Some laser applications produce high power densities that can be dangerous to equipment and operators. We have fabricated thin-film coatings by using molecular electrostatic self-assembly to create a spectrally selective absorbing coating that is able to withstand thermal fluctuations from -20 degrees C to 120 degrees C. We made the thin-film coatings by alternating deposition of an organic dye...

Composite materials can be prepared by the combination of at least two different phases, a continuous and a dispersed one. If one of these phases is on the nanometer scale, than the material is called a nanocomposite. In this context organic-inorganic hybrids stand for a new class of materials formed by two distinct compounds, the polymeric and ceramic, resulting in a crosslinked amorphous nano...

Arrays with polymer-coated acoustic sensors, such as surface acoustic wave (SAW) and surface transverse wave (STW) sensors, have successfully been applied for a variety of gas sensing applications. However, the stability of the sensors' polymer coatings over a longer period of use has hardly been investigated. We used an array of eight STW resonator sensors coated with different polymers. This ...

Organic coatings act as a barrier to a corrosive solution and check the transfer of electrical charge from the corrosive solution. High performance organic paint systems were applied on plain carbon steel substrate with two different primers viz., epoxy Zn phosphate and epoxy Zn rich. Identical intermediate and top coats were applied on them having equal dry film thickness. Both uncontrolled lo...

Polymethylmethacrylate (PMMA) is a material of choice for many biomedical coating applications. However, such applications are limited due to the toxicity traditional solvents used solution processing PMMA coatings and composites. This problem addressed using an isopropanol-water co-solvent, which allows dissolution high molecular mass fabrication by dip-coating method from concentrated solutio...

ni-p and ni layers multilayer coatings were applied to az31 magnesium alloy utilizing electroless and electrodeposition procedures. the aim of the project was to decrease cracks and increase corrosion resistance of the coatings. in order to compare the coatings, the effect of single layer electroless ni-p coatings with different thicknesses was also investigated. the microstructure and phase co...
