Synthesis, polymerization and conducting properties of an ionic liquid-type anionic monomer
摘要:
The synthesis of a new ionic liquid-type monomer has been performed by association of a methacrylate polymerizable group, a polar tri(ethylene oxide) (TEO) spacer, a trifluoromethane sulfonic (TFSI-) anion and a free imidazolium (EMIm(+)) cation. The ionic liquid monomer (ILM) has demonstrated a good thermal stability and a high ionic conductivity around 2.1 X 10(-3) S cm(-1) at 20 degrees C. The corresponding homopolymer has shown an ionic conductivity closely related to the monomer (6.5 x 10(-4) S cm(-1) at 20 degrees C, which confirms the ILM as a valuable monomer for the formation of polymeric ionic liquid (PIL) materials.
