中文摘要 本研究首先利用自發–強制性製程,在正丙醇溶液中,以陰陽離子界劑(DTMA-DS)添加額外的離子型界劑(SDS/DTMAB),製備出穩定的帶電陰陽離子液胞,並探討組成、離子型界劑的碳鏈長度及界劑總濃度對帶電陰陽離子液胞物理穩定性的影響。然後嘗試在穩定的帶電液胞溶液中加入水溶性高分子,令其增稠及膠化,探討兩者之間的交互作用及相關疏水絮集現象。在膠化的研究中,帶電陰陽離子液胞的總濃度為5~30 mM,使用的水溶性高分子共四種,包括羥基乙基纖維素(HEC,250MR,P0)、經疏水改質之羥基乙基纖維素(HMHEC,Plus330,HMP0)、三甲基銨衍生物(cat-HEC,JR400,P+)及二甲基十基銨衍生物(cat-HMHEC,LM200,HMP+),添加量為0~9 wt%。液胞與高分子的混合溶液除了使用雷射光散射法粒徑/界面電位測定儀量測粒子特性外,也使用流變儀量測其交聯特徵。
實驗結果建立了四個液胞/高分子系統的相圖,並確立各種液胞/高分子混合溶液的流變特性及交聯特徵。此外,經由上述具有正、負及不同大小界面電位的液胞分別與帶電/不帶電、疏水性修飾/無疏水性修飾等四種高分子的交互作用結果,也增進對靜電及疏水效應在分子間交互作用及絮集現象中扮演的角色的了解。
英文摘要 In a preliminary work, the stable charged catansomes was prepared by mixing ionic surfactants (SDS/DTMAB) with catanionic surfactant (DTMA-DS) in 1-propanol solution through semi-spontaneous process and the influence including compositions, tail-length of ionic surfactants, and total surfactant concentration (5~30 mM) on the physical stability of charged catansomes was investigated by measuring the diameter and zeta potential as a function of time. Furthermore, the gelation of charged catansomes (XDS = 0.3~0.6, total surfactant concentration = 10 mM) by four polymers- HEC, HMHEC, cat-HEC, and cat-HMHEC (0~9 wt%) was systematically studied by using tube inversion and rheology.
Four phase maps were successfully documented for surfactant-polymer mixtures and property of rheology and characteristic of cross-linking for every system were established. Additionally, the experimental results (as represented by the relaxation time and the storage modulus at 1 Hz) of the interactions between charged catansomes with different zeta potential and polymers with and without charge, with and without hydrophobic modification revealed that what a role they play in vesicle-polymer mixtures.
