Janus nanodiscs of diblock copolymers are prepared by stepwise disassembly of PS-b-P4VP disc-stacked particles. The Janus nanodiscs are uniform in thickness and regular in contour. By preferential growth of functional materials at the positively charged P4VP side, the composition, microstructure, and performance of the Janus nanodiscs are tunable.
两亲嵌段共聚物的 Janus 纳米盘通过 PS-b-P4VP 盘堆叠颗粒的分步解组装制备而成。Janus 纳米盘厚度均匀,轮廓规则。通过在带正电荷的 P4VP 侧优先生长功能材料,可以调节 Janus 纳米盘的组成、微结构和性能。
