Objectives Harnessing electricity from mechanical energy (by piezoeletricity) has been recognized as one of the the most emerging and promising technologies recently, not only to sustain self-powered systems in a feasible and economically practical alternative, but also to reduce the greenhouse gas emissions and sustain the environment. This project thus focuses on the development of novel high-performance piezoelectric-based energy harvesting coatings using MXene (2D layered transition metal carbides, carbonitrides and nitrides) for self-powering of nonwovens, to fulfil the power requirement of new and forthcomming applications arrising from e-mobility as well as next-generation of functional clothing and footwear.
Specific phases and stage of realization The following specific scientific and technological objectives are defined:

  • Define the stability and processability of MXenes-based inks.
  • Define the effect of nanocellulose surface charge and MXene chemical structure, morphology and solid content ratio on the microstructures of solvent-casted films and modulation of el. resistance / conductivity, electromechanical / piezoelectric and electrochemical storage ability.
  • Define the effect of MXene on crystallinity, flexibility, and strength on functional properties of the films prepared from conductive or piezoelectric polymer.
  • Develop a technological relevant procedure for 3D functionalization of nonwovens with selected MXene based inks using different coating technologies.
  • Validate generated power from vibrations / movements (simulation) of representative nonwoven with energy harvesting properties
