Title Fast ion conduction in an acid doped pentaglycerine plastic crystal Author(s) Long, S. Howlett, P. C. MacFarlane, D. R. Forsyth, M. Journal name Solid state ionics Volume number 177 Issue number 7-8 Start page 647 End page 652 Publisher Elsevier Place of publication Amsterdam, The Netherlands Publication date 2006-03-15 ISSN 0167-2738 1872-7689 Keyword(s) plastic crystal proton conduction pentaglycerine Summary High proton conductivity has been achieved in the high temperature plastic crystal phase of pentaglycerine when doped with strong acids, including trifluoromethanesulfonic acid (triflic acid) and methanesulfonic acid. The solid–solid phase transition from the ordered to plastic phase in this material occurs at 86 °C and conductivities of 10− 3 S/cm were measured in the high temperature plastic phase on the addition of 1 mol% triflic acid. In the case of methanesulfonic acid, the conductivities showed a greater dependence on acid concentration and were lower than for triflic acid, as expected on the basis of acid strengths. Electrochemical characterisation shows a clear hydrogen reduction process indicating that the proton is the mobile species in the plastic phase.
