General description

Please follow this link for Aedotron/Oligotron selection guide table.

Application

Nitromethane dispersions can be used to cast thin films on glass, ITO, silicon wafers and many polymeric substrates. Compatibility of the polymeric substrate with nitromethane should be tested in each case. Coat the substrate with a "pool" of the nitromethane dispersion. Thin transparent films are typically spun at 1000 RPM or higher speeds, but more conducting films can be obtained at lower speeds. A single layer spun at 1000 RPM is typically 75 nm thick.
Conducting polymer. Useful as anti-static layers, hole-transport layers in OLED′s and various organic electronics applications (flexible circuits, capacitors, batteries).

Caution

Store this product at room temperature (do not refrigerate or freeze). Some settling will normally occur. Agitate, sonicate, and filter prior to use. A plug of glass wool in a pipette can be used for easy filtration. The shelf life of this product will vary depending on how it is stored and handled. Product should be discarded if heavy aggregation occurs, or if sonication / filtering are inadequate to produce a good casting solution.
