PURPOSE: A method for preparing metal nano particle colloid solution is provided to easily prepare the solution and ensure long-term preservation with stability. CONSTITUTION: A method for preparing metal nano particle colloid solution comprises: a first step of adding metal precursor, polymer, and dispersing agent to solvent and stirring at 25-85°C for 1 to 20 hours to obtain mixture solution; a second step of treating mixture solution with first ultrasonic wave; a third step of depositing the mixture solution and removing precipitate; a step of treating mixture solution with a second ultrasonic wave for 2 to 20 hours; and a step of adding reductant to the mixture solution to reduce the solution. |
