| 摘 要： | 采用高压法，以聚醚Ｆ－６８为全氟双下基乙烯的乳化剂、稳定剂，制备全氟碳化物乳剂和加盐乳剂．进行乳剂的不同温度老化实验，测定乳剂平均粒径，讨论该乳剂的稳定性、温度以及添加ＮａＣｌ对乳剂稳定性的影响，结果表明全氟双了基乙烯－聚醚Ｆ－６８乳剂稳定性较差，冷冻的乳剂以及较高温度都直接影响乳剂的稳定性，ＮａＣｌ对该乳剂稳定性未有明显作用．用Ｏｓｔｗａｌｄ熟化理论探讨影响全氟碳乳剂稳定性的因素．

| Abstract: | An emulsion and a salty emulsion of his(F-butyl)ethene were prepared with pluronic F- 68 as an surfactants, by using high-presure emulsification procedure.The average droplet size of emulsion in the diferent ageing time were measured. The influence of temperature and NaCl on the stability of emulsions were discussed. The emulsions showed lower stability. A frozen procedure and higher storage temperature would lower the stability. Salty emulsion exhibits the same stability as salty-free emulsion. The factor of influence on stability of the emulsions is discussed according to Ostwald Ripening Theory. |
