Fig. 2: Parameter estimation based on DVS sample for SC1.

a Sorption isotherm of SC1 with c95 indicated in the figure. The cylinder represents the sample volume, represented as an ideal laminate. b Time-based gravimetric data converted to water concentration (kg/m3) as a result of stepwise increase of the RH between 30 and 70%. The last 20 data points represent the equilibrium water concentration per RH step. The Deff value indicated in the figure is the average of the Deff values per RH step.
