| Abstract Scope |
Superhydrophobic and transparent coatings have gained significant attention in recent years due to their potential applications in self-cleaning surfaces, anti-fogging, and energy-efficient systems. These coatings rely on a combination of micro-nano hierarchical surface structures and low surface energy materials to achieve their unique properties. However,the development of durable, thermally stable, and self-healing superhydrophobic coatings suitable for industrial applications remains a challenge. In this study, we present a simple method for preparing a superhydrophobic and highly transparent PDMS/SiO2-TiO2-based coating using the spray-coating technique. The resulting surface exhibits a contact angle of 156.2°, a sliding angle of 2°, and a transmission rate of 90%. Furthermore, our coating demonstrated remarkable chemical and thermal stability, withstanding temperatures up to 250°C, and exceptional UV resistance even after 7 days, without any loss of superhydrophobicity. The coating also revealed self-healing properties, both chemically and thermally. In terms of application, the coated surface demonstrated good self-cleaning capability. |
