In comparison with in-situ polymerization, more homogeneous hybrids with monodispersion of titania were synthesized by blending method.

同原位聚合法相比，共混法可更均匀的杂化体系，且TiO2为单分。

One of the main difficulty in synthesis core-shell magnetic polymers is the monodispersion of the magnetic nanoparticles in organic monomer.

核壳型高分子磁性材料主要的难点就是纳米四氧化三铁在有机单体中的均匀分。
