The present disclosure relates to a polyalkylene carbonate-based resin having an excellent effect of suppressing a blocking phenomenon as well as excellent mechanical properties and thermal stability, a method of preparing the same, and a molded article prepared from the polyalkylene carbonate-based resin.

A wet gel granule of aerogel is prepared by the following steps: mixing step: mixing with an organic mixed solvent to form a mixed solution; hydrolysis step: adding an acid catalyst to the mixed solution for carrying out a hydrolysis reaction, and adding a dispersion solvent during the condensation reaction, and agitating to gel the mixed solution during agitation and produce multiple hydrophilic or hydrophobic wet gel granules of aerogel. The overall preparation speed can be shortened quickly and at the same time the hydrophilic or hydrophobic wet gel granules of aerogel wet glue particles are prepared to increase the production efficiency of the wet gel granules of aerogel.

Herein provided are methods for evaluating cellulose nanofiber dispersions, comprising the steps of: (1) preparing a cellulose nanofiber dispersion; (2) adding a color material into the cellulose nanofiber dispersion; and (3) observing the cellulose nanofiber dispersion to which a colored pigment has been added with a light microscope. The methods allow for easy evaluation of whether or not agglomerates of cellulose nanofibers exist in cellulose nanofiber dispersions, which cannot be visually determined.

A pasty composition for the manufacture of three-dimensional structures or structural elements on the surface of a substrate is formed together with a polymer as an organic component B1, and a powdery material that makes up a proportion of solid in the range of 60 mass % to 95 mass % in the composition, and at least two mutually different solvents C1 and C2 that form a solvent mixture. A first solvent C1 has a boiling temperature here that is lower than the boiling temperature of the further solvent or solvents C2.

The present invention relates to a method for producing an ionic liquid-containing structure, including: an inorganic network structure forming step of forming a network structure of an inorganic compound in the presence of an ionic liquid; and a polymer network structure forming step of forming a polymer network structure of a prepolymer and a crosslinking agent in the presence of the ionic liquid.
