Application of a Fused Carbon Nanomaterial Filter for Lunar Dust Abatement, Phase I

Seldon Laboratories, LLC, will apply its patented carbon nanotube filtration technology for air and nanoscale particulate engine exhaust filtration to NASA's Lunar Exploration challenges. This project focuses on the problem of efficient removal of nanoscale (10-100nm) and larger lunar dust particulates from air using a nanostructured fiber media containing carbon nanotubes. Lunar dust presents an important challenge to Lunar exploration and habitation, nonetheless it has some unique properties that can be taken advantage of in designing specialized filtration media capable of achieving efficient removal from air. The rough surface shape combined with the electrically and magnetically charged nature of the dust means that rough, electrically activated filtration media will be effective tools for filtration. Seldon's work with its proprietary fused carbon nanotube media offers a unique path to significant new purification applications that meet important needs for NASA's Lunar Exploratory Initiatives. The unique physical properties of the carbon nanotubes will be capitalized upon to create a filtration media with high efficiency and low pressure drop that can be electrically powered to enhance filtration of charged lunar dust particles.
