Oxide coatings, applications

More recently, alternative chemistries have been employed to coat oxide surfaces with SAMs. These have included carboxylic 1129, 1301, hydroxamic 11311, phosphonic 1124, 1321 and phosphoric acids 11331. Potential applications of SAMs on oxide surfaces range from protective coatings and adhesive layers to biosensors. 

Other substrates such as graphite powder and mica are also coated with nickel. Silver is the most conductive metal, being almost 5 times less resistant than nickel. Silver and copper have very similar conductivities but copper is easily oxidized and reacts with acids readily which affects its performance in polymeric systems. The PQ Corporation and Potters Industries, Inc. have developed a whole range of products which are silver coated. Their application is for conductive thermosets, gaskets, sealants, adhesives, paints, coatings, inks, and EMI control applications. Its use in these products saves 1/3 of weight of conductive material. 

Fatty acids can make pyrite highly hydrophobic, which may reduce flie contact of Fe with the surface (Nyavor et al. 1996). Nyavor et al. (19%) studied flie effectiveness of fatty acid in a laboratory experiment and found that it significantly inhibited both chemical and biological oxidation. Jiang et al. (2(XX)) used a mono-saturated fatty acid such as sodium oleate to create a hydrophobic layer on pyrite surfaces, but this coating resulted in incomplete oxidation. Application of this chemical on a field scale may not be feasible because it is toxic and costly (Wu et al. 2006).

Metal oxides are used as pigments, electrolytes, and coatings. Oxides are also intimately involved in the processes of corrosion, catalysis, energy production, and pollution control. There is therefore considerable incentive to understand oxide properties so that rational materials selection and process optimization may be undertaken. Attainment of these twin objectives increasingly entails realistic force field based atomic modeling. Applications of such methods to oxide systems are briefly reviewed. 

Nanowire arrays of a-CNT-coated single crystal and polyciys-talline Sn02 NWs can be easily fabricated by this method. They show great promise for application as anodes in LIBs for use in nanodevice power supply. In addition, other NW arrays of a-CNTs coated oxides can also be prepared by this process.

In addition to reflective or colored coatings, oxide coatings on glass and silicon substrates (single layers, multilayers, and porous layers) have been used extensively as antireflective (AR) surfaces in solar-related applications to improve device efficiency and as laser-damage-resistant AR coatings for laser optics, especially in inertial confinement fusion applications [25-37]. 

The presence of the unsaturated substituent along this polyester backbone gives this polymer crosslinking possibilities through a secondary reaction of the double bond. These polymers are used in paints, varnishes, and lacquers, where the ultimate cross-linked product results from the oxidation of the double bond as the coating cures. A cross-linked polyester could also result from reaction (5.J) without the unsaturated carboxylic acid, but the latter would produce a gel in which the entire reaction mass solidified and is not as well suited to coatings applications as the polymer that crosslinks upon drying. ... 

Another sol—gel abrasive, produced by seeding with a-ferric oxide or its precursors, has been patented (30). A magnesium-modified version of this abrasive, also called Cubitron, is being produced as a replacement for the earlier type. Yttria [1314-36-91-vnc>A V eA sol—gel abrasives have also been patented (31), as well as rare earth oxide modified materials (32). These abrasives are all produced by 3M Corporation they have performed very well ia various applications such as ia coated abrasives for grinding stainless steel and exotic alloys.
