    • 論文主要目的為製備兩種兩性離子型的水膠P(AM/SB) 和(P(AM/SB)/MMT)係使用丙烯醯胺、甲基丙烯酸二甲基丙基磺酸胺乙酯 (SB)和蒙托土為單體，經自由基反應合成，利用FT-IR作水膠結構鑑定，探討單體比例和蒙托土含量對於水膠在各種水溶液下吸水率的影響。
    將P(AM/SB)/MMT水膠加到水泥漿和水泥砂漿中，作為自養護劑時，探討單體比例和蒙托土比例含量，對於水泥漿中水泥水化程度、圓盤裂縫和凝結時間的影響；以及對於水泥砂漿抗壓強度、內部濕度、乾縮量和自收縮量的影響。
    研究結果顯示， P(AM/SB)/MMT水膠：當AM/SB= 8, APS= 0.5 mol%, MBA= 2.0 mol%, MMT = 10 wt%時，在純水中和Pore solution中的最大吸水率分別為28.3 g/g和54.0 g/g。
    將P(AM/SB)/MMT水膠加入水泥砂漿中，當水膠劑量為0.2 wt%，粒徑為0.082 mm， 和蒙托土含量為10 wt%時，對水泥砂漿的抗壓強度和內部濕度增加、乾縮量減少、自收縮量減少和水泥漿的圓盤裂縫減低有最佳的提升效果。

    This thesis has prepared two zwitterionic hydrogels,Poly(acrylamide-co-sulfobetaine) (P(AM/SB)) and Poly(acrylamide-co-sulfobetaine)/montmorillonite (P(AM/SB)/MMT) by reactingacrylamide, N-(3-sulfopropyl)-N-methacroyloxyethyl-N,N-dimethyl-ammoniumbetaine(SB)and Montmorillonite through free radical polymerization.
    FT-IR was used to identify the functional groups of these hydrogels.
    The effects of monomer ratio, initiator and crosslinker dosage, andmontmorillonite content on the water absorbency of the resulted hydrogelsin various aqueous solutions were studied and discussed.
    P(AM/SB)/MMT hydrogel was added into cementitious materials. The effects of monomer ratio and Montmorillonite content on the weight loss, compressive strength, internal humidity, autogenous shrinkage 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 P(AM/SB)/MMT hydrogel with AM/SB = 8, APS = 0.5 mol%, MBA = 2.0 mole%, MMT = 10 wt% were 28.3 g/g in water and 54.0 g/g in Pore solution, repectively. P(AM/SB)/MMT hydrogel with 0.2 wt% dosage, particle size of 0.082 mm and 10 wt% Montmorillonite showed the best performance in cementitious materials. Namely, this polymer could decrease autogenous shrinkage and drying shrinkage, and increase the compressive strength and internal humidity in mortars, and reduce the craking formation in cement pastes.
