A technique of suppressing a decrease in dispersibility of nanostructures in a nanostructure dispersion liquid that is stored or transported after production is provided. A nanostructure dispersion liquid-containing container is formed by filling an airtight container with a nanostructure dispersion liquid containing nanostructures and a dispersion medium. The nanostructures include at least one selected from the group consisting of nanocarbons, nanofibers, and nanowires, and a filling rate of the nanostructure dispersion liquid is 97 vol % or more.

A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.

A method of forming an acid-doped polyaniline (emeraldine salt) (PANi-ES) solution including steps of: (i) mixing polyaniline (emeraldine base) (PANi-EB) with a PANi-EB solvent and a gel-inhibitor to form a gel-inhibited PANi-EB solution; (ii) removing the gel-inhibitor from the gel-inhibited PANi-EB solution to form a PANi-EB solution; and (iii) adding an acid dopant to the PANi-EB solution to form a PANi-ES solution.

Some embodiments include a method of producing metal diboride nanomaterials having thickness down to the atomic scale and lateral areas from 10 nm to over 1 m by preparing a mixture of a metal diboride and a suspending solution. The suspending solution can be an organic solvent or a solution containing water, and optionally can include a dispersion agent, such as a surfactant, a polymer, small molecule, or biopolymer. Further, the method includes exfoliating the metal diboride by exposing the mixture to ultrasonic energy, centrifuging the mixture forming supernatant that includes a dispersion of exfoliated metal diborides, and extracting the dispersion from the supernatant. Some embodiments include extracting the supernatant and casting the solution by diluting the dispersion with a second suspending solution that includes dissolved polymer. This can result in a composite film includes a dispersion of the exfoliated metal diborides and provides improved mechanical properties.
