Ultrahigh Surface Area Materials And Methods Of Making Same

Competitive Advantages: Easy to manufacture, High absorption properties, Reduces noise in spectral measurements. In one embodiment, a surface has a laser-beam machined area including an array of micro-sized conical pillars that are arranged in orthogonal rows and columns across the surface and that extend upward, the conical pillars defining deep troughs between them that are configured to absorb elec­trons, electromagnetic radiation, or both, the conical pillars tapering from relatively wide bases to pointed tips, the conical pillars comprising outer surfaces that are covered with a plurality of nanoparticles.USF inventors have developed an Extremely High Surface Area (EHSA) material composed of an array of needle like structures covered in nanoparticles. The surface of the materials has superior ability to absorb radiation. These materials can potentially be used  for military applications as a coating agent to reduce radar signatures. It also finds applications in vacuum tube electron devices, scanning electron microscopy, mass spectroscopy and electron spectroscopy instruments, or wherever there is a need for radiation absorption, or isolation from EM radiation is necessary.
