Abstract:
A donor substrate (10) for forming multiple thin films of material (12). In one embodiment, a first thin film of material is separated or cleaved from a donor substrate by introducing energetic particles (22) through a surface of a donor substrate (10) to a selected depth (20) underneath the surface, where the particles have a relatively high concentration to define donor substrate material (12) above the selected depth. Energy is provided to a selected region of the substrate to cleave a thin film of material from the donor substrate. Particles are introduced again into the donor substrate underneath a fresh, or cleaved, surface of the donor substrate. A second thin film of material is then cleaved from the donor substrate.

Aligned carbon nanotube-polymer composite materials, systems and methods include a substrate that carries an adhesive coating thereon. A plurality of carbon nanostructures are adhered to the substrate by the adhesive coating, such that the nanostructures are formed into a predetermined architecture, such that the architecture of the nanostructures defines at least one orientation for a plurality of nanostructures, and defies the approximate spacing between the nanostructures and/or groups of nanostructures. The adherence of the carbon nanostructures in the adhesive coating stabilizes the predetermined architecture of the nanostructures, such that the architecture renders the composite material superhydrophobic.
