The invention provides a class of block copolymers having a plurality of chemically different blocks, at least a portion of which incorporating polymer side chain groups having a helical secondary structure. The invention also provides structures generated by self-assembly of polymer blends including at least one block copolymer component, such as a brush block polymer or wedge-type block polymer. The invention provides, for example, periodic nanostructures and microstructures generated by self-assembly of block copolymers and polymer blends comprising a mixture of at least one block copolymer component, such as a brush block copolymer, and at least a second component.
本发明提供了一类具有多个
化学性质不同嵌段的嵌段共聚物,其中至少有一部分嵌段共聚物含有具有螺旋状二级结构的聚合物侧链基团。本发明还提供了包括至少一种嵌段聚合物成分的聚合物混合物自组装产生的结构,例如刷状嵌段聚合物或楔形嵌段聚合物。例如,本发明提供了通过嵌段共聚物和聚合物混合物的自组装产生的周期性纳米结构和微结构,聚合物混合物包括至少一种嵌段共聚物组分(如刷型嵌段聚合物)和至少第二种组分的混合物。
