Nano-Texture Self-Cleaning Coating
Hierarchical Nano/Micro Texture Anti-Adhesion Coating
Hierarchical nano/micro-texture coating reducing dust adhesion via reduced contact area and modified surface energy — passive complement to active EDS.
Purpose
Hierarchical nano/micro-texture coating reducing dust adhesion via reduced contact area and modified surface energy — passive complement to active EDS.
Context
Child of L2-DST-COAT within the Lunar Ark system
Principles
- ▸Lotus-effect inspired hierarchical roughness
- ▸Reduces dust adhesion force by 10-100x
- ▸Passive operation (no power)
- ▸Applied via plasma deposition or sol-gel
- ▸Compatible with EDS overlay
Typical implementations
- ▸NASA Self-Cleaning Coatings (KSC-TOPS-99)
- ▸Industrial superhydrophobic coatings (terrestrial)
- ▸Biomimetic anti-fouling research
Lunar considerations
- ▸No moving parts or power
- ▸Long-life inorganic option (ceramic nano-texture)
- ▸Combined with EDS for active+passive defense
