Synthesis and thermal characterization of new ammonium-imidazolium dual dicyanamide-based ionic liquids

Thermal behaviors and heat capacities of these ionic liquids were also investigated by thermogravimetry (TGA) and differential scanning calorimetry (DSC). The results suggest that the new ionic liquids have thermal stabilities up to 200 °C, as well as reasonable heat capacities in the range 25 to 100 °C.
