(277g) Realisation of the Potential of Practical Graphene Oxide Membranes for Molecular Separations

Membrane-based separation technologies have many advantages over traditional separation methods such as adsorption, and distillation in terms of energy- and cost-efficiency and modular deployment of technology. In practice, these advantages can be meaningfully harnessed only if advanced membranes with properties such as high permeance, tailorable selectivity [1-2], chlorine, pH and solvent resistance [3-4], low-fouling characteristics [1], long-term stability under operational conditions [5,6] alongside green and sustainable manufacturability [6] are demonstrated. In the last 5-6 years, our research group has taken rapid strides to realise these properties in membranes made from graphene-oxide. In this talk, I will summarize this journey reflecting on our work including some aspects of translation to industry and future directions.
