WebAs mentioned in the Sec. 1, an important thermo-dynamic parameter of a surfactant adsorption monolayer is its Gibbs (surface) elasticity.The physical concept of surface elasticity is the most transparent for monolayers of insoluble surfactants, for which it was initially introduced by Gibbs (18, 19).The increments A a and AT in the definition of … WebJun 11, 2016 · An instantaneous response or Marangoni elasticity and long-time response or Gibbs elasticity. The results of the global EK for each experiment (see Fig. 7) shows that for a small forcing, the dynamics of the film are likely to be governed by the Marangoni elasticity. Contrary to large forcing where the Gibbs elasticity is dominant.
