Patent

CA 2554636

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 stable complexes of rare earth nanoparticles by complexing rare earth ultrafine particles with oppositely charged-neutral di-block copolymers.

La présente invention concerne la maîtrise d'agrégation de particules de terre rare au moyen de copolymères bloc et des particules à base de terre rare. Plus particulièrement, cette invention concerne aussi la formation de complexes stables d'agrégats de terre rare par la complexion de particules à base de terre rare avec des copolymères di-bloc de charge opposée neutre. Plus particulièrement, cette invention concerne aussi la formation de complexes stables de nanoparticule de terre rare par une complexion de particules ultrafines de terre rare avec des copolymères di-bloc de charge opposée neutre..
