CASE STUDY **Case Study: Self-Cleaning Nanopaper** **Application:** Self-Cleaning Nanopaper **Overview:** Self-cleaning nanopaper is an innovative application that combines the versatility of paper with the advanced properties of nanomaterials. This technology enables paper to repel dirt, water, and other contaminants, resulting in a self-cleaning surface that has potential benefits across various industries. **How It Works:** Self-cleaning nanopaper is created by incorporating hydrophobic (water-repellent) and oleophobic (oil- repellent) nanomaterials into the paper matrix. These nanomaterials form a protective layer on the paper's surface, altering its surface properties. When contaminants come into contact with the nanopaper, they are repelled due to the water and oil repellency of the nanomaterials. The nanomaterials work by minimizing the contact area between the contaminants and the paper surface. This reduces the adhesion forces that typically cause dirt, water droplets, or oils to stick to the surface. Instead, these substances form spherical droplets that can easily roll off the nanopaper, taking
