Microemulsions are transparent liquid systems consisting of ternary mixtures of oil, water, and surfactants. They also exhibit water/oil continuous and bicontinuous structures, with typical equilibirum domain sizes ranging from about 10 to 100 nm. The membranes also showed temperature-dependent swelling behavior with increased water uptake at lower temperatures. The membranes were found to be effective for using in wound dressing or support for cell grafting, owing to their transparency, nanostructure and ability to sustain drug release. 关键词: Microemulsions;Polymeric membranes;Nanostructured materials;Patient treatment;Ternary systems;Surface active agents;Phase interfaces;Transparency;Thermal effects;Cells;Mixtures;Durability;Growth kinetics;Bicontinuous microemulsions;Thermosensitivity;Liquid systems;Cell grafting;Wound dressing
