Scientists at Drexel University have developed a way to create tiny nanoscrolls from MXene precursors. These ultra-thin structures are more conductive than their flat counterparts and could improve energy storage devices, biosensors, and wearable electronics.

Scientists at Drexel University have made a breakthrough in creating tiny nanoscrolls from MXene precursors. These ultra-thin structures are about 100 times thinner than a human hair and are even more conductive than their flat counterparts. This could significantly improve technologies such as energy storage devices, biosensors, and wearable electronics.

The researchers created the nanoscrolls by rolling flat MXene flakes into tiny tubular structures. These tube-like materials can strengthen polymers and metals or guide the movement of ions in batteries and desalination systems with far less resistance.

The team successfully applied their method to six types of MXenes, including two forms of titanium carbide, niobium carbide, vanadium carbide, tantalum carbide, and titanium carbonitride. They were able to consistently produce 10 grams of nanoscrolls with controlled chemical and physical properties.

The scroll-like structure not only improves electrical conductivity and mechanical strength but also changes how the material interacts with molecules. This makes it especially promising for sensing applications and advanced composite materials.
