Applications of Hydrophobic OrganicInorganic Nanohybrids

WithChang-Sik Ha, Saravanan Nagappan

This chapter provides some of the important applications of hydrophobic organic-inorganic nanohybrid materials. Oil spills are major environmental pollution events caused by the leakage of oil from oil-developing operations, accidents during the transportation of oil by ships, and other sources of oil leakage in the sea. The hydrophobic magnetic nanoparticles were spread over the oil-in water surface and were actuated magnetically. Hydrophobic organic-inorganic nanohybrids exhibit excellent surface hydrophobicity, such as good chemical and thermal stability, mechanical stability, transparency, scratch resistance, and water repellence. Several inorganic materials show photocatalytic activity under UV light or sunlight. Corrosion is a major environment problem on many substrates due to the erosion of the substrate under a range of conditions. Corrosion can occur by either chemical or electrochemical reactions and destroy the substrate by oxidation, hydroxylation, and formation of sulfide on the substrate. Corrosion also occurs on ceramics or polymer substrates by degradation.
