The principal aim of the project is fabrication of nanostructures (dots, rods, wires, tubes) of materials with magnetic, electric and electrooptic activity via nanotemplating. The approach to formation of nanotemplates consists in combination of two phenomena: molecular assembly and microphase separation in block copolymers. Recently, we have shown that amphiphilic block copolymers are able to molecular assembly with low molar mass additives due to hydrogen bonding. The idea of nanostructure formation in thin films of block copolymer supramolecular assemblies has been proved in the frame of the current BMBF project "Optimization and characterization of nanotemplates from polymers". The supramolecular block copolymer approach was found to be simple, fast and effective way for nanomembrane formation. Two problems are to be solved for fabrication of nanostructures via templating. First, it is desired to extend the crystal-like ordering of the features from several square micrometers up to scale of millimeters. Second, the conditions of the deposition of the desired materials through templates are to be developed and optimized. Thus, we suggest to use electrodeposition of metals, especially those with magnetic properties (Ni, Co, Fe), and electrocondictive polymers to fabricate ordered arrays of nanodots, wires and tubes. Finally, in cooperation with another research groups, we are going to test the obtained nanomaterials with the focus on the properties arising from nanoscale and ordering of the fabricated structures.

该项目的主要目标是通过纳米模板制作具有磁、电和电光活性的材料的纳米结构（点、棒、线、管）。形成纳米模板的方法包括两种现象的组合：嵌段共聚物中的分子组装和微相分离。最近，我们发现两亲性嵌段共聚物能够与低摩尔质量的添加剂由于氢键而分子组装。嵌段共聚物超分子组装体薄膜中纳米结构形成的想法已经在当前BMBF项目"聚合物纳米模板的优化和表征"的框架中得到了证实。超分子嵌段共聚物法是一种简单、快速、有效的纳米成膜方法。通过模板法制备纳米结构需要解决两个问题。首先，期望将特征的晶体状排序从几平方微米扩展到毫米级。其次，需要开发和优化通过模板沉积所需材料的条件。因此，我们建议使用电沉积金属，特别是那些具有磁性的金属（Ni，Co，Fe）和导电聚合物来制备纳米点，线和管的有序阵列。最后，在与其他研究小组的合作中，我们将测试所获得的纳米材料，重点是纳米尺度和制造结构的有序性所产生的性能。
