Liquids around us show various wetting patterns when they come in contact with solid surfaces, depending on their properties. This wetting phenomenon plays an important role in many industries that support our daily lives, such as paint and ink application and printing. Recently, nanoparticle dispersions, in which nanoparticles are dispersed in a liquid, have been attracting attention as a material for use in coating and printing, and new materials are being developed to take advantage of their unique properties. However, the wetting phenomenon of nanoparticle dispersions still remains a mystery.
A research group led by Associate Professor Eita Shoji, Graduate Student Ei Hoshino, Professor Tetsushi Biwa, and Professor Masaki Kubo (Graduate School of Engineering), Professor Takao Tsukada (NICHe), Professor Takaaki Tomai (FRIS) and Professor Tadafumi Adschiri (WPI-AIMR) has discovered that nanoparticle dispersions exhibit a wide range of hyperextended wetting on a substrate compared to conventional wetting behavior.
The results were published in Langmuir on December 2, 2024 and selected for the journal cover.
