Abstract: A functionalized inorganic filler includes a dendritic fibrous nanoparticle that has a surface functionality including at least one amine functional group linked to a surface of the dendritic fibrous nanoparticle. A method of making a functionalized inorganic filler includes reacting an inorganic particle precursor and a shape-directing agent to provide a dendritic fibrous nanoparticle, then reacting the dendritic fibrous nanoparticle with a reactive compound that has at least one amine functional group to form the functionalized inorganic filler. A polymer composite includes an epoxy-based polymer matrix and a functionalized inorganic filler.

Abstract: A method of fabricating a hydrophobic coating on a surface of a solid substrate which includes a layer-integrable material includes the steps of depositing a deformable layer of the layer-integrable material onto the surface of the solid substrate, forcibly embedding a plurality of particles within the deformable layer, and solidifying the deformable layer including the plurality of particles so as to be integral with the surface of the solid substrate. At least a portion of the plurality of particles is embedded at a threshold depth within the deformable layer prior to solidification.

Abstract: A polymer composite formed from an epoxy based polymer and an amino-graphene. The epoxy based polymer forms a polymer matrix and the amino graphene is dispersed throughout the polymer matrix. Further, a graphene is functionalized with 3,5-dinitrophenyl groups to form functionalized graphene and one or more amine functional groups form Meisenheimer complexes with the functionalized graphene to form the amino-graphene. An associated method of making the polymer composite is also provided.
