在現今工業上，多相塗佈製程已是不可或缺的重要製程之一，本研究以淋幕式塗佈為實驗系統探討微粒子添加入甘油水溶液後，塗佈行為的變化，並研究雙層淋幕式塗佈在不同參數下塗佈之行為。單層淋幕式塗佈實驗結果顯示，添加微粒子於甘油水溶液中，可以有助於降低最小成膜流量和穩定動態濕潤線，抑制空氣滲入，提高最大塗佈速度，且粒子濃度越高，粒徑越小延後空氣滲入的效果越好。雙層淋幕式塗佈實驗發現，透過攜帶層的幫助，可以提高上層塗液的最大塗佈速度，且攜帶層中粒子的含量越高，越有助於提升上層塗液的最大塗佈速度，再透過改變上下層的黏度比以及攜帶層的流量等參數，發現改變攜帶層的流量對上層塗液的最大塗佈速度並不會造成影響，而利用較低黏度的攜帶層則會有助於提升上層的最大塗佈速度，且上下層間的黏度會存在一最佳黏度比，如果上下層黏度相差太大，則會造成淋幕的不穩。
