Patent ID: 7776604

Claim:
A method of forming a composition comprising a candidate particulate material and a matrix, wherein the method comprises providing one or more candidate particulate material selected from carbon black or silica for said matrix; said candidate particulate material having at least one morphological value of the candidate particulate material selected from the group consisting of shape, size, and structure or having at least one chemical value of the candidate particulate material selected from at least one of the group consisting of overall composition, surface composition, and extractable materials, and measuring (a) at least one homogenous interaction parameter for at least one candidate particulate material, wherein said homogeneous interaction parameter relates to how the candidate particulate material interacts with itself, and/or (b) at least one heterogeneous interaction parameter for at least one candidate particulate material and the matrix, wherein said heterogeneous interaction parameter relates to how the particulate material and the matrix interact with each other; adding at least one of said candidate particulate material to said matrix based upon the relationship of: A) at least one performance property of the composition and B) 1) said at least one homogeneous interaction parameter for each candidate particulate material, or B) 2) said at least one homogeneous interaction parameter for each candidate particulate material and at least one heterogeneous interaction parameter for each candidate particulate material and the matrix, and wherein said candidate particulate material and matrix once combined, form a composition that is within a specified performance property based at least in part on i) said homogenous and/or heterogeneous interaction parameter and ii) said morphological value or chemical value.
