微封装法制备聚苯乙烯空心微球的改进

IMPROVEMENT ON PREPARATION OF PS MICROSHELLS BYMICROENCAPSULATION

主要介绍了密度匹配微封装技术，利用此项技术制备的聚苯乙烯空心微球球形度好于９９％，同心度好于９８％。另外还对球壳内壁气泡问题及大直径球壳的制备进行了讨论。

Densitymatched microencapsulation technique was presented in this paper. Concentricity, sphericity of microshells prepared by the technique was typically more than 98%, 99% respectively. Reduction of vacuole in the wall and preparation of large diameter microshells were also discussed.
