Web24 nov. 2024 · Following studies investigated the ionic conductivity of cellulose derivatives, e.g. cellulose acetate, showing that the conductivity decreases by ∼ 1 order of magnitude in dry samples doped with various ion salts (e.g. LiCl) ( Barker et al., 1964a, 1964b ). WebTypical conductivity values are in the range from 1.0 mS/cm to 10.0 mS/cm. Recently, materials with conductivities above 20 mS/cm based on the imidazolium-cation were described: 1-ethyl-3-methylimidazolium thio-cyanate (Product No. 07424) and 1-ethyl-3-methylimidazolium dicyanamide (Product No. 00796 ).
