- Production method of silver particles and carbon nano material composite using Couette-Taylor reactor

摘要

The present invention comprises: an outer cylinder, an inner cylinder installed along the same axis as the outer cylinder, and a motor for rotationally driving the inner cylinder; In the method for producing a silver particle and carbon nanomaterial composite using a Couette-Taylor reactor including an inlet and an outlet connected to the external cylinder, the carbon nanomaterial is surface-modified to introduce a functional group into the conductive carbon nanomaterial. making; introducing a functional group capable of reacting with a silver salt precursor into the carbon nanomaterial by mixing the surface-modified carbon nanomaterial with an isocyanate-based compound and a pyrimidine-based compound; injecting the carbon nanomaterial into which the functional group is introduced together with a solvent into the inlet of the Couet-Taylor reactor; injecting the silver salt precursor together with a solvent into the inlet at a constant speed while rotating the inner cylinder; Injecting a reducing agent into the inlet at a constant speed, and forming a Kuwet-Taylor flow through the rotational driving of the inner cylinder to form silver particles of a uniform diameter. Thereby, it is possible to obtain the effect that the carbon nanomaterial, the silver precursor, and the reducing agent are synthesized into silver particles having a uniform diameter by the Kuett-Taylor flow.
