此研究討論以高分子相分離製備出具表面孔洞的高分子薄膜，使具備抗反射功能；在文獻中我們看過許多製作抗眩、抗反射膜的方法，除了主要的高分子相分離外, 還包括奈米粒子塗佈、濺鍍(sputtering)以及溶膠-凝膠(sol-gel)等製作多層結構的方法。
在我們的研究當中，我們利用浸沾式塗佈的方法，製造出各種不同的高分子薄膜。浸沾式塗佈可省去較多的材料成本，不需像旋轉塗佈一樣將多餘的材料甩掉；且浸沾式塗佈的設備較為簡單，只需將欲塗佈的物品夾住，進入溶液中再拉起即可，如此一來即使是非平板的物件也可以用此方法塗佈，又可以同一製程時間形成雙面塗佈。我們認為浸沾式塗佈是一種很有潛力的作法。
在製造表面孔洞高分子薄膜上，我們使用聚氯乙烯（polystyrene，PS）和聚乙烯吡咯烷酮（poly(vinyl pyrrolidone)，PVP）兩種高分子，分子量分別為250,000以及58,000，溶劑為氯仿(chloroform)；利用PS以及PVP兩高分子的特性，PS為疏水性高分子，而PVP為親水性高分子，當PS/PVP/chloroform混合溶液利用浸沾式製程形成薄膜時，在乾燥過程中，兩高分子會相分離形成表面孔洞薄膜。
我們所使用的PS/PVP的重量比為7比3，濃度範圍落在0.3wt%~5wt%，浸沾式塗佈的拉速範圍則落在6cm/min~75cm/min；經由濃度與拉速的改變，可以得到不同孔洞結構的高分子膜,我們量測其孔深、厚度以及平均孔徑，而這些形貌特性的不同，使高分子膜的穿透度以及反射率有所差異。
在濃度為0.6wt%、拉速為19cm/min時，相較於空白玻璃基板本身的穿透度為90%~91%，我們得到最佳穿透度為94%，其平均孔徑為156nm，厚度落在125nm，孔深為20nm；經由乙醇將PVP蝕刻後，穿透度可再上升至94.5~95%，此時孔深約37nm。

This research discusses preparation of antireflection (AR) optical film, which may be used on liquid crystal displays. There have been reported a lot of different methods to make antiglare and AR films, such as phase separation, sol-gel, sputtering, and nano-particle coating.
In our research, we prepared different kinds of porous polymer-films by dip coating processes. Dip coating processes possess many advantages. It makes efficient use of the processing materials and requires simpler set-up. All one has to do is clip the sample, put it into the coating solution, and pull it out. Dip coating can obtain double side coating at once. Most importantly, it can be applied to curved objects with complicated shape.
In this thesis, hydrophobic PS and hydrophilic PVP are used to form AR films possessing of surface pores through the phase separation mechanism. After getting the porous films, I observe their film morphologies and measure their transmittances. The optimal processing conditions found are coating speed of 19 cm/min and coating solution concentration of 0.6wt%. An improvement of 3% transmittance is achieved as compared to bare glass. After removing the PVP phase from the film with ethanol etching, the film performance can be improved even further by about 1% transmittance.
