An overview of antifogging nanocoatings: recent developments and application

Abstract

Transparent materials are essential to our daily lives. It's very well recognized that their use in windshields, cars, windows, mirrors, and eyewear makes our everyday tasks more comfortable. In addition to these, several other instances may be found in the culinary, medical, and solar industries, among other spheres of human endeavor. Unfortunately, under typical operating conditions, this material experiences fogging owing to the unavoidable condensation of water vapor on solid surface. Researchers are becoming more and more interested in antifogging nano-coatings with remarkable water repellence as a result of the growth of the coating industries and material engineering. Numerous compounds have been created by researchers thus far to prepare antifogging films. There have been reports on the mechanisms and guidelines for the creation of these agents by various technologies as a result of the core requirements of various fields. We present the latest developments in antifogging nanocoatings and antifogging performance test procedures in this review. Additionally, there has been a focus on offering understanding of the latest advancement in superhydrophobic coating through the application of nanotechnology. According to the literature, the reported antifogging films do not show sufficient results and continue to pose a practical issue that requires real-world application. As a result, antifogging techniques need to be improved further.
