摘　　要：基于电导率的测定得到最大增容水量,探究表面活性剂种类、复配后亲水亲油平衡值(HLB)、用量、温度等因素对油包水(W/O)微乳液体系稳定性的影响。结果表明,以Span 80和Tween 80复配的表面活性剂,在HLB值等于5.5的条件下,W/O型微乳液的稳定性最佳。以此为基础,以甲基丙烯酸甲酯(MMA)和甲基丙烯酸丁酯(BMA)的共聚物为壁材,聚丙烯酰胺(PAM)水溶液为芯材,通过原位聚合法合成了微胶囊,并对其形貌及理化性质进行了表征。Based on the conductivity measurement to obtain the maximum capacity of water supply.The effects of surfactant type,HLB value,surfactant dosage and temperature on the stability of W/O microemulsion were investigated.The results show that the stability of W/O microemulsion is optimal under the condition that Span 80 and Tween 80 are surfactants and HLB is equal to 5.5.On this basis,the microcapsules were synthesized by in-situ polymerization with the copolymer of methyl methacrylate and butyl methacrylate as wall material and PAM aqueous solution as core material,and their morphology and physical and chemical properties were observed.It provides an effective way for the preparation of W/O emulsion microcapsules.
