Membrane from Deakin University is made of aramid nanofibers with boron nitride that harvest osmotic energy while providing structural reinforcement.


  • Robust
  • Scalable


  • Renewable energy

UN Sustainable Development Goals Addressed

  • Goal 7: Affordable & Clean Energy

  • Goal 13: Climate Action

The Challenge

Standard osmotic energy generators are consistently made of clay, graphene oxide, MXene, and molybdenum disulfide nanomaterials. Over time, these materials disintegrate, and the membrane becomes unusable.

Innovation Details

The nanocomposite membrane is an osmotic energy generator that leverages the pressure and salinity gradient between salt and fresh water to create energy. The membrane is made of aramid nanofibers and boron nitride. The boron nitride is the nanosheet base that facilitates the ion transport and the aramid nanofibers provide the structural reinforcement.
