## Description

- description: Nanomaterial-based humidity sensors hold great promise for water vapor
    detection   13because of their high sensitivity and fast response/recovery. However,
    the condensation of water in   14nanomaterial films remains unclear from a physicochemical
    perspective. Herein, the condensation   15of water vapor in silica nanoparticle
    films was physicochemically analyzed to bridge the above gap.   16The morphology
    of surface-adsorbed water molecules was characterized using infrared absorption   17spectroscopy
    and soft X-ray absorption spectroscopy, and the effect of RH on the amount of   18adsorbed
    water was observed using a quartz crystal microbalance. The adsorbed water was
    found   19to exist in liquid- and ice-like states, which contributed to high and
    low impedance, respectively.   20The large change in film impedance above 80%
    RH was ascribed to the condensation of water   21between the nanoparticles. Moreover,
    RH alteration resulted in a colorimetric change in the film’s   22interference
    fringe. The obtained insights were used to construct  an  impedance-type  portable   23humidity
    sensor with response and recovery times suitable for the real-time monitoring
    of water   24vapor in automated systems. Thus, this study clarifies  the structure
    of water adsorbed on nanomaterial surfaces and, hence, the action mechanism of
    the corresponding humidity sensors, inspiring further research on the application
    of various nanomaterials to vapor sensing.
