Abstract:
The present application is directed to a nanocomposite organo gel having a continuous polymeric network structure, wherein polymer chains are held together by ionic interaction between polymer chain ends, interparticle chain entanglements, layered silicate surface modifier, ionic salt, and layered silicate. The present application is also directed to methods of making and using the nanocomposite organo gel.
