Última Moisture sorption in polyamide 6.6: experimental investigation and comparison to four physical-based models ArchiMer Broudin, Morgane; Le Saux, V.; Le Gac, Pierre-yves; Champy, C.; Robert, G.; Charrier, P.; Marco, Y.. Water sorption in polyamide 6.6 has been characterized for a wide range of temperature (25°C to 80°C) and various water activities using a Dynamic Vapor Sorption testing machine. Complex sorption mechanisms govern the water uptake in the material. The competition between two main temperature dependant mechanisms has been observed: a Henry’s sorption mechanism that mainly governs the sorption curve at low water activities, and a second mechanism at high water activities that could be related to the formation of water clusters. It is observed that the temperature dependency can mainly be attributed to the Henry’s contribution. Four physically based models are then used and identified thanks to the extended experimental database. It is shown that a simple...
