Abstract
The present invention relates to microemulsions of immiscible fluids stabilized by reactive ionic liquid surfactant wherein the ionic liquid surfactant has a melting point less than 80° C. The invention also relates to composite materials comprising a copolymer of ethylenically reactive species, wherein one of the species is a reactive ionic liquid surfactant having a melting point less than 80° C., and wherein the material also comprises non-reactive Class I fluid. The invention further relates to methods for synthesizing the composite materials comprising preparing a microemulsion of immiscible Class I fluid and Class II fluid stabilized by reactive ionic liquid surfactant wherein the ionic liquid surfactant has a melting point less than 80° C., and polymerizing the microemulsion to form a composite material.
