    • Copolymers and methods using the copolymers control the stability, the homogeneity of mixtures and the chargeability of a nanoparticle. A block copolymer-nanoparticle composition includes first, second and third block units that each include repeating units of respective monomers. The monomer of the first block unit includes a binding group that binds to the nanoparticle. The monomer of the second block unit includes a hydrophobic moiety that provides steric stabilization of the nanoparticle and homogeneity of mixtures of the copolymer-nanoparticle composition in a non-polar medium. The monomer of the third block unit includes a chargeable group that imparts a charge to the nanoparticle. An order of the respective block units in the copolymer and the number of repeating units of the monomer in the respective block units control the stability, the homogeneity of mixtures and the charge of the nanoparticle.
    • 使用共聚物的共聚物和方法控制了稳定性,混合物的均匀性和纳米颗粒的带电性。 嵌段共聚物 - 纳米颗粒组合物包括第一,第二和第三嵌段单元,其各自包含各自单体的重复单元。 第一嵌段单元的单体包括结合纳米颗粒的结合基团。 第二嵌段单元的单体包括提供纳米颗粒的空间稳定性和共聚物 - 纳米颗粒组合物在非极性介质中的混合物的均匀性的疏水部分。 第三块单元的单体包括向纳米颗粒赋予电荷的可带电组。 共聚物中相应嵌段单元的顺序和各嵌段单元中单体的重复单元数控制了稳定性,混合物的均匀性和纳米颗粒的电荷。
