碩士 === 國立高雄大學 === 應用化學系碩士班 === 101 === The present study intends to one step hydrothermal synthesis method, a dense and continuous hydrotalcite (Layered Double Hydroxide, LDH) alkaline material film was prepared on an aluminum plate. Hydrotalcite is a layered inorganic material, has high-temperature characteristics, the interlayer can be further polymer modified, the formation of inorganic/organic nanocomposite materials, by using polymercharacteristics of non-conductive and more preventing an acid and alkalianto perform plug hole, hopecan segregate the water and other corrosive factors penetrate hydrotalcite to enhance corrosion resistance. First use hydrothermal Synthesis of hydrotalcitefilm, and use electrochemical to perform corrosion tests in different pH environment. Then use anionic surfactants at the membrane to improve interlayer distance and placed into polymer monomer to heat polymerization methodto form a composite material, identified by XRD, FTIR and SEM analysis, and use of the TGA test the thermal properties, observe the the polymer pyrolysis temperature can be improved under the hydrotalciteprotection, the ultimate the way byelectrochemical in an alkaline environment for corrosion tests, and compared with the before modifiedhydrotalcite performance .
