Highly flexible and biofriendly ionogels are produced by gelation of microcellulose thin films with 1-ethyl-3-methylimidazolium methylphosphonate ionic liquids. The obtained ionogels can be laminated onto any substrate such as paper and act as high capacitance dielectrics for electrolyte-gated inorganic (ZnO) and organic (P3HT) field-effect transistors. They operate at very low voltages (<2 V) and enable the fabrication of flexible circuits on multilayer-coated paper.
