Abstract: The effect of agitation speed and temperature on the formation of silver nanoparticles (AgNPs) in waterborne polyurethane (WPU) was investigated. UV-Vis spectrophotometer and transmission electron microscope (TEM) were used to determine the formation of AgNPs. The size of silver nanoparticles could be controlled by changing the reaction conditions. The increase in agitation speed and temperature during the in situ reduction of silver ions in WPU resulted in higher population of silver nanoparticles in WPU films. The results obtained from UV-Vis spectrophotometer showed peak shifts toward shorter wavelength, which indicated that the size of AgNPs decreased. TEM images reviewed that silver nanoparticles had a spherical shape with particle size less than 20 nm and good dispersion in WPU matrix as agitation speed and temperature increased
