A METHOD FOR LOW-COST PREPARATION OF 1BIT OR 2BIT RF TAG USING PRINTING PROCESS

摘要

A method for manufacturing very low priced 1 or 2 bit RF tags by using a printing process is provided to print an LC resonance circuit on a plastic film by using electronic ink with high conductivity and to manufacture the 1 or 2 bit RF tags with various frequency ranges by controlling easily resonance frequencies. A method for manufacturing very low priced 1 or 2 bit RF tags by using a printing process comprises the following several steps. A solution including 1-100ppm platinum group halide in alkylene glycol is produced. An alkylene glycol solution including 0.1-10 weight % Ag precursor is produced in another vessel, and an alkylene glycol solution including 0.1-2 weight % polyaniline is produced in another vessel. The produced solutions are mixed. The mixed solution is heated at 100-200 degrees for 1-10 hours, alkythiophene is added to the mixed solution with volume ratio of 100 to 0.01-0.2, and the added solution is cooled. Precipitation is processed by using non-solvate like acetone and centrifugal separation is processed. Washing is processed by using a mixed solvate made of acetone and water, centrifugal separation processes are performed, and finally a nano sized metal wire is produced.
