超浓乳液制备及稳定性研究

Study of Preparation and Stability of Super-Concentrated Emulsions

详细介绍了超浓乳液及相关术语、超浓乳液的制备及影响其稳定性的因素 ,并以苯乙烯为分散相、水为连续相对超浓乳液稳定性进行了详细的探究。从内因、外因两方面研究了影响超浓乳液稳定性的因素 ,结果表明 :分散相性质及体积分数、连续相性质、乳化剂和助乳化剂种类及用量、功能单体、电解质溶液浓度及合成工艺等对超浓乳液的稳定性有不同程度的影响。

Super concentrated emulsions and their related terminology, preparation of super concentrated emulsions and factors influencing their stability are described in details and study was made of stability of concentrated emulsions based on styrene used as dispersed phase and water as continuous phase. Factors influencing stability of concentrated emulsions were investigated from the point of internal and external causes. The results showed that nature and volume fraction of dispersed phase, nature of continuous phase, types and contents of emulsifiers and assisting emulsifiers, functional monomers, concentration of electrolyte solution and synthesis exerted influence to different extents on stability of super concentrated emulsions.
