Briefing
|
- New Graphene Producing Technique – National University of Singapore researchers developed new way to produce graphene on large scale at lower costs
- Graphene’s Potential – Graphene heralded as wonder material for unique electronic properties that can be used in touch screens, conductive inks, and fast-charging batteries
- Scaling Problem – Currently difficult to produce high-quality graphene affordably on large scale, limiting widespread adoption by industries
- How New Technique Works – Pre-treated graphite is exfoliated under high alkaline condition to trigger process called flocculation, where layers cluster to form graphene slurry, which can then be separated into monolayers when needed or stored away for months
- Environmentally Sustainable – Procedure requires 50 times less solvent than traditional graphene production processes, making it more environmentally sustainable
- Conductive Graphene Aerogels – Resulting graphene slurry can also be used to 3D print conductive graphene aerogels, light sponge-like material used to clean oil spill in sea
