Two glass transitions in N,N-diethyl-N-methyl-N-(2-methoxyethyl) ammonium tetrafluoroborate-H2O mixed solutions
For a room temperature ionic liquid, N,N-diethyl-N-methyl-N-(2-methoxyethyl) ammonium tetrafluoroborate, [DEME][BF4]-H2O system, we have observed two glass transitions in the region of 16.5-30.0 mol% H2O. The nano-phase separations in [DEME][BF4] enhanced by a small amount of H2O may be the cause for this. (C) 2010 Elsevier B. V. All rights reserved.
