Abstract
The diameters of Dow latex particles in the size range from 0.085 to 0.330 μm were determined by electron microscopy. The effects of electron irradiation and the vacuum conditions in the microscope on the measured particle diameter were investigated. A comparison among latex samples was also made. The results confirmed that the measured diameters did not agree with the nominal diameters determined by the manufacturer of the latex particles. Differences lay in the range from + 6 to −18%. Standard deviations of the size distributions were also found to be different from the nominal values. Therefore, for accurate experiments, it is necessary to confirm the size of latex particles.
