Electrochemical applications of electrolytes based on ionic liquids
Neto, M. J.; Leones, R.; Sentanin, F.; Esperança, J.; Medeiros, Maria José; Pawlicka, A.; Silva, Maria ManuelaThe potential utility of room temperature ionic liquids as electrolytes in current electrochemical applications has been explored. Hence, the electrochemical behavior of [Ni(tmc)]Br2 complex at a glassy carbon electrode in the absence or in the presence of unsaturated halides in the ionic liquids, 1-ethyl-3- methylimidazolium ethylsulfate, [C2mim][C2SO4] and N,N,Ntrimethyl- N-(2-hydroxyethyl) ammonium bis(trifl...
Synthesis and electrochemical characterization of aPEO-based polymer electrolyte
Rodrigues, Luísa; Silva, Maria Manuela; Veiga, H.; Esperança, J.; Costa, M.; Smith, Michael JohnIn this paper the preparation and purification of an amorphous polymer network, poly[oxymethylene-oligo(oxyethylene)], designated as aPEO, are described. The flexible CH2CH2O segments in this host polymer combine appropriate mechanical properties, over a critical temperature range from -20 to 60 ºC, with labile salt-host interactions. The intensity of these interactions is sufficient to permit solubilization of...
