Flourishing Bioinspired Antifogging Materials with Superwettability: Progresses and Challenges

Abstract

Antifogging (AF) structure materials found in nature have great potential for enabling novel and emerging products and technologies to facilitate the daily life of human societies, attracting enormous research interests owing to their potential applications in display devices, traffics, agricultural greenhouse, food packaging, solar products, and other fields. The outstanding performance of biological AF surfaces encourages the rapid development and wide application of new AF materials. In fact, AF properties are inextricably associated with their surface superwettability. Generally, the superwettability of AF materials depends on a combination of their surface geometrical structures and surface chemical compositions. To explore their general design principles, recent progresses in the investigation of bioinspired AF materials are summarized herein. Recent developments of the mechanism, fabrication, and applications of bioinspired AF materials with superwettability are also a focus. This includes information on constructing superwetting AF materials based on designing the topographical structure and regulating the surface chemical composition. Finally, the remaining challenges and promising breakthroughs in this field are also briefly discussed.

Bioinspired antifogging materials with superwettability have great potential for inspiring novel products and technologies to facilitate human life, such as in eyeglasses, traffics, solar products, and so on. The outstanding performance of biological antifogging surfaces encourages the rapid development and wide application of new antifogging materials. Herein, the mechanism, fabrication, progresses, challenges, and perspectives of this material are reviewed.
