While the potential of self-cleaning materials is vast, several challenges must be addressed:
- Cost: The production of self-cleaning materials can be expensive, limiting their widespread adoption. - Durability: Over time, the effectiveness of the self-cleaning properties may diminish, necessitating reapplication or replacement. - Scalability: Manufacturing these materials on a large scale while maintaining their unique properties can be challenging. - Safety: The use of nanomaterials raises concerns about their potential health and environmental impacts.
