About this technology

Overview

Innovators at NASA Johnson Space Center have developed a novel method to load filter media substrates with pristine graphene nano-particles that significantly boosts water-filtering performance. Although this proof-of-concept was originally developed to apply the graphene to existing filtration media, it could also be used for graphene-only filtration. Ensuring the longevity of water-filtration media is crucial to providing potable water throughout space-based mission timelines along with decreasing upmass and increasing precious cargo volume for other payloads during resupply missions to the International Space Station (ISS). Future manned deep-space missions will have an even greater dependency on efficient water reclamation systems as filtration media resupply may not be feasible. The graphene nanoparticle loading technique presented was developed to facilitate the extended life of inert or active filtration media by signif-icantly increasing its contaminant-trapping ability. This method is designed for flow-through packed bed filtration systems and allows graphene to be incorporated into ion-exchange resins, polymer foams, or other substrates, potentially enabling applications across multiple terrestrial product lines.
