New polymer electrolytes (PEs), potentially interesting for solid-state
electrochemical devices applications, were synthesized by a solvent casting method
using pectin and ionic liquid (IL) N,N,N-trimethyl-N-(2-hydroxyethyl)ammonium
bis(trifluoromethylsulfonyl)imide ([N1 1 1 2(OH)][NTf2]. The resulting electrolytes besides
being moderately homogenous and thermally stable below 155 ºC, they also
exhibited good mechanical properties. The SPE membranes were analyzed by
differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron
microscopy (SEM), atomic force microscopy (AFM), and complex impedance
spectroscopy.This work was supported by FEDER through the COMPETE Program and by
