二十多年来，制备形状规整、外壳毛茸茸的核壳型聚合物纳米对象一直是聚合物化学领域的研究热点。不同的方法，如那些涉及合成(接枝方法)和嵌段共聚物自组装(溶液和本体)的方法已经被用于制备这种纳米对象。在这些方法中，由于形状和结构的简单性和范围，涉及嵌段共聚物的本体自组装结构的方法引起了特别的兴趣。本文综述了利用双嵌段和三嵌段自组装结构在这一方向上取得的进展。结果表明，这种方法不仅可以制备简单形状的毛状纳米物体，如球状、棒状和片状，还可以制备形状和形态更复杂的纳米物体，如多室胶束，这是合成或溶液自组装方法无法获得的。此外，利用这种方法还可以制造出像Janus纳米对象这样有趣的结构。审查进一步强调了这种纳米物体在模板应用中的用途。
Fabrication of core-shell polymer nano-objects with well-defined shape and hairy shell has been a subject of immense interest in polymer chemistry for more than two decades now. Different approaches such as those involving synthesis (grafting approaches) and block copolymer self-assembly (solution as well as bulk) have been used for the preparation of such nano-objects. Of these approaches that involving bulk self-assembled structures of block copolymers have been of special interest because of the simplicity and range of shape and structures possible. The present review focuses on the advances which have been made in this direction using diblock and triblock self-assembled structures. It will be shown that this approach allows to fabricate hairy nano-objects of not only simple shapes such as spheres, rods, and sheets but also those with more complex shape and morphology such as multicompartment micelles, which are not possible to obtain with synthetic or solution self-assembly approaches. Furthermore, interesting structures such as Janus nano-objects could also be fabricated using this approach. The review further highlights the use of such nano-objects for templating applications.
