Multi-Functional Carbon Nanotube Based Filtration Material

摘要

As the fibers making up a filter become smaller in diameter, the more efficient the filter is at depth filtration. Seldon Technologies has developed carbon nanotube (CNT) based filtration media (Nanomesh) that takes advantage of the inherent properties of CNTs (high strength, high surface area, electrical conductivity, etc.). Seldon's Nanomesh filters are technically disruptive because the carbon nanotubes they contain represent the ultimate limit in fiber diameter. Over the past six years, Seldon has demonstrated the feasibility of using its material to clean water, air and fuels. In 2007 Seldon was issued a patent [1] for the filtration of fluids using CNTs. Additionally Seldon has demonstrated that it is possible to produce large quantities of Nanomesh on papermaking machines largely using off-the-shelf processing equipment.
