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

基于电活性棒-线圈嵌段共聚物和无机纳米粒子的纳米杂化材料的分级纳米结构控制

基本信息

项目摘要

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.
该提案的主题是通过分层方法基于电活性棒-线圈嵌段共聚物和无机纳米颗粒的纳米混合材料的结构控制。 - 在分子尺度上,将合成具有一个功能性电活性嵌段和一个非导电结构导向线圈嵌段的新型嵌段共聚物体系。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多孔模板,可以进一步填充无机材料。将制备与嵌段共聚物的牺牲嵌段相相容的表面官能化的尺寸和形状调谐的纳米颗粒。该结构导向嵌段还可以直接用作纳米反应器用于合成纳米颗粒。 - 在介观尺度上,将研究棒状-卷曲嵌段共聚物及其与纳米粒子的共混物在本体和薄膜中的相行为。该提案的一个主要目的是以这样的方式操纵所得的纳米形态,使得其对于印刷电子中的应用(例如,对于有机太阳能电池应用)变得有用。- 自下而上的自组装方法与自上而下的技术,如图形外延相结合,将进一步应用于分层控制的纳米结构,并诱导长程有序。在提案的最后阶段,将探索制造真实的设备的首次尝试。
