The extensional and dynamic surface tension properties of a set of associative polymer-surfactant Boger fluids have been characterized. When combined with the already understood structural phenomena of this anionic surfactant-nonionic polymer complex, the results of this study provide great insight into the benefits of utilizing polymer-surfactant complexes to tune fluid properties during rapid, high-deformation processing scenarios. The dynamic surface tension behavior observed for the associative polymer-surfactant mixture investigated elucidates new insights into the enhanced surface adsorption of the complex to the air-water interface over that of the pure-component solutions alone at concentrations below the commonly referenced critical aggregate concentration (cac) of the complex. The dynamics of extension of this set of constant-viscosity elastic (Boger) fluids were seen to change substantially as increasing amounts of associative surfactant were present in solution, with the polymer-surfactant solutions displaying faster rates of strain hardening at lower rates of extension than the pure polymer solution. Such significant changes to the dynamics of extension of these dilute polymer solutions upon the addition of an associative surfactant are shown to be responsible for the observed recoil suppression during a drop impact-event on a hydrophobic surface. The enhancement of extensional properties of the solution at lower extension rates far outweighs the advantages provided by the presence of fast-acting surfactants at the air-water interface. These outcomes provide detailed evidence that significant synergy remains to be explored with respect to drop impact behavior and the addition of associating surfactants to dilute polymer solutions in industrial formulations.
