Antifogging and frost-resisting polymeric surfaces

Fogging/frosting can significantly reduce clarity of a transparent substrate, resulting in not only inconvenience but also potential danger in daily life. There has therefore been great demand for effective antifogging/frost-resisting surfaces to maintain visibility and transparency in high-humidity environments in a variety of applications. Although tremendous efforts have been made to prepare inorganic antifogging surfaces, the primary focus of this review is on polymeric antifogging/frost-resisting surfaces, as polymer-based antifogging/frost-resisting surfaces hold great promise for large-scale preparation via easily implementable techniques and, subsequently, find more practical applications. In this chapter, recent progress is reviewed in the design, preparation, and typical properties of various antifogging/frost-resisting polymeric surfaces.
