摘要：
Poromechanics quantifies supercritical drying stresses during solvent exchange, pressurization and heating, and depressurization.Supercritical drying duration is minimized by accounting for the pressure dependence of permeability, viscosity and compressibility.By monitoring strain of the aerogel during depressurization, permeability can be measured as a function of pressure.The permeability of gels is found from their response to small loads or changes in temperature.
