Abstract

The possibilities of studying thin films using quartz crystal microbalance (QCM) and quartz crystal nanobalance (QCN) on the basis of several resonances of several crystals are considered. The system of three quartz resonances is crystals used to measure various physical and mechanical properties of chitosan films with thicknesses from 50 to 200 nm. Isotherms of the water-vapor adsorption of chitosan films in the range of humidity from 0 to 99% and a temperature range of 20–70°C, the stresses in the drying film, the density, and Young’s modulus and its behavior in the temperature range are researched.
