| Zusammenfassung: | 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 |
