dc.description.abstractSilver is being considered as the biocide for future exploration missions. Maintaining microbial control in spacecraft potable water storage and delivery systems is a significant challenge for long-duration human space exploration. The current electrolytic-based silver ion dosing system still has some challenges to be addressed and there is a need for a reliable passive silver biocide delivery mechanism. This paper describes the early stage development of a silver-based composite foam as an alternative silver dosing release technology, either to be used as a standalone, or in conjunction with the electrolytic-based systems to increase the overall system reliability. Composite foam, containing silver chloride nano particles, was synthesized and its structural properties and silver ion release rate are being optimized. This paper concerns the design, synthesis, and optimization of the silver composite foam.
