中文摘要： 纳米粒子在小于50 nm的尺度下自组装形成有序规则阵列结构是一个具有挑战性的研究课题。本项目以等离子体刻蚀的嵌段共聚物模板作为载体，利用简单的物理或化学原理，发展一种简单，普适的大面积构筑小于50nm尺度，模板化组装水溶性纳米粒子有序阵列结构的新方法。研究内容主要包括：（1）不同种类各向异性金属纳米粒子在模板上的可控组装；（2）在成功构筑单一组分纳米粒子阵列的基础上，构建多组分、多层次的功能性纳米粒子阵列结构；（3）不同种类生物纳米粒子在模板上的有序组装；（4）探索不同纳米粒子阵列体系的光学、催化、生物方面的特性。通过解决纳米阵列构筑方面的基础问题，希望为功能材料按照理想方式组装成高度有序结构提供一条有效的途径。

英文摘要： The self-assemble sub-50nm nanoparticles into highly ordered nanoarrays remain a challenging issue. By taking advantage of simple physical or chemical interactions, a facile and general method to fabricate the large area sub-50nm nanoparticle arrays on the plasma-etched block copolymer templates was demonstrated, which is new and effective for the assembly of water-dispersed nanoparticles. Here our studies include: (1) Controllable self-assembly of different types of anisotropic nanoparticles into highly ordered nanostructures; (2) Fabrication of multicomponent, multilevel hybrid nanostructures after successful formation of the first-level nanoparticle arrays; (3) Controllable self-assembly of different biomolecules into highly ordered structures; (4) Applications such as optical, catalysis and biological functions will be examined based on different nanoparticle arrays. Through understanding the fundamental process in nanostructure fabrication, this assembly strategy is expected to be a versatile approach, which may open a new route for the controlled assembly of functional nanostructured materials into large-scale ordered arrays with desirable patterns.
