摘要:
A method of forming a microplasma device places a curable polymer material between a mold having a negative volume impression of microcavities and/or microchannels and a substrate. The polymer is cured and then the mold is separated from the solid polymer. The method can form a microplasma device that includes a substrate and either or both of a microchannel or microcavity defined in a polymer layer supported by the substrate. Electrodes arranged with respect to the polymer material can excite plasma in a discharge medium contained in the microchannel or the microcavity or both. A flexible mold is preferably used to fabricate transparent polymer microcavities onto rigid substrates. A rigid mold is preferably used to fabricate transparent polymer microcavities onto flexible substrates. Having one of the mold and the substrate flexible and the other rigid aids in the separation of the mold from the cured polymer.
摘要:
A gas reactor device includes a plurality of microcavities or microchannels defined at least partially within a thick metal oxide layer consisting essentially of defect free oxide. Electrodes are arranged with respect to the microcavities or microchannels to stimulate plasma generation therein upon application of suitable voltage. One or more or all of the electrodes are encapsulated within the thick metal oxide layer. A gas inlet is configured to receive feedstock gas into the plurality of microcavities or microchannels. An outlet is configured to outlet reactor product from the plurality of microcavities or microchannels. In an example preferred device, the feedstock gas is air or O2 and is converted by the plasma into ozone (O3). In another preferred device, the feedstock gas is an unwanted gas to be decomposed into a desired form. Gas reactor devices of the invention can, for example, decompose gases such as CO2, CH4, or NOx.
