Preparation of Epoxy/Jeffamine Networks Modified With Phosphonium Based Ionic Liquids
Résumé
This study investigates the influence of different ionic liquids (ILs) based on tetraalkyl-phosphonium cations on the dynamic-mechanical, ionic conductivity as well as morphology of epoxy resin based on diglycidyl ether of bisphenol A cured with poly(propyleneglycol) bis(2-aminopropyl ether), aiming to develop new thermosetting systems with confined ionic liquid. The ionic liquids include trihexygtetradecyl)-phosphoniumdicyanamide, trihexyl(tetradecyl) phosphonium-bis(trifluoromethane-sulfonyl)imide) and tributyl(tetradecyl) phosphonium-dodecylbenzenesulfonate. The effect of these ILs on the morphology, dynamic-mechanical, ionic conductivity and tensile properties of DGEBA networks is investigated.
