摘要

本研究採用實驗設計法，設計出8組不同的方案，並且依其變色溫度實驗中找出液態水膠可變色的溫度範圍於27oc至32oc，變色時間於45秒至150秒。在相同的體積莫爾濃度下，控制不同之變因及製作出不同性質水膠，使其在照度上與變色溫度與變色時間不相同的特性。其中以方案3與方案8之兩組實驗為例，在方案3節能窗材變色溫度為27℃，變色時間在45秒內完成變色，於所有方案變色溫度中最低，變色時間最快，而方案8變色溫度為32℃，變色速度需150秒，於所有方案中變色溫度最高，變色時間最慢。但照度量測實驗中，方案3較不如方案8者可阻擋光線，其因是水膠結構之關係，於其他方案測試結果皆在方案3與方案8之間。長時間戶外量測中，結果顯示節能窗材能夠阻擋三分之一以上之熱能，相對照度也比一般透明玻璃抵擋九成以上的照度仍在實用範圍內，效果遠比一般玻璃來得有效。除此之外利用實驗所製作出8組方案可視所需條件，廣泛檢視節能窗材之應用。本研究歸納出熱致色變水膠應用於節能窗材，其效果符合節能減碳的環保需求。

Full Expermential is applied in this study factor the design . There are eight different design cases are carrived for finding lower critical solution temperature. According to the lower critical solution temperature by experiment for hydrogel be found that solution temperature range is from 27℃to 32℃ and as well as specific the time for color change is from 45 to 150 seconds. The character is this of hydrogel the illumination lower critical solution temperature and change color time with different characteristic. It is found that low critical solution temperature of case3 is 27℃, control changing time is 45 seconds. It shows that these data is not only the lowest control solution temperature but also the fastest control changing time.
Control changing temperature is 32℃ . color changing time is 150 seconds for case8 material .It is found that the control changing temperature is the highest but also the control changing time is the lowest .
According to illumination measurements materials of case3 gets less block eight.Performance than that of case8 material.
