摘要
用动态光散射方法研究了以聚丙烯酸丁脂(PBA)为核、聚甲基丙烯酸甲脂(PMMA)为壳的核壳双层纳米颗粒的粒径和粒径分布。得出的结论为:由于同一粒径的单层介质颗粒和核壳双层纳米颗粒的散射光不同,在测量中若将核壳双层颗粒当作单层介质颗粒处理时,必将影响测量结果的表征。
The size and size distribution of core-shell particles, light scattering. Due to the difference of the light scattering by single pression of measured result must be influenced, if core-shell particles PBA as core and PMMA as shell, are studied by dynamic particles and core-shell particles in the same size, the exare regarded as single particles.
