TL;DR: New highly porous pure cellulose aerogel-like material called "aerocellulose" was prepared from aqueous cellulose/NaOH solutions, then cellulose was regenerated and dried in supercritical conditions using CO2 to obtain shaped three-dimensional objects.

TL;DR: Intrinsic viscosities of all celluloses decreased with temperature, indicating a drop in solvent thermodynamic quality with heating, and the values of the activation energies calculated within Arrhenius approximation are in-line with those obtained for cellulose of comparable molecular weights in other solvents.

TL;DR: In this article, aerocellulose is prepared via cellulose dissolution in imidazolium-based ionic liquids, 1-ethyl-3-methylimidazolate acetate (EMIMAc) and 1-butyl-3methyloridazoline N-oxide (BMIMCl), followed by regeneration and drying in supercritical CO 2 conditions.

TL;DR: In this article, a critical review of all aspects of the dissolution of cellulose in NaOH-based aqueous solutions is presented, from the background properties of the solvent itself, to the mechanisms of the cellulose fibre swelling and dissolution, solution structure and properties and influence of additives and, finally, the properties of various materials (fibres, films, aerogels, composites and interpenetrated networks) prepared from these solutions.

TL;DR: An improved method of data analysis is suggested for the determination of VTF constants and it is demonstrated that cellulose-EMIMAc solution viscosity obeys VTF formalism.
