26 p, 1.3 MB Study of P(VDF-co-HFP)-ionic liquid based ionogels for designing flexible displays / Santiago, Sara (Universitat Autònoma de Barcelona. Departament de Química) ; Muñoz Berbel, Xavier (Institut de Microelectrònica de Barcelona) ; Guirado López, Gonzalo (Universitat Autònoma de Barcelona. Departament de Química)
In flexible displays, solid electrolytes promote electron-transfer without compromising system integrity. Ionogels (IGs) are now preferred among other solid electrolytes, e. g. inorganic and hydrogel electrolytes, for being easier to produce than the former and showing excellent properties, including high ionic conductivities, broad electrochemical window, transparency, flexibility, and non-solvent volatility than the latter.
