摘要
乳液是一种良好的分散体系,可用于医药、食品、材料等领域.纳米粒子可以有效提高乳液的稳定性,因此,纳米粒子稳定乳液及液滴聚并动力学研究对于稳定乳液的制备及应用具有重要意义.纳米粒子润湿性、尺寸、形状、浓度、携带电荷类型等均会对颗粒与液滴间的相互作用产生影响,进而影响液滴间的聚并行为.对纳米粒子与液滴间的作用机制进行了介绍,并对液滴的聚并动力学研究进展进行了综述,同时对未来的研究方向进行了展望.
Abstract
Emulsion is a good dispersion system,which could be used in medicine,food,materials and other fields.Nanoparticles could effectively improve the stability of the emulsion,accordingly,the studies on nanoparticles stabilizing emulsions and droplet coalescence dynamics are of critical importance for the preparation and application of stable emulsions.The wettability,size,shape,concentration of nanoparticles and charge type carried by nanoparticles all affect the interaction between nanoparticles and droplets,and then affect the coalescence behavior between droplets.This article introduces the interaction mechanism between nanoparticles and droplets,reviews the research progress of droplet aggregation dynamics,and looks forward to future research directions.
