Carbon nanotube (CNT) is a promising material that enhances the characteristics of plastic, because of this, its production volume is increasing. To evaluate CNT exposure in the workplace by carbon analysis, the size distribution of CNT aerosols is a key factor in separating CNT aerosols from ambient small particles. In this study, the mass size distributions of the simulated CNT aerosols were measured for samples collected using a Sioutas cascade impactor. Both monomodal and bimodal distributions were observed. Thinner CNTs tended to show monomodal distribution in the scanning electron microscopic observations because they contained strong agglomerates of tangled fiber.
