Patent ID: 7923068

Claim:
A method of producing a composite film, comprising: (a) placing a cluster of particles into a reaction space, the cluster defining inter-particulate spaces in fluid communication with the reaction space; (b) introducing a first precursor chemical into the reaction space so that the first precursor chemical infiltrates the inter-particulate spaces and adsorbs to surfaces of the particles bordering the inter-particulate spaces; (c) after step (b), purging the reaction space until excess non-adsorbed amounts of the first precursor chemical are substantially removed from the reaction space, but non-adsorbed residual amounts of the first precursor chemical remain within the inter-particulate spaces; (d) after step (c), introducing a second precursor chemical into the reaction space, wherein the second precursor chemical infiltrates the inter-particulate spaces and reacts with the first precursor chemical, including reacting with the non-adsorbed residual first precursor chemical, to form a deposit of filler material on the surfaces of the particles and in the inter-particulate spaces; (e) removing excess amounts of the second precursor chemical from the reaction space; and (f) repeating the steps (b) through (e) until the particles are embedded in the filler material.
