Abstract: Graphene-modified polymeric foam materials are provided that are amenable to conventional foams to yield articles with superior properties relative to like articles absent the graphene cell modifier. Graphene-based cell modifiers are incorporated in the polymer before or during the foaming process to not only improve the mechanical, thermal, electrical, fire retardant, or barrier properties of the polymer matrix itself, but also help modify the size, density, and morphology of cells in the foam, thereby tailoring the properties of the final foam articles. The graphene-modified polymeric foam materials may be utilized for the manufacturing of articles for mechanical, thermal, noise reduction, or sound absorption applications. The graphene-modified foams and articles made thereof have the advantages higher mechanical strength, better thermal stability, and better sound absorption properties as compared to the conventional polymeric foams such as materials made by copolymer polyol.

For such a purpose, the graphene has a high aspect ratio and good structural integrity, especially a lack of defects on the basal plane of the graphene.

Abstract: A composite material having utility for removing sulfur from a feedstock comprises a ceramic matrix having a relatively low melting point metal such as tin, zinc, lead or bismuth nanodispersed therein. The material may be prepared from a mixture of particles of a precursor of the ceramic matrix and precursor of the metal. The precursors are selected such that the melting point of the precursor of the ceramic is less than the melting point of the precursor of the metal. The mixture of precursor materials is heated to a temperature sufficient to melt the precursor of the ceramic material so as to coat it onto the precursor of the metal. The ceramic precursor is then reacted so as to convert it to a ceramic. Thereafter, the precursor of the metal is converted to a free metal which is retained within the ceramic matrix so as to prevent agglomeration.
