templated polymer particle arrays. What is also important is the use of surface sensitive spectroscopic and microscopic analytical tools applied rationally to highlight evidence of order and function.
