Patent ID: 8241417

Claim:
A nanocomposite coating, comprising: a nanometer inorganic oxide gel made by a sol-gel method and having 22.5˜49.5% weight in the nanocomposite coating; an organic solvent having 45˜74.25% weight in the nanocomposite coating; and a nanometer powder having 1˜10% weight in the nanocomposite coating; wherein the nanocomposite coating is formed by mixing the nanometer inorganic oxide gel, the organic solvent and the nanometer powder together; wherein the nanometer powder is processed by a surfactant before being mixed with the nanometer inorganic oxide gel and the organic solvent to form the nanocomposite coating; wherein the surfactant is any one of or a mixture of a sodium dodecylsulphonate and a polyvinyl pyrrolidone.
