University of Dublin researchers develop low-cost graphene production method

Researchers at the University of Dublin, led by Associate Professor of Materials Science Conor Boland, have developed a potentially low-cost method to produce graphene using electronic waste, old newspapers, tap water, and a blender.

Graphene is a material stronger than steel, extremely lightweight, and an excellent conductor of electricity. It is widely used in batteries, medical sensors, smartphones, and laptops. While approximately 62 million tons of graphene were produced globally in 2022, only 22.3% was correctly collected and recycled.

The primary challenge in recycling has been separating the single layers of carbon atoms without destroying them. The research team, working through the RAPID Institute, has utilized a patented process known as ‘liquid phase exfoliation’ to overcome this obstacle.
