Preparation method for copper oxide nanowires

摘要

The disclosure provides a preparation method for copper oxide nanowires including following steps: step 01, a conductive layer as an electrode is prepared on a clean substrate, or a clean substrate with a conductive layer is provided directly. Step 02, copper powder is weighed up, and the copper powder is homogeneously mixed with organic carrier. Step 03, mixture prepared in step 02 is printed onto the clean substrate with a conductive layer. Step 04, the substrate after being processed by step 03 is sintered under atmosphere having oxygen, and finally cooled to obtain copper oxide nanowires. Adhesion between the copper oxide nanowires prepared in the present disclosure and the substrate is excellent, the copper oxide nanowires may substantially prepared uniformly in large area and under low temperature, technology flow of coating is decreased, a cost of manufacture is decreased, such that a promising method for bottleneck of commercialization process of the field emission device is provided.

1. A preparation method for copper oxide nanowires, comprising:
step 1, preparing a conductive layer as an electrode on a clean substrate, or directly providing a clean substrate with a conductive layer; step 2, weighing up a predetermined amount of copper powder, and homogeneously mixing the copper powder with a predetermined amount of organic carrier sufficient to result in a printable homogenous mixture; step 3, screen printing the homogenous mixture prepared in step 2 on the clean substrate with a conductive layer; and step 4, sintering the substrate after being processed by step 3 under atmosphere having oxygen to substantially oxidatively decompose the organic carrier to deposit the sintered copper in direct contact with the conductive layer devoid of an adhesive binding agent, and obtaining copper oxide nanowires after a cooling process.
