Advanced Polymer Nanocomposites for Lunar Dust Mitigation and Surface Longevity

Lunar dust presents a significant challenge to long-term surface operations due to its high abrasiveness, strong electrostatic adhesion, and extreme environmental conditions. Existing dust mitigation strategies remain inadequate. To address this, RockyTech proposes the development of advanced polymer nanocomposite coatings that leverage a combination of mechanical compliance, optimized surface energy, and controlled surface interactions to actively reduce dust adhesion and improve removal efficiency. This six-month Phase I effort will focus on demonstrating the dust-repellent performance of lead polymer nanocomposite candidates under simulated lunar conditions. The research will investigate the interplay between surface energy and mechanical properties in dust adhesion and removal. Incorporation of hydrophobic/hydrophilic silica nanoparticles will be investigated to further tune surface properties. Experimental validation will be conducted through vacuum-based dust adhesion testing, thermal cycling from -173°C to +127°C, and plasma/UV exposure studies in collaboration with Space Dust Research & Technologies (SDRT). Dust removal efficiency will be studied using centrifugal force testing, where deposited dust particles are subjected to rotational forces to evaluate detachment behavior. The proposed coatings will be lightweight, optically clear, conformal, durable, and repairable, making them suitable for spacesuits, solar panels, optical instruments, and long duration lunar operations. If successful, this work will not only provide critical insights into lunar dust mitigation mechanisms but also position RockyTech’s materials for integration into NASA Artemis missions and commercial lunar ventures. Additionally, these coatings could serve dual-use applications in aerospace, renewable energy, and defense, where dust, radiation, and temperature extremes impact performance.
