Amphiphilic polymer conetworks are cross-linked polymers that swell both in water and in organic solvents and can phase separate on the nanoscale in the bulk or in selective solvents. To date, however, this phase separation has only been reported with short-range order, characterized by disordered morphologies. We now report the first example of amphiphilic polymer conetworks, based on end-linked "core-first" star block copolymers, that form a lamellar phase with long-range order. These mesoscopically ordered systems can be produced in a simple fashion and exhibit significantly improved mechanical properties.
两亲性聚合物互穿网络是一种交联聚合物，它在水和有机溶剂中都会溶胀，并且在本体或选择性溶剂中能够在纳米尺度上发生相分离。然而，迄今为止，这种相分离仅报道为具有短程有序，其特征是形态无序。我们现在报道了首例基于端基连接的“核-先”星形嵌段共聚物的两亲性聚合物互穿网络，它形成了具有长程有序的层状相。这些介观有序体系能够以简单的方式制备，并且展现出显著改善的机械性能。
