      <dc:description>This study investigates the effect of an inert salt (NaCl) on the equilibrium interfacial&#xd;
tension and dilatational modulus of Pluronic F-68 copolymer, a triblock copolymer consisting of two&#xd;
terminal blocks of poly(ethylene oxide) and a less hydrophilic central block of poly(propylene oxide).&#xd;
Interfacial tension measurements were carried out using a surface force balance and a drop shape&#xd;
tensiometer, while rheological measurements were carried out in two different frequency ranges. This&#xd;
involved the use of the oscillatory barrier/droplet method and electrocapillary wave measurements,&#xd;
complemented by an appropriate theoretical framework. This work aimed to elucidate the influence&#xd;
of NaCl on the interfacial behavior of Gibbs monolayers of Pluronic F-68. In addition, this study&#xd;
highlights some of the technical and theoretical limitations associated with obtaining reliable dilatational&#xd;
rheological data at high frequencies (&lt;1 kHz) using electrocapillary wave measurements. The&#xd;
results provide valuable insights into the interplay between salt presence and interfacial properties of&#xd;
Pluronic F-68 and highlight the challenges of obtaining accurate dilatational rheological data under&#xd;
specific measurement conditions.</dc:description>
