We present microemulsion systems as a new and effective cleaning medium for surfaces contaminated with highly toxic organophosphate compounds. The effectiveness of the microemulsions as cleaning agents depends not only on their ability to extract and solubilized the contaminant from the treated area, but also on the initial interactions of these complex fluids and the solid surface. Hence, we study the wetting and uptake processes of microemulsion on model surfaces, constituted by functionalized silicon wafers and porous polymer films of poly(butyl methacrylate-co-ethylene dimethacrylate). It was established that independent of the surface treated, the structure and the concentration of oil in the microemulsion have the major impact on the studied processes. According to the obtained results, we formulate a set of microemulsions able to wet and penetrate surfaces with wide range of chemical nature and morphologies.
