Abstract
Evaluation of aggregation and agglomeration of carbon nanotube (CNT) solution has been one of the key issues for applications. Here we introduce a simple method based on depolarized dynamic light scattering (DDLS) performed at multiple scattering angles to characterize the size and morphology by monitoring the rotational diffusion and the translational diffusion, and compared results with the statistics obtained by transmission electron microscope (TEM) image analysis. We examined three types of multiwall carbon nanotube; MWCNT made by arc-discharge method and the chemical vapor deposition (CVD) methods. It was found that we can easily estimate the shape, aspect ratio, and size of dispersed CNT by DDLS method, and that the results were almost consistent with the TEM image analysis.Proceedings Title
