| Abstract: | Изложены основы метода дилатационной реологии и его применение для исследования свойств межфазных слоев на границе раздела жидкость-газ. Рассмотрены возможности метода для изучения поверхностных реологических свойств растворов ПАВ-неэлектролит, природных полиэлектролитов, систем полиэлектролит-неэлектролит и полиэлектролит-ПАВ. |
| Description: | The fundamentals of the method dilational rheology and its application for study the properties of interfacial layers at the liquid-gas were presented. The possibilities of the method for the study of surface rheological properties of solutions systems surfactant-non-electrolyte, natural polyelectrolytes, non-electrolyte-polyelectrolyte and polyelectrolyte-surfactant were considered. Important sources of information on the structure and properties interfacial layers of surfactants are their rheological characteristics. Comparison of the rheological properties of interfacial layers with their composition and internal structure determines the selection and optimization of their composition for various practical applications. These layers of surfactants are characterized by certain mechanical properties, the most significant of which are the elasticity and viscosity. These properties are caused by the ability of the surfactant molecules to interact with each other and form a structured adsorption layers. Modern experimental methods for studying the rheological properties of interfacial layers at interfaces belong to the two-dimensional (2D) rheology. There are two groups of methods of two-dimensional 2D rheology. This rotational viscosity measurement methods modulus at imposing strain shear and dilatational rheology measurement when applied strain tension-compression. Increasingly used methods found dilated rheology. These methods are used in modern laboratory practice and implemented in the form of original and commercial devices |
