In this study, we investigated size and dispersibility in synthesized process of silver nanoparticles using PAA, and examined the optimal conditions to minimize silver nanoparticles. Concentration of silver nitrate aqueous solution, amount of PAA, organic solvent(acetone-ethanol), reducing agent were studied as experimental variables. At 0.05 M, many silver nanoparticles were produced and at 0.03 M was Confirmed smaller size(18.70-28.59 nm) of sphere shape than 0.05 M. We experimented equivalent ratios(R=) of 0.07 and 0.14 in the amount of PAA added respectively. At equivalent ratios of 0.07, particles are produced much more than 0.14 and particle size was smaller. When addition of Acetone -Ethanol(1:1) as organic solvents, size of silver nanoparticles was 28.10-36.43 nm. Silver nanoparticles produced by the addition of hydrazine were smaller than when not added. |
