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.

An apparatus and method to determine analytes in a fluid. One aspect of the present invention is for the determination of the oil content of water using UV, near-IR, IR or Raman spectroscopy or radiometry. In certain embodiments, a solid membrane material absorbs analytes from fluid brought into contact with it. The membrane is subsequently placed in a FTIR spectrometer, which spectrometer is enabled to determine the concentration of analytes in fluid by calibration. Certain embodiments can determine the type of hydrocarbon present, and thus can differentiate Total Petroleum Hydrocarbons (TPH) from Total Oil and Grease (TOG), without any separate sample preparation.
