本研究利用溶凝膠能在常溫下合成的特性，將固體模板PS小球加入溶凝膠液中，之後再以溶劑氯仿溶出，來獲得所需的孔洞。並根據溶凝膠之性質，改變不同的酸鹼值與靜置時間(aging time)，得到不同黏度的溶液，藉以製備出不同厚度的薄膜。從實驗得知，pH值與靜置天數的增加會使溶液黏度變大，進而膜厚也會增加，而欲獲得一良好且孔洞均勻分散的薄膜，pH值需控制在4以下，靜置天數需小於5天。而針對溶液黏度來看，黏度值需控制在6c.p.以下，所得之薄膜均勻性較佳。再將所得之膜厚實驗值與文獻中經驗方程式求得的理論值相比較，發現溶液中水為溶劑的主要成份，而乙醇所佔的含量較少。
此外，也針對薄膜厚度的改變是否會對孔洞深度造成影響進行探討，由實驗結果發現由於模板密度小於溶凝膠液密度，模板位置為浮在薄膜上面，因此膜厚的增加並不會使模板包埋的體積增加，而模板移除後孔洞深度也未隨膜厚增加而加深。接著，本研究嘗試利用多層覆蓋(multi-layer coating)的方式來增加模板的包埋深度。由AFM照片得知，當所鍍膜層增加時，孔洞深度及孔徑大小皆會隨之增大。但由於附著力的關係，鍍膜層數過多時，脫落情形嚴重，因此膜數需保持在兩層以下。

The research according to the characteristics of sol-gel of reaction at general temperature, put solid template in sol-gel solution and then removed with chloroform to get the porous. The research also changed pH value and aging time to get solution with different viscosity, and then prepared film with different thickness. From the results we know that the more pH value and aging time , the larger viscosity and film thickness. We also know that we can get a nice film under pH=4 and five days. If the viscosity of solution is under 6c.p., we can also get a nice film. Comparing with the experimental value of film thickness and the theoretical value of film thickness, we found that solvent contains much water and less alcohol.
The other part of the research is to know if the change of film thickness would effect the porous depth. From the results we found the position of template is on the film because of density, and the change of film thickness would not effect the porous depth. Then we increase the embedded volume of template with multi-layer coating. According to AFM pictures we know the porous depth is longer when the coating layer is increasing. But because of adhesion force, film will fall off as the layer film is too much.
