使用二嵌段共聚物的稀土聚集体配制物
摘要：
本发明涉及用嵌段共聚物和稀土基微粒来控制稀土微粒的聚集。更具体地说，本发明还涉及通过使稀土基微粒与二嵌段共聚物复合来制备稳定的稀土聚集体复合物，该二嵌段共聚物是(带有与稀土基微粒所带电荷相反电荷的链段)-(中性链段)二嵌段共聚物。更具体地说，本发明还涉及通过使稀土超细微粒与二嵌段共聚物复合来制备稳定的稀土纳米微粒复合物，该二嵌段共聚物是(带有与稀土超细微粒所带电荷相反电荷的链段)-(中性链段)二嵌段共聚物。
摘要（英）：

The present invention is directed to controlling aggregation of rare earth particles using block copolymers and rare earth base particles. More particularly, invention is also directed to forming stable complexes of rare earth aggregates by complexing rare earth base particles with oppositely charged-neutral di-block copolymers. Even more particularly, invention is also directed to forming stablecomplexes of rare earth nanoparticles by complexing rare earth ultrafine particles with oppositely charged-neutral di-block copolymers.
