Radiation resistant hybrid Lotus Effect photoelectrocatalytic self-cleaning anti-contamination coatings for commercial application include a direct application as protective coatings on aircraft canopies, optical sensors and on solar cell coverings. The efficiency of solar arrays can be degraded by terrestrial sources such as dust, rain, soil and other contaminants. Other applications requiring antibacterial, anti-contamination coatings include, but are not limited to: air ventilation systems and waste management structures, hospital walls and surfaces and potential application to the US NAVY Epidaurus Project (DOD Hospital of the future).
Radiation resistant Lotus-Biocide coatings have the potential to save NASA mission resources by extending the performance of components and systems, which could enhance system efficiency and ultimately extend mission durations. An extension in lifetime of components could provide a return on investment of saving millions of dollars in typical replacement parts. Potential mission applications are antibacterial, anti-contamination coatings for air ventilation systems, waste management structures, habitation airlock walls, and crew module walls and surfaces. The coating has the potential to enhance the capabilities of current life support technology and techniques by working in conjunction with those systems to eliminate contaminants. This biocide/self-cleaning technology will assist in minimizing contamination effects by neutralizing bacteria and will assist in mitigating potential health and safety issues for our astronauts. The coatings are designed to provide lunar environmental durability, suitable for use in dust mitigation applications on the lunar surface and potentially for application to satellite solar power systems. The hybrid coatings will demonstrate reduced initial contamination (>90%) compared to conventional materials and improved efficiency of cleaning processes (>99% removal of initial contamination) without damage to the surface being cleaned including cleaning in a radiation environment.
