Stability of organic materials properties is essential for further applications and was intensely investigated in last few decades. The aim of this study is to detect the structural changes of dipalmitoyl-phosphatidylcholine (DPPC) monolayer as a model system of organic material under influence of alcohols solutions. As subphases of monolayers (Langmuir films), pure water, ethanol and methanol solutions were used. For detection of changes in charge states of the molecules as well as relation with structural and conformational changes, a contactless method employing Maxwell's displacement currents (MDC) was used. In DPPC monolayer on the subphase of methanol-water, a gradual absorption of methanol molecules into the layer can appear. In DPPC monolayer on the subphase of ethanol-water adsorption of ethanol molecules on the layer can be observed. Influence of alcohols results in a significant change of mechanical and electrical properties as well as in the stability of thin films.

“…Calculating adsorptive near-interface mass transfer creates the need for effective diffusion coefficient estimation. First approach to dynamics of the interface adsorption was presented by Ward and Tordai [72] who formulated first quantitative model of diffusion controlled adsorption, then the mixed adsorption kinetic model proposed by Baret [73] and, further, short and long time approximations proposed by Feinermann [74]. The thermodynamic description of system containing interface in the form of free energy functional is widely discussed [75][76][77][78][79] and also the detailed presentation of the models used to describe the adsorption processes at the liquid-liquid interfaces can be found in literature [80].…”

The work presents a new modeling technique designed for transporting selected property while simultaneously tracking particular value of certain field variable. The model addresses the problem of transportation of superficial properties according to fluid/fluid interface evolution. Such problem arises when some superficial variable needs to be attached to the evolving interface or front defined. Several multiphase models in CFD technique lack such ability. The model proposed is illustrated by the experimental two phase system of toluene/water with surfactant specie (sodium dodecylsulfate SDS). The selected superficial property that is important to be tracked according to interface evolution is Gibbs surface excess. The computation was performed using Ansys/Fluent software with proposed models created and attached using C programming language.
