N2 - When the channel size was reduced to 10-100 nm space, which we call extended-nano space, various unique liquid properties were observed in SiO2 nanochannels for protonic solvents. SiOH groups on the substrate were verified to work as proton donors and affected the liquid property change. However, there is no investigation of the dependence on other proton-donor functional groups. In this presentation, the nanochannels were formed on a TiO2 material (photocatalytic material), which also included TiOH groups as proton donors and was expected to show the similar unique liquid properties. Finally, we verified that the viscosity increased for water confined in the TiO2 nanochannels as well. This results have a large impact on the nanofluidic sciences, when the various functional surface materials are used.
