摘要

自組裝(self-assembly) 為系統之構成元素在無外力介入下，自行聚集、組織成規則性結構的現象，其為建構奈米材料非常重要的方法，這種由下而上（bottom-up）方法目前被廣泛應用來製備具光、電、磁、感測、與催化功能的奈米材料。高分子鏈具有奈米級的尺寸，故相當適合用來作為奈米材料的建構單元(building block)；如團聯式共聚合物、高分子錯合體等可呈現豐富的自組裝奈米結構，可作為奈米模版，用來製備奈米複合材料、奈米孔狀材料、光子晶體等。本文特別以團聯式共聚合物為例來說明高分子豐富的自組裝行為。

Self-assembly is the autonomous organization of components into ordered structures without human intervention. Self-assembly has founded the basis for the ＂bottom-up strategy＂ of constructing functional and smart nano-materials potentially useful for optical and electronic devices, sensors, catalysts, etc. Among the variety of self-assembled materials, polymer offers an attractive building block for constructing nanostructured materials due to the nanoscale characteristic dimension of polymer molecules. For instance, block copolymers can self-assemble into a series of long-range ordered nanostructures which can be considered as templates for fabricating nanocomposites, nanoporous materials and photonic crystals. In this article, diblock copolymer is taken as the example to demonstrate the rich and complex self-assembly behavior of polymers.
