Based on the interaction of polyaluminum chloride (PAC) and chitosan (CTS) at the molecular level, an organic/inorganic composite material was designed for the preparation of alkyl ketene dimer (AKD) emulsion. This paper aimed to explore the influence of PAC/CTS on the physicochemical properties, microstructure, and sizing efficiency of AKD emulsions. The PAC/CTS complex forms a denser adsorption layer at the oil-water interface at the microscopic level. With the increase in CTS concentration, the AKD emulsions displayed excellent stability after high-speed centrifugation. In addition, the addition of CTS can effectively improve the sizing efficiency of the emulsion. Therefore, this study proposed a strategy of PAC/CTS as an emulsifier, and the related interaction mechanism was explored, which further expands the application of inorganic/organic composites in the field of colloidal chemistry.
基于聚合氯化铝(PAC)与壳聚糖(CTS)在分子水平上的相互作用,设计了一种用于制备烷基烯酮二聚体(AKD)乳液的有机/无机复合材料。本文旨在探究PAC/CTS对AKD乳液的物理化学性质、微观结构及施胶效率的影响。PAC/CTS复合物在微观层面的油水界面形成了更致密的吸附层。随着CTS浓度的增加,AKD乳液在高速离心后表现出优异的稳定性。此外,CTS的添加可有效提高乳液的施胶效率。因此,本研究提出了以PAC/CTS作为乳化剂的策略,并探究了相关的相互作用机制,进一步拓展了无机/有机复合材料在胶体化学领域的应用。
