Structure and rheology of mucus and lungsurfactants. KU Leuven
In the first part of this work, a complete analysis of the effect of temperature and surface pressure on the interfacial shear rheology of the main lung surfactant phospholipid DPPC is performed. The monolayer is shown to behave as a viscoelastic liquid with a domain structure. At low frequencies and for a thermally structured monolayer, the interaction of the molecules within the domains can be probed. The low frequency limit of the complex ...
