Abstract:
1. A method for combining a first material and a second material, comprising the steps of: (a) providing a first material, the first material being a functional material able to alter property of or impart a property to a second material; (b) providing a fluid which is near or in the supercritical fluid state, (c) at least partially dissolving the first functional material in the fluid, (d) providing a second material, the second material being a bulk, matrix material; (e) only subsequently incorporating the solution of the first functional material and the fluid into the bulk material to form a single phase solution from the first functional material, the bulk material and said fluid, and (f) removing said fluid from said solution in order to leave the combined first functional and bulk materials, thereby resulting in a material having the altered or imparted property of the functional material.
