Abstract
Interactions between the polymers and amphiphiles in aqueous solutions have generated considerable interest among researchers because of the widespread applications, relatively complex behavior and improved physicochemical properties of the mixtures. Numerous studies on the surfactant-polymer systems have been carried out in recent years and the number of scientific reports has considerably increased. Various applications of polymers in different areas and many works concerning the amphiphiles are being published every year. Usually, the mixed systems containing polymers and amphiphiles show solution properties different from those of individual solutions due to interaction between the components. The present review article mainly focuses on the behaviour of polymers in aqueous solutions, in the absence or presence of amphiphiles, such as surfactants, drugs, etc. It also summarizes effect of the nature of amphiphiles on aggregation properties of polymers in aqueous solution, and interaction of conventional as well as gemini surfactants with polymers.
Highlights
Interaction of the polymer with amphiphile is very much significant in various pharmaceutical as well as medical industries in view of their importance in industrial products like the detergents, cosmetics, pesticides, among others
Mixtures of the amphiphile and polymer can improve the properties of the system: surfactants are generally added to control the dispersions, flocculation and wetting properties of suspensions whereas polymers are mainly added to meet rheological requirement
The research work focuses on systems with mixed interfacial films made of either two surfactants or surfactants combined with polymers
Summary
Interaction of the polymer with amphiphile is very much significant in various pharmaceutical as well as medical industries in view of their importance in industrial products like the detergents, cosmetics, pesticides, among others. Interaction of ionic surfactants with water-soluble polymers has been investigated by several researchers by different methods. The research work focuses on systems with mixed interfacial films made of either two surfactants or surfactants combined with polymers. These mixtures can have an effect on the solubilization efficiency. Effect of the addition of polymer, to surfactant systems, has been reviewed by Scottmann [2]. He has suggested that the increase of solubilization capacity occurs because of the adsorption of polymer at surfactant membranes in dilute microemulsions. The most favorable monolayer curvature and flexibility can independently be controlled by the mixed short-chain surfactant and long-chain block copolymer systems
