  • Patent number: 8226761
    Abstract: A method of modifying a pigment that includes reacting a reactive compound having an X—[Y]n reactive group with a secondary compound N—S—ZM to form a substituted reactive intermediate [Y]a—X—(N—S—ZM)b. A pigment is reacted with the substituted reactive intermediate [Y]a—X—(N—S—ZM)b to attach the substituted reactive intermediate to the surface of the pigment to form a surface modified pigment. X may be a sulfonyl, phosphoryl, or 1,3,5-triazinyl group, Y may be a halogen leaving group, N may be a basic nucleophilic group, S may be an organic group, and ZM may be an ionizable end group. Also, n is an integer between 1 and 3, b is an integer between 1 and 3, and a=n?b. When n is equal to or greater than b, and if b is 2 or 3, each N—S—ZM can be the same or different.

  • Patent number: 8221834
    Abstract: A titania composite and a preparing method thereof are provided. The titania composite comprises an inner core and a coating film layer, wherein the inner core is a barium sulfate crystal and/or a strontitum sulfate crystal with subsphaeroidal shape, having a particle size of less than 1 ?m and whiteness of more than 98%, and the coating film layer is nano rutile titania. The preparing method thereof comprises the following steps: (a) preparing barium sulfate or strontium sulfate; (b) coating treatment; (c) subjecting the titania composite to a high-temperature heat treatment; and (d) subjecting the titania composite to a post treatment. The subsphaeroidal titania composite is obtained by chemically synthesizing a subsphaeroidal submicron barium sulfide or strontium sulfide, and then hydrolyzing and coating thereon to form a coating film layer of titania to make titania grow evenly.

    Abstract: CIGS absorber layers fabricated using coated semiconducting nanoparticles and/or quantum dots are disclosed. Core nanoparticles and/or quantum dots containing one or more elements from group IB and/or IIIA and/or VIA may be coated with one or more layers containing elements group IB, IIIA or VIA. Using nanoparticles with a defined surface area, a layer thickness could be tuned to give the proper stoichiometric ratio, and/or crystal phase, and/or size, and/or shape. The coated nanoparticles could then be placed in a dispersant for use as an ink, paste, or paint. By appropriate coating of the core nanoparticles, the resulting coated nanoparticles can have the desired elements intermixed within the size scale of the nanoparticle, while the phase can be controlled by tuning the stochiometry, and the stoichiometry of the coated nanoparticle may be tuned by controlling the thickness of the coating(s).
