Provided is a siloxane dispersant having a structure including a head part having an affinity for nanoparticles and a tail part having an affinity for a polydimethylsiloxane (PDMS) resin, and a nanoparticle paste composition comprising the same. The dispersant significantly improves dispersion efficiency of a polydimethylsiloxane resin system which is used in preparation of high-output light sources such as UV LEDs and the like.
摘要:
Disclosed herein is a carboxylic ester dispersant shown in the following Formula 1 and a sulfide phosphor paste composition containing the dispersant. The dispersant improves the dispersibility of the sulfide phosphor paste composition and prevents oxidation by a solvent, thus improving processability and the luminescent properties of a phosphor film made from the paste and of a display produced using the film. In Formula 1, n is 1-20.
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.

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.
