We study living polymerization initiated from concave surfaces. We clarify that, depending on different criteria for ceasing the reaction, different relationships between grafted chain polydispersity index and the grafting surface curvature can be categorized. The average molecular weight of the grafted chains monotonically decreases as the grafting surface curvature increases. These results shed light on better control and design of functional porous materials for use in bioimplanting or chemical sensors.
我们研究了从凹面引发的活性聚合反应。我们阐明，根据终止反应的不同标准，可以对接枝链多分散指数与接枝表面曲率之间的不同关系进行分类。接枝链的平均分子量随着接枝表面曲率的增加而单调降低。这些结果为生物植入或化学传感器中使用的功能性多孔材料的更好控制和设计提供了启示。
