    Abstract: PURPOSE: A manufacturing method of copper nanoparticles and a manufacturing method of triazole compound which uses thereof as a catalyst are provided to synthesize water-soluble copper nanoparticles which is stable under a mild processing condition. CONSTITUTION: A manufacturing method of copper nanoparticles uses double block hydrophilic copolymers(10). The double block hydrophilic copolymer consists of active ionization blocks(11) and neutral blocks(12). The double block hydrophilic copolymer is poly(acrylic acid)-b-poly(ethylene oxide)(PAA-b-PEO). A manufacturing method of the copper nanoparticle comprises the following steps: manufacturing a mixture by stirring the double block hydrophilic copolymer and copper chloridation dihydrate; producing suspension by adding NaOH in the mixture; and adding hydrazine to the suspension while strongly stirring the mixture.
