  • 本篇論文主要是合成兩性離子型的水膠,poly(acrylamide-co-DAE) (PDAE),探討單體比例、起始劑、交聯劑與水解時間對PDAE水膠吸水率的影響,以及水膠在純水與鹽水中,在不同pH下的吸水率。並且評估PDAE水膠作為水泥砂漿自養護劑之可行性,即探討PDAE對水泥砂漿試體的保水率、內部相對溼度、抗壓強度之影響。合成之PDAE以FT-IR光譜確認其結構。
    研究結果顯示最佳反應條件為DAE:AAm = 4:6、APS = 1.3 mol%、MBA = 0.5 mol%,所製得之PDAE在純水中的吸水率可達400 g/g;在0.1M NaCl(aq)、0.1M CaCl2(aq)的吸水率分別為39.3、31.1 g/g。最佳水解時間為六小時,可使PDAE吸水率由400增加到713 g/g;在0.1M之NaCl(aq)的吸水率由39.3增加到78.2 g/g。
    以PDAE作為水泥砂漿之自養護劑,測試結果可知最佳添加量為0.14% ,所形成的水泥砂漿試體的保水率、內部相對溼度與控制組相比較均有提升,抗壓強度則略為下降。
