Investigation of the Stretchability of Specific Elastomeric Materials and their Application in Organic Electronics

新的技术和方法不断被开发，以超越目前硅基电子产品的性能极限。这导致了现代电子学新时代的兴起，其基础是可以通过其化学结构直接定制精确行为的材料。通过推动化学工程和合成化学的极限，获得了具有优异电子性能的溶液加工材料。然而，由这些材料制成的设备具有较低的机械应力耐受性，限制了它们在下一代可穿戴电子设备和传感器上的潜力，这将需要增强的机械灵活性。通过他们的研发活动，合作伙伴公司开发了新的聚乙烯基材料（PE），具有许多有趣的特性，包括低粘度和沸点，以及低玻璃化转变温度（Tg）。这对可伸缩电子产品特别有吸引力。为了推进包含这些新材料的电子设备的发展，需要对材料的机械性能进行精确和准确的表征。此外，评估材料与其他器件组件（电极、半导体等）之间的兼容性也很重要。该合作研究项目的目标是通过各种表征技术调查和测试合作公司最近开发的新型聚乙烯基材料的机械性能，并测试其与半导体聚合物和其他可拉伸电子元件的兼容性。这将通过几个表面和仪器表征来完成，包括原子力显微镜（AFM）和x射线衍射（XRD）。rondeau - gagn<s:1>小组开发的专业技术将允许对合作公司开发的新材料的机械性能进行全面调查。此外，研究目标的完成将为公司带来新的机会，特别是通过有前途的产品的价值增值。

New techniques and methodologies are constantly being developed to surpass the current performance limits ofsilicon-based electronics. This has led to the rise of a new era in modern electronics based on materials whoseprecise behaviour can be tailored directly through their chemical structure. By pushing the limits of bothchemical engineering and synthetic chemistry, solution-processed materials with excellent electronic propertieshave been obtained. However, devices built from these materials suffer from low mechanical stress tolerance,limiting their potential for next generation wearable electronics and sensors, which will require enhancedmechanical flexibilityThrough their R&D activities, the partner company developed new polyethylene-based materials (PE)possessing many interesting properties, including low-viscosity and boiling point, and low glass transitiontemperature (Tg), which are particularly attractive for stretchable electronics. In order to move forward with thedevelopment of electronic devices incorporating these new materials, a precise and accurate characterization ofthe mechanical properties of the materials is required. Moreover, the compatibility between the materials andother devices' components (electrodes, semiconductor, etc.) is important to assess.The objective of this collaborative research project is to investigate and test the mechanical properties of newpolyethylene-based materials, recently developed by the partner company, through various characterizationtechniques and test their compatibility with semiconducting polymers and other stretchable electroniccomponents. This will be accomplished through several surface and instrumental characterizations, includingatomic force microscopy (AFM) and X-ray diffraction (XRD). The expertise developed by the Rondeau-Gagnégroup will allow for a complete investigation of the mechanical properties of the new materials developed bythe partner company. Furthermore, the completion of the research objectives will bring new opportunities forthe company, especially through the valorization of a promising product.
