  • Patent number: 7662317
    Abstract: Provided is a dispersant including a hydrophobic moiety with a branched alkyl group and an arylene group and a hydrophilic moiety with an alkylene oxide group and a carboxylic acid group. The alkyl group is a substituted or unsubstituted alkyl group of 5-30 carbon atoms, the arylene group is a substituted or unsubstituted arylene group of 6-30 carbon atoms, and the alkylene oxide group is a substituted or unsubstituted alkylene oxide group of 2-10 carbon atoms. The dispersant has good dispersibility, and a low residual carbon content after sintering. Thus, a paste composition including the dispersant can maintain a low viscosity and disperse many inorganic particles. Thus, an inorganic device prepared using the paste composition can have a low residual carbon content and a high packing density.

  • Publication number: 20100025640
    Abstract: Method for the preparation of inorganic-NP-composite microgels is based on the reversible transfer of microgels between water and an organic solvent such as tetrahydrofuran (THF). The method is used to produce semiconductor nanocrystals, often referred to as quantum dots (QDs) which are well known for their unique optical, electrical, magnetic and catalytic properties, as the inorganic NPs, recognizing that the best quality QDs are synthesized by a high temperature process in organic media, and have their surface covered with hydrophobic ligands (such as trioctylphosphine oxide, TOPO) that render the NPs insoluble in an aqueous solution.
