Regenerable Fused Carbon Nanotube Filters for CB Agents

Regenerable HEPA air filters of high reliability and efficiency, which not only capture but inactivate toxic chemical and biological warfare/terrorism agents, are urgently required for personal protective equipment for first responders and soldiers, and for building HVAC systems. These filters must have low resistance to air flow and long lifetimes, and not allow captured toxic materials to be released. This program will apply the revolutionary technology of Seldon Laboratories' proprietary fused carbon nanotube membranes for the protection of individuals as well as buildings. Filter membranes will be constructed, and will be tested for effectiveness against contaminants analogous to relevant toxins. They will be regenerated while their performance and condition are monitored, to determine feasibility of regeneration in actual CB agent protective applications. Based on test data obtained for different combinations of filter designs and regeneration methods, prototype filters will be designed in Phase I. They will be constructed in the Phase I Option period, and in Phase II further evaluated, optimized, then tested with live agents in simulated conditions representative of field use in CBW/terrorism scenarios.
