Abstract = {{The impact of the hydrophobicity of oppositely charged additives on the
   stability of C(14)TAB foam films has been studied using a thin film
   pressure balance (TFPB). Disjoining pressure isotherms of 10(-4)M
   C(14)TAB solutions containing negatively charged sodium alkanoates
   CnOONa with increasing chain length from n = 4 to n = 12 are measured.
   The results of disjoining pressure measurements are presented as maximum
   possible pressure Pi(max) applied to a stable film as a function of the
   alkanoate concentration. Furthermore, the surface properties of the
   mixed systems are described to gain a general understanding about the
   surface characteristics. Since C14TAB and alkanoates are oppositely
   charged, the question arises whether charge reversal at the film
   surfaces occurs and how it depends on the chain length of the alkanoate.
   The presented results indicate that C(14)TAB/alkanoate systems can be
   divided into three groups. Depending on the chain length, alkanoates act
   as organic salts (n = 4), co-surfactant (n = 6) or anionic surfactant(8
   <= n <= 12). In case of alkanoates acting as anionic surfactant, the
   simulation of the isotherms by solving the non-linearized
   Poisson-Boltzmann equation under assumption of constant potential
   actually indicates that charge reversal occurs close to the nominal IEP.
   The film stabilities are markedly affected by the hydrophobicity and the
   amount of alkanoate. (C) 2014 Elsevier B.V. All rights reserved.}},
