Download or read book Surfactants and Polymers in Aqueous Solution written by Bo Jönsson and published by Wiley. This book was released on 2000-01-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique book which discusses the solution chemistry of surfactants and polymers, presenting both the theory of surfactant and polymer interactions and also giving practical help for workers in this area. Surfactants are used together with polymers in a wide range of applications such as detergents, paints, paper coatings, food, pharmacy and cosmetics. Together the surfactant and polymer provide the stability, rheology, etc., needed for specific application. Hence the need for knowledge about physicochemical properties of both surfactants and polymers and polymer-surfactant interactions, to enhance formulation work. This book, based on successful courses run by the authors, brings the two topics together to enable readers to gain a good understanding of the solution behaviour of surfactant-polymer combinations. It includes a thorough description of surfactant types, including their main synthetic routes, and discusses physicochemical phenomena such as self-assembly, adsorption, gel formation and foaming. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface-active polymers are then presented and their interaction with surfactants is a core topic of the book. The choice of surfactant for emulsions and microemulsions is treated in depth and important applications of microemulsions, such as detergency and enhanced oil recovered are presented. This book will be invaluable for scientists and engineers involved in surfactant production and formulation as well as students.

Available in PDF, EPUB and Kindle. Book excerpt: Surface active agents are used as process aids in the production of polymers--as additives to impart or modify polymer properties--and in the formulation and further processing of polymeric systems for a variety of applications. In all these uses, the surfactants are used as 'effect chemicals,' to impart specific performance characteristics or properties to the base polymer or to enhance it performance when formulated for a specific end use. This volume focuses on those surfactant areas incorporating the greatest number of supplier and user companies. Authors have been selected from leading industrial and academic laboratories around the world. It provides an introduction to the underlying chemistry and technology in these industrial areas, and at the same time, highlights important recent developments. Surfactants in Polymers, Coatings, Inks and Adhesives is a book for surfactant researchers and for manufacturers and users of surfactants. In particular, surfactant chemists, analytical chemists, environmental chemists, users of surfactant formulations in the fields of specialty chemicals, polymers, and detergents, and health and safety personnel.

Outlines methods of synthesis and functionalization of self-assembled nanoparticles and the further self-assembly of the nanoparticles into one, two or three dimensional materials. Explores numerous potential applications of self-assembled structures including nanomedicine applications of drug delivery, imaging, molecular diagnostics and theranostics, and design of materials to specification such as smart responsive materials and self-healing materials. Highlights the unifying as well as contrasting features of self-assembly, as we move from surfactant molecules to nanoparticles. Written for students and academic and industrial scientists and engineers, by pioneers of the research field, Self-Assembly: From Surfactants to Nanoparticles is a comprehensive resource on diverse self-assembly systems, that is simultaneously introductory as well as the state of the art.

Download or read book Interactions Between Drag Reducing Polymers and Surfactants written by Ketan Prajapati and published by . This book was released on 2009 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drag reduction in turbulent pipe flow using polymeric and surfactant additives is well known. Although extensive research work has been carried out on the drag reduction behavior of polymers and surfactants in isolation, little progress has been made on the synergistic effects of combined polymers and surfactants. In this work the interactions between drag-reducing polymers and surfactants were studied. The drag-reducing polymers studied were nonionic polyethylene oxide (referred to as PEO) and anionic copolymer of acrylamide and sodium acrylate (referred to as CPAM). The drag-reducing surfactants studied were nonionic ethoxylated alcohol - Alfonic 1412-7 (referred to as EA), cationic surfactant - Octadecyltrimethylammonium chloride in pure powder form (referred to as OTAC-p) and commercial grade cationic surfactant - Octadecyltrimethylammonium chloride in isopropanol solvent - Arquad 18-50 (referred to as OTAC-s). The interactions between polymers and surfactant were reflected in the measurements of the physical properties such as electrical conductivity, surface tension, viscosity and turbidity. The critical micelle concentration (cmc) of the mixed polymer / surfactant system was found to be different from that of the surfactant alone. The viscosity of a polymer solution was significantly affected by the addition of surfactant. Weak interactions were observed for the mixed systems of nonionic polymer - nonionic surfactant and anionic polymer - nonionic surfactant. Due to the wrapping of polymer chains around the developing micelles, a minimum in the viscosity is observed in these two cases. In the case of nonionic polymer / cationic surfactant system, the change in the viscosity was found to depend on the polymer concentration (C) and the critical entanglement concentration (C*). When the polymer concentration (C) was less than C* (C C*), the plot of the viscosity versus surfactant concentration exhibited a minimum. When C C*, a maximum in the viscosity versus surfactant concentration plot was observed. The interactions between nonionic polymer and cationic surfactant were observed to increase with the increase in temperature. A large drop in the viscosity occurred in the case of anionic-polymer / cationic-surfactant system when surfactant was added to the polymer solution. The observed changes in the viscosity are explained in terms of the changes in the extension of polymeric chains resulting from polymer-surfactant interactions. The anionic CPAM chains collapsed upon the addition of cationic OTAC-p, due to charge neutralization. The presence of counterion sodium salicylate (NaSal) stabilized the cationic surfactant monomers in the solution, resulting in micelle formation at a surfactant concentration well below the concentration where complete charge neutralization of anionic polymer occurred. Preliminary results are reported on the pipeline drag reduction behavior of mixed polymer-surfactant system. The results obtained using combinations of CPAM / OTAC-p in pipeline flow are found to be in harmony with the interaction study. Due to the shrinkage of CPAM chains upon the addition of OTAC-p, the drag reducing ability of CPAM is compromised.

This book was released on 2012-04 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: To investigate the effect of non-ionic polymers polyvinyl pyrrolidone (PVP), polyethylene oxide and polyvinyl alcohol on critical micelle concentration of an anionic surfactant, sodium dodecyl sulfate and a cationic surfactant, cetyltrimethyl ammonium bromide at different temperatures by conductivity and surface tension techniques. The CMC of SDS decreased in presence of the polymers. The degree of this decrease in CMC of SDS was greater for PVP than for PEO and PVA. Increase in the micellar ionization degree was observed for SDS-polymer mixtures. Gcomp values for SDS-polymer mixtures were higher, more negative for SDS-polymer mixtures than pure SDS. These results showed that as compared to PEO and PVA, PVP interacts more strongly with SDS. The critical aggregation concentration of SDS-PVP, SDS-PEO and SDS-PVA mixtures slightly decreased with rise in temperature. and Gcomp of SDS-polymer mixtures increased with increase in temperature reflecting that complexation is favored at high temperatures. The krafft temperature of CTAB did not show any dependence on the concentration of the polymers.
