Preparation method of patterned polyethylene 4-thiol nickel thin film and device

Abstract

The invention discloses a preparation method of a patterned polyethylene 4-thiol nickel thin film and device. The method comprises the following steps of (1) patterning a polymer coating on the surface of a substrate according to a predesigned pattern to obtain the substrate covered with a polymer template, and taking a blank part on the surface of the substrate as a designed pattern; and (2) carrying out stirring reaction on potassium methoxide and 1,3,4,6-tetrathia-cyclopentene-2,5-diketone into an organic solvent in an inert atmosphere, adding nickel chloride for reaction, carrying out filtration after reaction is completed, collecting filtrate, transferring the filtrate to an electrolytic tank, fixing the substrate covered with the polymer template on a working electrode, carrying out oxidizing coordination polymerization reaction by adopting a constant potential oxidation method and a three-electrode system, completely covering the polymer template and the surface of the blank part on the surface of the substrate with a polyethylene 4-thiol nickel thin film and removing the polymer coating to obtain the patterned polyethylene 4-thiol nickel thin film on the blank part. According to the method, the sizes, the quantity and the properties of patterning devices can be well controlled, the process is simple and the cost is low.

Description

technical field [0001] The invention belongs to the field of organic thermoelectric materials, and in particular relates to a patterned polyethylene tetrathiol nickel thin film and a preparation method of a device. Background technique [0002] As the largest carbon emitter, China will face a severe test in the future to achieve rapid economic growth and build a friendly environment. Research and development of emerging energy industries is also a top priority during the 13th Five-Year Plan period. As a kind of environment-friendly energy conversion materials, thermoelectric materials have gradually attracted people's attention. Seebeck effect, Peltier effect, and Thomson effect provide theoretical support for the application of thermoelectric materials. We can use thermoelectric materials to realize temperature difference power generation, and we can also make thermoelectric materials heat or cool under the drive of electric field; moreover, the refrigeration and power ge...

Problems solved by technology

However, the film has the characteristics of infusibility and insolubility, and the patterning process is difficult, and it is not easy to be etched by laser etching or plasma sputtering; the synthesis process requires more than ten hours of electrochemistry in a solvent, and it is not enough to simply clip a template on the substrate , the solvent will permeate in; only polymers are used as the template, because the surface is uneven, which hinders the growth of the film; the film and the substrate are firmly bonded, and it is not easy to use the engraving technology
