Abstract
Ammonia gas senior which has a high sensitivity in robust condition has investigated. Nano-porous thin film consisted of polyelectrolytes and sheet particulate α-ZrP was assembled by a layer-by-layer self assembly method on a electrode of quartz crystal microbalance(QCM). This QCM sensor showed a eight times higher sensitivity than that of QCM deposited with n-ZrP by a casting method in low relative humidity. This means that the polyelectrolytes were worked as not only a stabilizer to form a porous structure but also as a material to keep moisture. Consequently, we considered that the gas sensitivity of thin film was increased for other hydrophilic gases.
