QENS on the Protic Ionic Liquid Triethylammonium Triflate
Protic Ionic Liquids (PILs) are produced by combining a Brønsted acid and a Brønsted base. The main advantages of PILS for electrochemical applications arise from their anhydrous proton conductivity.The proton transfer from the acid to the base leads to the presence of proton-donor and -acceptor sites and hence of fast fluctuating hydrogen-bond network. However the dynamics of this charge carrier has not been entirely clarified yet. With this proposal we aim to shed light on the proton dynamics in the PIL triethylammonium triflate. The aim of the proposed experiments is to separate coherent and incoherent scattering contributions and thus to allow for a detail analysis of the extra dynamics observed in the partially deuterated PIL sample. We aim to study the T-dependence of both scattering contributions. In addition to the partially deuterated sample we also will investigate a completely protonated sample.
