含油核聚2-氰基丙烯酸丁酯纳米微囊的制备研究

Study of Preparation of Polybutylcyanoacrylate Nanocapsules with Oil Core

通过改进的界面聚合方法合成了含油核聚2 氰基丙烯酸丁酯纳米微囊,重点研究了搅拌速率、pH值、乙醇浓度、溶剂等聚合条件对纳米微囊的粒径分布及规整性的影响.获得了平均粒径为150nm,壁厚为50nm结构规整的纳米微囊.

Polybutylcyanoacrylate (PBCA) nanocapsules with oil core were prepared by modified interfacial polymerization method.The influences of stirring rate, concentration of ethanol, pH value and solvent on nanocapsules diameter and regularity were investigated. The diameter of PBCA nanocapsules ranged from 100nm to 200nm, and the wall thickness of PBCA nanocapsules was about 50nm.
