▎ 摘　　要

NOVELTY - Preparing nanoparticles on a substrate involves depositing micro-sized particles or salt precursors on a substrate, and applying a rapid, high temperature thermal shock to the substrate and the micro-sized particles or the salt precursors to cause the micro-sized particles or the salt precursors to become nanoparticles on the substrate. The micro-sized particles comprise aluminum, tin, gold, palladium, iron, nickel, or silicon. USE - Method for preparing nanoparticles on a substrate for composite (claimed). ADVANTAGE - The method includes depositing micro-sized particles or salt precursors on a substrate, and applying a rapid, high temperature thermal shock to the substrate and the micro-sized particles or the salt precursors to cause the micro-sized particles or the salt precursors to self-assemble into nanoparticles on the substrate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a system for synthesizing nanoparticles on a substrate, which includes a rotatable member configured to receive a roll of a substrate sheet having deposited thereon micro-sized particles or salt precursors, a motor configured to rotate the rotatable member to unroll consecutive portions of the substrate sheet from the roll, and a thermal energy source configured to apply a short, high temperature thermal shock to consecutive portions of the substrate sheet that are unrolled from the roll by rotating the rotatable member to cause the micro-sized particles or the salt precursors to become nanoparticles on consecutive portions of the substrate sheet; and 2. a composite comprises a substrate, and multiple of nanoparticles formed on the substrate from a micro-sized particle or salt precursors exposed to a rapid, high temperature thermal shock.
