| 摘 要： | 运用动态光散射仪研究PBA(聚丙烯酸丁脂)为核,PMMA(聚甲基丙烯酸甲脂)为壳的核壳双层结构颗粒的角度散射光,并通过测量得到的粒径分布进行理论计算,结果表明:测量结果与理论计算结果总体趋势一致,但在前向散射和后向散射两者相差较大,主要由于动态光散射仪测量粒径分布时反演算法剔除占比例很小的大颗粒造成的.

| Abstract: | The characteristic of light scattering by PBA/PMMA core-shell nano-particles, PBA as core and PMMA as shell, were obtained by dynamic light scattering. It is shown that the general tendency of characteristic of light scattering with angles is consistent, but obviously different in forward and backward, because the large particles, accounting for a very few, was eliminated when inverting diameters in measurement. |
