Hierarchical nanostructure control of nanohybrid materials based on electroactive rod-coil block copolymers and inorganic nanoparticles

本课题的主题是基于电活性棒圈嵌段共聚物和无机纳米颗粒的纳米杂化材料的结构控制。在分子尺度上，新型嵌段共聚物体系将被合成，该体系具有一个功能性电活性嵌段和一个非导电定向结构线圈嵌段。线圈块将允许进一步修改与聚合物类似的反应：选择性降解将导致纳米孔模板，可以进一步填充无机材料。将制备与嵌段共聚物牺牲嵌段相相容的表面功能化尺寸和形状调谐纳米颗粒。结构导向块也可以直接作为纳米反应器用于纳米颗粒的合成。在介观尺度上，棒状线圈嵌段共聚物及其与纳米颗粒共混物的相行为将在整体和薄膜中进行研究。该提案的一个主要目的是操纵产生的纳米形态，使其能够用于印刷电子产品的应用，例如有机太阳能电池的应用。-自下而上的自组装方法与自上而下的技术（如石墨外延）相结合，将进一步应用于分层控制纳米结构和诱导长程有序。在提案的最后阶段，将探索制造真实设备的第一次尝试。

The subject of this proposal is the structure control of nanohybrid materials based on electroactive rod-coil block copolymers and inorganic nanoparticles via a hierarchical approach. - On the molecular scale, novel block copolymer systems will be synthesized which bear one functional electroactive block and one non-conducting structure-directing coil block. The coil block will allow further modification with polymer analogous reactions: Selective degradation will lead to nanoporous templates which can be further filled with inorganic materials. Surface-functionalized size- and shape-tuned nanoparticles will be prepared which are compatible with the sacrificial block phase of the block copolymers. The structure-directing block can also be directly used as nanoreactor for the synthesis of nanoparticles. - On the mesoscopic scale the phase behaviour of the rod-coil block copolymers and their blends with nanoparticles will be studied both in bulk and in thin films. One main aim of the proposal is to manipulate the resulting nanomorphology in such a way that it becomes useful for applications in printed electronics, e.g. for organic solar cell applications. - The combination of the bottom-up self-assembly approach with top-down techniques, such as graphoepitaxy, will be further applied to hierarchically control the nanostructures and to induce long-range order. At the last stage of the proposal first attempts to the fabrication of real devices will be explored.
