本論文主要目的為製備兩種兩性離子型的吸水性水膠，Poly(acryl amide-co- sulfobetaine) P(AM/SB) 和Poly(acryl amide-co- sulfobetaine)/ Slag) (P(AM/SB)/SG)，使用FT-IR作結構鑑定，探討單體比例、起始劑或交聯劑劑量、反應溫度和爐石含量對於水膠在各種水溶液下吸水率的影響。
將P(AM/SB)/SG水膠加到水泥漿和水泥砂漿中，作為自養護劑時，探討單體比例和爐石比例含量，對於水泥漿中水泥水化程度、圓盤裂縫和凝結時間的影響；以及對於水泥砂漿水份重量損失、抗壓強度、內部濕度和乾縮量的影響。
實驗結果顯示， P(AM/SB)水膠在純水中的最大吸水率為48.4 g/g，2.0M NaCl(aq) 和2.0M CaCl2(aq) 中的吸水率分別為55.7和61.2 g/g。
將P(AM/SB)/SG水膠加入水泥砂漿中，當水膠劑量為0.2 wt%，粒徑為0.082 mm，和爐石含量為15 wt%時，對水泥砂漿的重量損失、抗壓強度和內部濕度增加、乾縮量減少和水泥漿的圓盤裂縫減低有最佳的提升效果。

關鍵字：兩性離子型、水膠、合成、爐石、砂漿、吸水率、抗壓強度、內部濕度、乾縮。

This thesis has prepared two zwitterionic superabsorbent hydrogels, i.e., Poly(acrylamide-co-sulfobetaine) (P(AM/SB)) and Poly(acrylamide- co-sulfobetaine)/slag (P(AM/SB)/SG). FT-IR was used to identify the functional groups of the hydrogel. The effects of monomer ratio, initiator and crosslinker dosage, and slag content on the water absorbency of the resulted hydrogel in various aqueous solutions were studied and discussed.
P(AM/SB) hydrogel was added into cementitious materials. The effects of monomer ratio and Slag content on the weight loss, compressive strength, internal humidity and drying shrinkage in mortars, and the cracking index in cement pastes were determined and discussed.
The results indicated that the highest water absorbency of all tested hydrogels were 48.4, 49.3 and 53.9 g/g in water, 0.1M NaCl(aq) and 0.1M CaCl2(aq), repectively. P(AM/SB)/SG hydrogel with 0.2 wt% dosage, particle size of 0.082 mm and 15 wt% Slag showed the best performance in cementitious materials. Namely, this polymer could decrease the weight loss and drying shrinkage, and increase the compressive strength and internal humidity in mortars, and reduce the craking formation in cement pastes.

Keywords: zwitterionic, hydrogel, synthesis, slag, mortar, water absorbency, compressive strength, internal humidity, drying shrinkage.
