Detailed Description

The atomic force microscope (AFM) is a powerful tool for investigating interactions across a surface.

It can create images of the surface morphology, measure the friction properties, or determine the conductivity across a sample rapidly with nanometre resolution. These modes can be used to investigate graphene/polymer composites to design improved materials. It can also analyse samples in a liquid environment and at a range of different temperatures, as well as perform electrochemical measurements.


Users can look at how supercapacitors or batteries made from 2D materials transform as they are charged and discharged, allowing for discovery of where the structure starts to fail. This will allow for the design of longer lasting and more efficient batteries.
