Abstract In the quest for advanced coatings suitable foldable electronics and photovoltaic systems, there is a pressing need materials that combine transparency with durability. To address this, innovative special horizontal stripes transparent (SHT) coating prepared by capillary gravity self‐assembly methods. This derived from structural principles of corn bracts created through crosslinking epoxy hydrophobic modified SiO 2 an organosilicon prepolymer, bridged double terminal amino polydimethylsiloxane. The pattern surface makes SHT more than glass, bionic structure proven to be highly durable under extreme temperature fluctuations, withstanding tests 150 −20 °C over 192 h, enduring 30 days ultraviolet radiation exposure at 365 nm intensity W m − . Moreover, even after 3000 cycles scissors abrasion, maintained its anti‐fouling properties mechanical resilience. It also demonstrated remarkable chemical stability across range solvents. can easily applied various flexible rigid substrates using brush, poised find broad applications in realm optical devices.

Anticounterfeiting technologies have become increasingly crucial due to the growing issue of counterfeit goods, particularly in high-value industries. Traditional methods such as barcodes and holograms are prone replication, prompting need for advanced, cost-effective, efficient solutions. In this work, a practical application anodic aluminum oxide (AAO) membranes presented anticounterfeiting, which addresses challenges high production costs complex fabrication processes. Unlike previous approaches requiring metal coatings color generation, method uses commercial foils produce colorful AAO without layers. Elemental mapping suggests that impurities on surface contribute enhanced reflectivity, aiding photonic crystal formation. A two-step anodization process creates patterned is further introduced, with pattern clarity controlled by time. Additionally, pH-responsive film composed 2-anilino-6-dibutylaminofluoran (ODB-2) thermoplastic polyurethane (TPU) integrated, enabling dynamic changes under varying pH conditions, enhancing anticounterfeiting functionality. This streamlined approach provides scalable cost-effective solution developing versatile industrial applications.
