| dc.description.abstract | 本論文使用單元小室模型分析於一無鹽懸浮液中，球形帶電軟質粒子(每個粒子中心為一球形固體硬核，於其表面吸附一層帶有固定電荷密度之多孔聚電解質)之電泳運動與懸浮液之電傳導。在一單元小室內，僅有一種異性離子存在於一帶電軟質粒子周圍之無鹽溶液中，藉由適用於此系統之線性化Poisson-Boltzmann方程式以及Laplace方程式分別求解平衡電位分布以及由外加電場所引起之擾動電位分布，並透過離子的連續方程式及修正後的Stokes方程式分別求得電化學位能分布以及流體流速分布。求解上述物理量分布後，再藉由力平衡以及平均電流密度即可獲得軟質粒子電泳可動度和懸浮液有效電導度的解析解公式，結果顯示粒子之間的交互作用對於電泳可動度與有效電導度有著顯著的影響。與電解質溶液懸浮系統相同，在無鹽溶液懸浮系統中於其他參數不變的情況下，電泳可動度會隨著粒子固定電荷密度的增加而增加，並隨著硬核與粒子半徑比、粒子半徑與多孔層滲透長度比、以及粒子體積分率的增加而下降。無鹽懸浮液之正規化有效電導度也會隨著固定電荷密度的增加及硬核與粒子半徑比的下降而增加，但是正規化有效電導度並不是粒子體積分率的單調函數。 | zh_TW |
