  双链季铵表面活性剂体系中的囊泡到胶束的转变：界面行为和分子见解

  摘要：

  囊泡已成为一种有前景的药物载体，与细胞膜具有良好的相容性，在生物医学应用方面具有巨大的潜力。虽然大多数报道的胶束到囊泡的转变涉及增加表面活性剂或添加剂浓度，但反向囊泡到胶束的转变仍然很少被探索。在这项研究中，我们利用动态光散射、透射电子显微镜和荧光光谱研究了己基二甲基辛基溴化铵 (CCBr) 的囊泡到胶束的转变。为了进行比较，研究了具有相同链长的单链四烷基铵表面活性剂十四烷基三甲基溴化铵（TTABr）。通过化学捕获（CT）方法，我们探索了囊泡到胶束转变过程中界面组成的变化。值得注意的是，CCBr 表现出独特的特性，使其有别于 TTABr 和其他阳离子表面活性剂。在较低浓度范围内，水和溴离子的界面摩尔浓度同时增加，这表明界面头基摩尔浓度和表面活性剂分子堆积降低。此外，我们的耗散粒子动力学（DPD）模拟结果表明，随着表面活性剂浓度的升高，表面活性剂链之间的内角变宽，CCBr的分子构型接近直线。这些

  申请人：Toreki William

  公开号：US20090104144A1

  公开（公告）日：2009-04-23

  A novel gypsum board having improved antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antifungal agent effective at inhibiting fungal growth. A preferred polymeric antifungal agent is polyDADMAC or polyTMMC. The novel gypsum board further comprises a non-polymeric antifungal agent comprising a fluorine-containing quaternary ammonium compound. Preferred non-polymeric ammonium compounds include Tetra-n-butylammonium fluoride and Tetraethylammonium fluoride. The polymeric antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antifungal agent may be encapsulated in a material or ionically associated with the polymeric antifungal agent to allow releases of the non-polymeric antifungal agent over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.
