| 摘 要： | 通过溶剂蒸发法制备了十六烷/聚甲基丙烯酸甲酯核/壳结构微胶囊。SEM和光学显微镜照片显示,微胶囊呈球形,囊壁透明,表面光滑。系统研究表明,在相同条件下,随着PMMA用量的增加,微胶囊粒径增大,粒径分布变宽;随着搅拌速度的增加或/和稳定剂PVA量的增大,微胶囊的粒径减小,粒径分布变窄。

| Abstract: | Microcapsules containing hexadecane as core material were prepared from polymethyl methacrylate(PMMA) by the solvent evaporation method.Systematic researches for the influence of PMMA/hexadecane mass ratio,surfactant PVA concentration as well as stirring rate on the capsule diameter and capsule size distribution were carried out.It is found that the diameter and the particle size distribution of the capsules increase with increasing PMMA/hexadecane mass ratio,while decrease with increasing the stirring rate... |
