Abstract

Mixtures of polymers and surfactants in water are versatile systems used in formulating foams across a spectrum of industries, including food, cosmetics, pharmaceuticals, and oil, among others. The kinetic mechanisms governing the transfer of surfactant (S) and polymer (P) molecules, as well as their complexes (PS), from bulk to the interface, are pivotal in both the production and stabilization of aqueous foams. Despite its critical role, dynamic surface tension of PS mixtures remains relatively underexplored. This article aims to critically review the literature regarding our current understanding of the adsorption dynamics of polymer–surfactant mixtures at the air–solution interface. Special emphasis will be placed on the kinetics of adsorption during short, far-from-equilibrium times, which are crucial in determining the foamability of a system. The article will highlight the significance of P–S interactions and dynamics in the bulk for a comprehensive understanding of the adsorption dynamics at fluid interfaces.

期刊介绍： Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
