Mechanically Robust Hybrid Coatings for Antifogging, Antireflection, and Self‐Cleaning Applications

Abstract

AbstractIn this work, a novel multifunctional film with durable antifogging performance and remarkable optical property is designed. By doping and hybridization to build an organic–inorganic siloxane network, the surface achieves long‐lasting wettability and superhydrophilicity with a water contact angle of 0°, which is maintained within 10° for over 130 days. The low refractive index endows the hybrid film with excellent optical property, which the average transmittance (380–1100 nm) of the film is 97.60% with the peak transmittance of 99.48%. By this design, the film performs well in the felt abrasion test, water impact test, X‐cut tape test, tape‐peeling test, chemical stability test, and anti‐dust test. Due to the abundant hydroxyl radicals on the surface, the film also exhibits excellent performance, achieving 92.73% degradation of methylene blue solution (10 ppm) and 39.53% degradation of rhodamine B (10 ppm) with good reproducibility in cyclic measurements.
