Description
The accumulation of dirt on glass surfaces diminishes solar panel efficiency and necessitates increased water usage for cleaning.[1] Self-cleaning capabilities can be achieved through the application of superhydrophobic coatings, which allow water droplets to remove dirt particles. Studying the interactions between charged particles and surfaces offers valuable insights into effective cleaning methods. We employed a high-speed camera with a long-distance objective to conduct an in situ analysis of the deposition of differently functionalized and charged silica dust microparticles on chemically treated glass. The ambient charges for the control, hydrophobic, and positively charged particles were measured at approximately −0.5, −0.13, and +0.5 nC, respectively. Our findings revealed that a positively charged particle with a diameter of 2.3 ± 1.2 μm adhered to hydroxylated glass in roughly 0.054 s, while it took 0.40 and 0.45 s for quaternary ammonium- and fluorosilane-functionalized hydrophobic glass, respectively. Experimental results indicate that glass surfaces functionalized with quaternary ammonium are approximately 77.8% more resistant to soiling compared to untreated surfaces.| Aikajakso | 5 huhtik. 2025 → 6 huhtik. 2025 |
