                      dissolution of cellulose in binary mixtures of common polar
                      organic solvents with ionic liquid. Cryogenic transmission
                      electron microscopy, small-angle neutron-, X-ray- and static
                      light scattering were used to investigate the structure of
                      cellulose solutions in mixture of dimethyl formamide and
                      1-ethyl-3-methylimidazolium acetate. Structural information
                      on the dissolved chains (average molecular weight ∼5 ×
                      104 g/mol; gyration radius ∼36 nm, persistence length
                      ∼4.5 nm), indicate the absence of significant aggregation
                      of the dissolved chains and the calculated value of the
                      second virial coefficient ∼2.45 × 10–2 mol ml/g2
                      indicates that this solvent system is a good solvent for
                      cellulose. More facile dissolution of cellulose could be
                      achieved in solvent mixtures that exhibit the highest
                      electrical conductivity. Highly concentrated cellulose

                      of a volatile co-solvent in binary solvent mixtures at
