Structural and thermodynamic properties of EVOH (ethylene-vinyl alcohol) based microgels and their interaction with surfactants

Abstract: Poly(vinyl alcohol) is a biocompatible water-soluble polymer of great interest thanks to its large-scale applications for production of drug-delivery systems, sensors or membranes with selective permittivity. We are currently studying a new route, which uses the salting-out effect (adding NaCl), for the preparation of PVA-based physical microgels. With the aim of extending the field of application of these systems, microgels made up of two PVA-based copolymers (EVOH), formed by ethylene and vinyl alcohol at different molar ratios, were prepared. Due to the lack of information about EVOH-based microgels in the literature, a SANS study would be fundamental to understand how different parameters, such as salt and surfactant concentration, affect the aggregation process and the thermodynamical properties of such microgel solutions.
