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.
