A goal of this project was to develop a fabrication process of nano-structured materials with a size ranging to deca-nano meter level (〜10^0 nm), where can not be reached with advanced lithographic techniques. Block copolymer nanostructures are built up with controlled polymerization of well-designed functional monomers and self-assembling of the resulting block copolymers, leading to deca-nano assemblies with two step bottom-up process, i.e., design of functional monomers and self-assembling of block copolymers. In order to elevate this project to the goal, the block copolymers were employed to be utilized as nanotemplates, which can make various kinds of materials nanostructured with specific shapes and sizes exactly same as those of block copolymers. One of advantages of block copolymer systems is to significantly expand processing areas, which can be applied for large area fabrications. During the term of this project, unique block copolymers consisting of hydrophilic polyethylene oxide block (PEO) and hydrophobic polymethacrylate with liquid crsytallin side chains were successively produced and the highly ordered hexagonal cylindrical phase structures were reproductively fabricated in the films. The various kinds of materials such as metals, metal oxides, ceramics, semiconductors, and polymers were utilized to incorporate into the PEO domains. The resulting hybrid thin film exhibited the hexagonal cylinder array structures which had exactly same nano-futures with the block copolymers on the substrates. Furthermore, nanostructure-specific functions in electric, electronic, magnetic, and optical properties were successfully extracted. The hybrid thin film especially showed anisotropic electrochemical conductivity through the functionalized PEO cylinders, which could be essential on new device fabrications such as biofilter, organic solar cell, artificial ion-channel, and anisotropically conducting nanowire.

该项目的一个目标是开发一种纳米结构材料的制造工艺，其尺寸范围为十纳米级（10^0 nm），这是先进的光刻技术无法达到的。嵌段共聚物纳米结构是通过精心设计的功能单体的受控聚合和所得嵌段共聚物的自组装来构建的，从而通过两步自下而上的过程（即，功能单体的设计和嵌段共聚物的自组装。为了将这一课题推向更高的水平，人们将嵌段共聚物作为纳米模板，利用其可以制备出与嵌段共聚物完全相同的纳米结构材料。嵌段共聚物体系的优点之一是显著地扩大了加工区域，其可以应用于大面积制造。在本项目期间，成功制备了由亲水性聚环氧乙烷嵌段（PEO）和疏水性聚甲基丙烯酸酯组成的具有液态侧链的嵌段共聚物，并在薄膜中再现性地制备了高度有序的六方柱相结构。各种材料，如金属，金属氧化物，陶瓷，半导体和聚合物被用来纳入PEO域。所得的杂化薄膜表现出六方柱阵列结构，其与基底上的嵌段共聚物具有完全相同的纳米未来。此外，纳米结构的特定功能，在电，电，磁，光特性被成功地提取。该杂化薄膜通过功能化的PEO圆柱体特别显示出各向异性的电化学导电性，这对于诸如生物过滤器、有机太阳能电池、人工离子通道和各向异性导电纳米线等新器件的制备是必不可少的。
