【摘要】 综述了在不同胶体体系(乳液、双重乳液、微乳等)中合成纳米胶囊的研究工作,介绍了纳米胶囊新型的合成手段,包括界面聚合法、界面沉积法、复相乳液溶剂挥发法、聚电解质的逐步沉积法和微乳聚合法等不同的制备方法。并从纳米胶囊的粒径、包裹率、Zeta电位、热敏性和酸碱敏感性等方面分析了纳米胶囊的物理化学性能。更多还原

【Abstract】 Nanocapsules are a kind of tiny colloid particles with nano-size. The paper described the formation of nanocapsules in different colloid systems (emulsion,double emulsion,microemulsion etc.). The new preparation methods for nanocapsules were introduced,including interfacial polymerization, interfacial deposition,solvent volatilization in complex phase emulsion,stepwise deposition of polyelectrolytes and microemulsion polymerization. The physicochemical characteristics of nanocapsules,such as particle size,rate of capsulation,Zeta potential,heat-sensitivity and pH-sensitivity were also reviewed.更多还原
