    摘要:

    多糖是自然界中储量最大的天然高分子,其分子链通常具有结构上的两亲性,能够较好地吸附在相界面上并表现出改善固-液、液-液之间相容性的能力。 此外,多糖独特的理化结构使其在溶液中具有良好的流变学性质以及形成凝胶网络的能力,使多糖能够在较低表面活性下体现出较好的界面吸附能力,常被用于多相体系的乳化、分散、增稠和稳定。通过化学改性可对天然多糖进行亲水-疏水平衡,并赋予其一定的化学活性、表面电荷、流变性能等,能够获得性能更加优异的绿色大分子表面活性剂。基于此,该文主要介绍了多糖在表面活性剂中的应用,主要包括纤维素、淀粉、半纤维素、甲壳素、天然树胶等,并从多糖独特的理化性质、结构以及改性特点出发,剖析其对乳化、分散、破乳、增溶等表面活性作用的影响,阐述多糖及其衍生物在表面活性剂中的研究进展及应用潜力。 最后,对多糖表面活性功能增强改性的发展方向进行了展望。

    Abstract:

    Polysaccharide is the most abundant natural polymer in nature. The molecular chains of polysaccharides are usually substituted by hydrophobic side groups, giving them a natural amphiphilicity. Therefore, it can be well adsorbed onto the multiphase interface, having the ability to improve the compatibility between solid-liquid and liquid-liquid phases. In addition, the unique physicochemical structure enables polysaccharides to have good rheological properties in water and have the ability to form gel networks, which can exhibit good interfacial adsorption ability under low surface activity, so they are often used for emulsifying, dispersing, thickening and stabilizing multiphase systems. The balancing of the hydrophilic-hydrophobic level of polysaccharides was obtained by appropriate chemical modifications, which also give them special surface properties making an excellent green macromolecular surfactant. Based on this, the article mainly introduces the application of naturally abundant polysaccharides in surfactants, mainly including cellulose, starch, hemicellulose, chitin, natural gum, etc. The effects of chemical structures and modifications of polysaccharides on their emulsifying, dispersing, demulsifying, solubilizing properties were analyzed; the research progress and application potential of polysaccharides and their derivatives in surfactants were described.
