ИСТИНА

A new kind of soft hydrogel materials, composed of two interpenetrating networks, one consisting of dynamically cross-linked polymer chains and the other of entangled wormlike surfactant micelles, was developed [1-3]. The networks interlaced into a bicontinuous structure because of the segregation between polymer-rich and surfactant-rich microphases. The resulting material demonstrates significantly enhanced rheological properties as compared to the individual components taken separately, whereas dynamic character of the cross-links in the first network and non-covalent chains of the second network provide to the hydrogel a high responsiveness to external triggers. Such materials are very promising for the application in many areas, ranging from enhanced oil recovery to biomedical uses. Acknowledgement.
