Highly Transparent and Colorless Polyimide Films with Self-Cleaning Superhydrophobic Surface Prepared by Silica Sol Coating |
| 초록 |
As solar power generation increases in recent years, self-cleaning has become important because dust and dirt reduce the efficiency of solar power generation. The self-cleaning action of superhydrophobic coatings results from high contact angles of water; these surface forms spherical water droplets that can easily roll and carry dirt and dust. Colorless polyimides (CP) have been widely utilized as packaging material for the electronic industry because of their mechanical strength, as well as weather resistance. In this study, the colorless polyimide has made self-cleaning property by modifying superhydrophobic surface via the silica sol-gel method. Self-cleaning CP films were prepared by superhydrophobic surfaces using roughness of the silica. The characteristics of self-cleaning CP films, including their morphology, optical, and self-cleaning properties, were investigated. |
