Hello,

I did rheology of my sample composed of 1.58 wt% PEO (4000 kDa) + 5 E-06 g/kg Brij O10 (Polyoxyethylen-10-oleylether) and the reference 1.58 wt% PEO without any surfactant inside. In the presence of surfactant there is a decrease of G' and G'' dominates in a larger frequency range as it the case for the reference (attached a photo). How can this be explained - I'm trying to find publications with respect to non-ionic surfactants and non-ionic polymers but it's hard to find something. It would be nice if you have any literature. Thanks in advance.
