本論文之研究主題是經由使用溶膠-凝膠法製備二氧化矽的過程得到透明之塊材，而溶膠經過凝膠化、老化、乾燥等過程，可以得到透明之塊材。同時我們也將研究溶膠-凝膠法在混合複合材料中的應用，即是形成有機聚合物與無機玻璃的混合物。
在研究二氧化矽之透明塊材過程中，首先由製備流程的選擇找出透明的範圍，然後再由凝膠的過程中，研究觀察發現DCCA的添加物對凝膠的過程影響不大且容易製備不龜裂膠，體但是老化及乾燥的過程中所產生的化學變化卻影響轉化成玻璃的關鍵，其次觀察其乾燥過程中的變化，並找出製備不龜裂膠體的配方。可將所得之膠體在高溫下進行緻密化而得到透明的石英(SiO2)材質。在混合複合材料方面，我們將有機高分子加入無機材質中，加強無機材質的柔韌性，並研究此混合複合材料中的有機高分子與無機高分子的相互分佈關係。
