Cellulose solutions in NaOH/water and ionic liquid (EMIMAc): Similarities and differences

Abstract : The understanding of the flow of cellulose solutions as well as their molecular organisation is a crucial need for a successful processing. The flow and molecular characteristics of cellulose solutions, cellulose/(7-9)%NaOH/water and cellulose/1-N-ethyl-3-methyl-imidazolium acetate (EMIMAc) were investigated and compared. Viscosity-cellulose concentration and viscosity-temperature dependences were built. Intrinsic viscosities were obtained considering solutions in dilute regime. Temperature increase leads to the decrease of both solvents thermodynamic quality.
