Despite its advantages, several challenges exist in the field:
- Uniformity: Achieving uniform pore sizes and distributions can be difficult, particularly at the nanoscale. - Scalability: Methods that work well in the lab may not be easily scalable for industrial production. - Stability: Porous structures can sometimes be unstable, leading to pore collapse or material degradation over time. - Cost: Advanced techniques for controlling porosity can be expensive, limiting their use in cost-sensitive applications.
