With a total of 6 patents to her name, her work has implications in various industries, including environmental and energy sectors.

Latest Patents

One of her latest patents is a method for producing an aqueous foam. This method involves preparing a solution that includes at least one surfactant and a protic polar solvent. The solution is then brought into contact with a pressurized gas to create a two-phase mixture. This mixture is injected to produce the aqueous foam after the gas expands or disperses. The solution also contains at least one gelling compound, which can be a non-nitrogenous polysaccharide or gelatin. The resulting aqueous foam has applications in decontamination, purification of effluents, and the defusing or containment of explosive devices.

Another significant patent involves polyphenylene-type polymers. This invention relates to polymers that include phenylene units, with at least one unit bearing a phenylene side group substituted with a perfluoro group or chain. This side group is further substituted with functional groups such as —SOH, —POH, or —COH. The polymer is particularly useful for making fuel cell membranes, showcasing its potential in energy applications.
