    摘要: A sulfide phosphor paste composition comprising a sulfur-containing dispersant, and a fluorescent film prepared therefrom, are provided. The sulfur-containing dispersant has a dual head structure containing both a carboxyl group and a thiol group or a structure containing a thiol or thiophene group as a head group. An oligomeric sulfur-containing dispersant is also provided. Adsorption of the dispersant on the surface of the sulfide phosphor prevents aggregation of the phosphor particles, and thereby improves the dispersibility of the sulfide phosphor paste composition, the homogeneity of the phosphor in the paste composition, and the density of a film produced from the paste composition. Fluorescent films and display devices produced from the phosphor paste composition exhibit improved luminescent properties and excellent processability.

    摘要: A dispersant for a more concentrated carbon nanotube solution, and a composition including the same are provided. The dispersant may have a hydrophobic chain structure with head groups capable of surrounding carbon nanotube particles. The dispersant may adsorbed onto the carbon nanotube particles. The composition may include the dispersant, an aqueous liquid medium and a carbon nanotube. The composition may further include an additive. It may be possible to produce a more concentrated carbon nanotube solution exhibiting an increase in dispersion of the carbon nanotube particles and/or more stability.
