项目摘要

Material degradation is a primary concern to every material scientist and engineer, not only does degradation lead to failure, but results in the need for repair - a very costly endeavour. In this perspective, it is of interest to develop self-healing materials that will make maintenance redundant. As opposed to inorganic semiconductors, organic semiconducting materials are soft, which makes them ideal to be used in flexible and stretchable electronic devices, which can be directly applied to the human skin. Wearable electronics, however, are particularly prone to mechanical damage and fatigue, which is why it is paramount to develop more robust materials, like self-healable semiconductors.This fellowship will, for the first time, make it possible to synthesise intrinsic self-healing organic semiconductors and incorporate them into fully flexible, stretchable and wearable electronic devices, respectively bionic skin, to measure biological metabolites associated with diabetes (glucose), fatigue (lactate) and stress (cortisol). The electric charges will be transported via the conjugated polymer backbone, while additional supramolecular functionalities (i.e. non-binding interactions) will be incorporated into the chemical structure to ensure self-healing via the formation of dynamic bonds. The study of the new self-healing polymers will then be extended to other dynamically bonding functional groups to evaluate which chemistry is best suited for organic semiconductors. Subsequent steps will focus on the self-healing dynamics and rates, and the incorporation of the new materials into flexible electronic prototype devices.The realisation of healable organic semiconductors, for the first time, will allow the fabrication of lightweight, -wearable sensors directly applied to the human skin. This will make it possible to continuously monitor medically relevant body functions and present a significant step forward in the development of affordable biological sensors and continuous patient monitoring, ultimately enhancing medical diagnostics and opening-up new treatment possibilities.

材料降解是每个材料科学家和工程师最关心的问题，降解不仅会导致故障，还会导致需要维修——这是一项成本高昂的工作。从这个角度来看，开发能够使维护变得多余的自我修复材料是很有意义的。与无机半导体相反，有机半导体材料柔软，这使得它们非常适合用于柔性和可拉伸的电子设备，可以直接应用于人体皮肤。然而，可穿戴电子产品特别容易受到机械损坏和疲劳，这就是为什么开发更坚固的材料（例如自愈半导体）至关重要的原因。该奖学金将首次使合成内在自愈功能成为可能有机半导体并将其整合到完全柔性、可拉伸和可穿戴的电子设备中，分别是仿生皮肤，以测量与糖尿病（葡萄糖）、疲劳（乳酸）和压力（皮质醇）相关的生物代谢物。电荷将通过共轭聚合物主链传输，而额外的超分子功能（即非结合相互作用）将被纳入化学结构中，以确保通过动态键的形成进行自我修复。然后，新型自修复聚合物的研究将扩展到其他动态键合官能团，以评估哪种化学最适合有机半导体。后续步骤将重点关注自修复动力学和速率，以及将新材料纳入柔性电子原型设备。可修复有机半导体的实现将首次允许制造直接应用的轻质可穿戴传感器到人体皮肤。这将使持续监测医学相关的身体功能成为可能，并在开发负担得起的生物传感器和持续患者监测方面迈出重要一步，最终增强医疗诊断并开辟新的治疗可能性。
