Claims38
A process of dry milling particulate materials, wherein at least one of the particulate materials is a layered material, in the presence of a non-layered material, to obtain a composition wherein said layered material is exfoliated and wherein the non-layered material is composited with the exfoliated material, the exfoliated material having a particle size of 10 microns by 5 nm thick, or less, and wherein the dry milling is controlled by controlling the surface energy of the milling media in addition to controlling the hardness of the milling media using plastic milling media.
An electrode produced from the product as claimed in claim 38.
A catalyst produced from the product as claimed in claim 39.
A coating produced from the product as claimed in claim 38.
An electronic component manufactured from the product as claimed in claim 38.
A thermally conductive component manufactured from the product as claimed in claim 38.
A process of dry milling particulate materials, wherein at least one of the particulate materials is a layered material, in the presence of a particulate material selected from the group consisting of i. ceramic, ii. glass, and iii. quartz, to obtain a composition wherein the layered material is exfoliated and wherein the particulate material is coated with the exfoliated material, the exfoliated material having a particle size of 500 nanometers or less, and wherein the dry milling is controlled by controlling the surface energy of the milling media in addition to controlling the hardness of the milling media using plastic milling media.
A process of dry milling particulate materials, wherein at least one of the particulate materials is a layered material, in the presence of a particulate material selected from the group consisting of i. ceramic, ii. glass, and iii. quartz, to obtain a composition wherein the layered material is exfoliated and wherein the particulate material is coated with the exfoliated material, the exfoliated material having a particle size of 10 microns or more, and the wherein the dry milling is controlled by controlling the surface energy of the milling media in addition to controlling the hardness of the milling media using plastic milling media.
A battery comprising at least one electrode as claimed in claim 38.
A capacitor comprising an electrode as claimed in claim 38.
A product when produced by a process of dry milling particulate materials, wherein at least one of the particulate materials is a layered material, in the presence of a non-layered material, to obtain a composition wherein said layered material is exfoliated and wherein said non-layered material is composited with said exfoliated material, said exfoliated material having a particle size of 10 microns by 5 nm thick, or less, wherein the exfoliated material has an aspect ratio of from 5 to 200, and wherein said dry milling is controlled by controlling the surface energy of said milling media in addition to controlling the hardness of said milling media using plastic milling media, said hardness being in the range of 3 to 100 on the Brinell Scale.
