博士 === 國立臺灣大學 === 高分子科學與工程學研究所 === 99 === Nanotechnology has been developed for decades and various nanomaterials were created and discovered. To apply these nanomaterials in advanced applications, dispersion techniques are the key issue for utilizing the novel nanomaterials. In the literatures, a variety of dispersion methods involving chemical and physical approaches were proposed. However, these techniques are still not meeting the requirements for the applications. Therefore, we established a new dispersion method based on the concept of using the distinct difference of geometric shapes of nanomaterials namely, “Geometric-Shape Inhomogeneity Factor” (GIF) for Dispersion. Various nanomaterials, including carbon nanotubes, carbon blacks, carbon nanocapsules, silver nanoparticles, iron-oxide nanoparticles, hydrophobic conjugated polymers and organic pigments were selected to generalize the GIF. All practical applications have been successfully improved on utilizing GIF for dispersing nanomaterials.
