Trigo López, Miriam Reglero Ruiz, José A. Pablos, Jesús Luis Ciurduc, Diana Elena Corrales, T. García García, Félix Clemente García Pérez, José Miguel 2022-01 This work presents the preparation of novel solid polymer electrolytes based on flexible microporous aramids filled with photopolymerized ionic liquids and lithium salt. The materials combined a high ionic conductivity with the mechanical and thermal characteristics of the aramids, including also good flexibility and handleability. First, a simple casting process was followed to obtain microporous aramids with an interconnected channel morphology. In a second step, this channel structure was filled with a solution of non-commercial photopolymerizable ionic liquid, commercial ionic liquids and the lithium salt, followed by UV irradiation to obtain the conducting aramids. Ionic conductivity of the materials was studied at 25 °C, and also in the temperature range between −50 to 90 °C, together with SEM analyses of the filled porous structure and thermal properties, to fully characterize the photopolymerization process of the ionic liquids inside the porous structure. The materials showed high ionic conductivity values together with excellent thermal and mechanical properties, indicating their viability as flexible and thermally stable solid electrolytes. application/pdf http://hdl.handle.net/10259/6132 eng Elsevier Photopolymerization of ionic liquids in flexible microporous aramids for ion conductive solid polyelectrolytes info:eu-repo/semantics/article TEXT RIUBU.
