Lunar dust poses significant challenges for future lunar missions due to its high adherence,
abrasive nature, and electrostatic charging behavior. This thesis investigates the development
of an antidust coating composed of polyimide and alumina platelets, employing a layer-by-layer deposition approach to enhance durability and antidust performance. The study explores the fundamental adhesion mechanisms governing particle-surface interactions, including van der Waals, electrostatic, and capillary forces, and evaluates the coating’s performance under lunar relevant conditions.
A custom-designed vacuum chamber was utilized to simulate the lunar environment, allowing
for systematic dust adhesion measurements under varying pressure and electrostatic conditions. The results demonstrate that the coating effectively reduces dust adhesion through
both material composition and electrostatic repulsion. The multilayer structure ensures longterm functionality by allowing self-renewing exposure of alumina layers upon wear.
This research contributes a novel approach by integrating surface energy matching with
electrostatic repulsion to minimize lunar dust accumulation. These findings provide a foundation for further development of durable antidust coatings, crucial for the success of future lunar missions.
