摘要:

多糖类大分子具有天然、无毒、使用安全和可再生及来源丰富等优点. 将多糖类大分子与表面活性剂复配使用, 不仅可利用各自的优势和特性, 而且能发挥二者的协同作用, 大大改善二者的性能. 由于两者之间存在诸如静电作用、疏水作用、偶极相互作用、氢键作用、空间位阻效应等, 水体系中表面活性剂在多糖分子链上的缔合得到调控, 并引起表面活性剂的临界聚集浓度(cac)、临界胶束浓度(cmc)、结合量, 以及体系的表面吸附、界面流变性等呈现各种变化. 本文简要总结了近年来多糖类大分子与表面活性剂复配体系研究方面取得的一些进展, 述及复配体系研究中所采用的方法与手段, 主要讨论复配体系的物理化学性质以及多糖类大分子与表面活性剂相互作用的机制.

Abstract:

Polysaccharides are naturally occurring, nontoxic, safe, and abundant. However, the properties and functions of polysaccharides can be improved by mixing them with surfactants because of synergistic effects between them. The association of surfactants with polysaccharide chains can be regulated in aqueous systems through electrostatic, hydrophobic, dipolar, and hydrogen bonding interactions and steric hindrance effects, resulting in changes in the critical aggregation concentration (cac), critical micelle concentration (cmc), binding amount, surface adsorption, and interfacial rheology of aqueous systems. In this paper, recent progress of research on mixed systems of polysaccharides and surfactants, including measurement methods, are summarized. The physicochemical properties and interaction mechanisms of these mixed systems are explored.

Key words: Polysaccharide, Surfactant, Mixed system, Synergistic effect, Physicochemical property
