臺灣博碩士論文加值系統

利用黏度計量測流體在靜止狀態下的黏度了解其基本性質後，透過流動光散射分析流場下高分子的動態結構變化。我們自行設計黏度恆溫水槽，能有效控制黏度量測的溫控系統；加入光纖端子及XY微調器等加強流動光散射系統的微調功能。本研究首先測量黏度以判斷此黏度量測系統的準確度，接著藉由本質黏度得到臨界濃度，確保其為稀薄溶液後再利用流動光散射作後續分析。流動光散射方面，使用甲苯和鄰–苯二甲酸二（2–乙基己基）酯（DOP）的靜態光散射 分析，以及動態光散射測量已知粒徑之聚苯乙烯膠體粒子，對流動光散射系統的散射角度作校正。最後透過光學軟體模擬流場下的理想裝置及選定溶液的剪切速率範圍，初步進行流場下的實驗。

The orientation and deformation of polymer chains in dilute solution were measured by flow light scattering （FLS） techniques. The dilute solution range was examined using the intrinsic viscosity data. In this study, we constructed a home-made viscosity measuring system and modified the existing FLS system. The intrinsic viscosity results agree well with those obtained by the Mark-Houwink equation. The FLS system has been tested using colloidal particles with known size, and calibrated to reflect the angular dependence of the scattered light intensity.
