NANO2DAY is aimed to develop novel multifunctional composites with outstanding electronic and mechanical properties by incorporation of novel MXene nanosheets into polymer matrixes. NANO2DAY is a first step in the rational design and systematic exploration of MXene-polymer nanocomposites for wearable electronics and advanced structural components for airspace applications. The overall aim of the project is to provide new materials and technologies with better performance, efficiency, quality, and cost savings in their end-user applications. The concept explored in the project accounts for finding and extending the application potential of advanced MXene-doped polymers and validation of their effectiveness compared to well-known carbon-based and particularly graphene-doped polymers.
