摘要

奈米技術發展數十年，各式各樣的奈米材料已被發現或製備，為了應用這些奈米材料，分散技術是關鍵點。在文獻中已提出各種化學或物理的分散方法，然而，這些技術仍無法配合分散和應用間的需求。因此，我們建立了一個新式的分散系統－幾何形態分散，其分散概念為利用材料在幾何形態上的高度差異性，可提升材料的分散性。在本研究中，各種奈米材料(奈米碳管、奈米碳球、奈米炭黑、
奈米銀粒子、奈米鐵粒子)、疏水性共軛高分子和有機顏料被用來應證“幾何形態影響分散”之通則性。

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.
