Wettability is an essential property originating from liquid-solid contact and involved in various processes and applications. For fabric materials, the wettability plays important role that it can even determine the fabric's usefulness and comfort feature. This book introduces three functional fabrics, such as superhydrophobic fabric, directional water-transfer fabric, and electrically conductive superhydrophobic fabric, which are prepared by tuning the fabric wettability using wet-chemical coating technologies. It covers details about the preparation of coating materials, coating processes, and detailed characterizations of the coatings and their effects on fabric properties.
