While surface structuring offers numerous benefits, it also presents several challenges:
1. Precision: Achieving the desired structure at the nanoscale requires extremely high precision, which can be difficult and costly. 2. Scalability: Many techniques used for surface structuring are not easily scalable for mass production, limiting their industrial applications. 3. Material Limitations: Not all materials are suitable for certain structuring techniques, which can restrict the choice of materials. 4. Stability: Nanostructured surfaces can be less stable and more prone to degradation over time, affecting their long-term performance.
