Advances in synthetic polymer chemistry have unleashed seemingly unlimited strategies for producing block polymers with arbitrary numbers (n) and types (k) of unique sequences of repeating units. Increasing (k,n) leads to a geometric expansion of possible molecular architectures, beyond conventional ABA-type triblock copolymers (k = 2, n = 3), offering alluring opportunities to generate exquisitely tailored materials with unparalleled control over nanoscale-domain geometry, packing symmetry, and chemical composition. Transforming this potential into targeted structures endowed with useful properties hinges on imaginative molecular designs guided by predictive theory and computer simulation. Here, we review recent developments in the field of block polymers.
合成聚合物化学的进步为生产具有任意数量 (n) 和类型 (k) 的独特重复单元序列的嵌段聚合物提供了看似无限的策略。增加 (k,n) 会导致可能的分子结构呈几何级数扩展，超出传统的 ABA 型三嵌段共聚物 (k = 2, n = 3)，为生成具有无与伦比的纳米域几何、堆积对称性和化学组成控制能力的精美定制材料提供了诱人的机会。将这种潜力转化为具有有用性质的目标结构取决于基于预测理论和计算机模拟的富有想象力的分子设计。在这里，我们回顾了嵌段聚合物领域的最新进展。
