Block copolymer supramolecular assemblies functionalized with magnetic nanowires

该项目的目的是通过嵌段共聚物系统的自组织获得有序纳米结构（点，线，管）的功能化，该系统将通过电沉积填充磁性和电活性材料。研究的出发点是两亲性嵌段共聚物与低摩尔质量添加剂通过微相分离进行自组装，其中结构由选择性氢键控制。在运行的项目中，它已被证明，这种超分子嵌段共聚物的方法是一种通用的，快速和有效的纳米膜形成的方法。未来的工作将集中在改进的长程有序，进一步减少的直径和获得的纳米物体的纵横比的变化。在第二步中，这些模板将通过电沉积用磁性金属和合金（Ni、Fe、CoPt、FePt）以及磁性聚合物（聚噻吩、聚苯胺）填充。该部分包括对纳米模板约束的沉积过程的分析和对磁性材料均匀填充的沉积过程的优化。磁和电特性将被详细分析，以了解在这个定义良好的纳米几何形状的各向异性和相互作用的复杂作用。这些磁记录模板的应用潜力将进行评估。一个在纳米线的磁性和电学方面具有经验的新团队的加入增强了现有团队的能力，并在该领域开辟了新的路线。

Aim of this project is the functionalisation of ordered nanostructures (dots, wires, tubes) obtained via self-organization of block copolymer systems, which will be filled with magnetic and electric active materials by electro-deposition. Starting point is the self-assembly of amphi-philic diblock copolymers with low molar mass additives by microphase separation, where struc-ture is controlled by selective hydrogen bonding. In the running project it has been shown that this supramolecular block copolymer approach is a versatile, fast and effective way for nanomembrane formation. Future work will focus on the improvement of long range ordering, further reduction of the diameter and variation of the aspect ratio of obtained nano-objects. In a second step, these templates will be filled by electrodeposition with magnetic metals and alloys (Ni, Fe, CoPt, FePt), and electroconductive polymers (polythiophene, polyaniline). This part includes the analysis of the deposition process constrained by the nanotemplate and the optimisa-tion of the deposition process for homogeneous filling with the magnetic material. Magnetic and electrical properties will be analyzed in detail in order to understand the complex role of anisotropies and interactions in this well defined nanoscale geometry. The application potential of these templates for magnetic recording will be evaluated. The incorporation of a new group with experience on magnetic and elctrical aspects of nanowires enhances the capabilities of the existing team and opens new routes in this area.
