由於目前對於塗佈行為的研究大都著重在單相溶液,而實際上工業界產品所使用的塗液大多為多相的懸浮液系統,因此本研究將以甘油水溶液作為主要塗液,藉由添加微粒至塗液中研究其效應,本實驗塗液系統是將不同粒徑的聚甲基丙烯酸甲酯 (PMMA) 粒子良好分散在甘油水溶液內,使其與甘油形成分散良好的懸浮液,而本實驗所使用模具分成兩大部份,第一部分利用狹縫式塗佈進行懸浮微粒塗液對其塗佈行為影響的研究,發現添加微粒有助於穩定其動態潤濕線,因而延後空氣滲入的現象,有效地提升最大塗佈速度並擴大塗佈視窗,且隨著粒子數量密度的上升,最大塗佈速度也隨之提高,而其中以小粒徑的微粒效果較佳。第二部份則進行添加微粒對淋幕式塗佈行為的影響,實驗發現添加微粒後,塗佈視窗有顯著地擴大,不僅有效提高最大塗佈速度,且有助降低最小成膜流量,增加淋幕穩定性。在相同粒徑下,其存在一最適化的粒子濃度,但仍以高粒子數量密度效果較佳,上述的研究動機均希望對於最大塗佈速度能有所提升,以利其工業化的最終目標。
