Impact of Micelle Kinetics on Interfacial Dilational Visco-Elasticity

Impact of Micelle Kinetics on Interfacial Dilational Visco-Elasticity 

Using the drop and bubble profile analysis tensiometer PAT-1 (SINTERFACE Technologies, Berlin, Germany) it is possible to perform dilational rheology studies of surfactant solutions at low frequencies. 

Expressions for the dilational visco-elasticity for non-micellar solutions E(ico) were obtained by Lucassen [57, 58]  

Equation 13.12 is identical to Equations 13.7 and 13.11, supposing the diffusion coefficient D is replaced by an effective diffusion coefficient of monomers D, according to Equation 13.4 proposed by Joos (20, 59]. 

to describe the dflatational visco-elasticity modulus of micellar solutions the model Equations 13.7-13.11 can be used. In this case we have to assume Cq = CMC for Co CMC, and have used instead of D an effective difiusion coefficient of
