The electrical characteristics of CNT mats and fibres strongly depend on the interactions between single CNTs. Tailoring of the CNT external wall surface properties prior to the formation of the mats/fibres has the potential to change the electrical properties.
The work within this project will seek to develop methods for altering the surface chemistry by means of adsorption and CVD growth from CNT surfaces. Two specific classes of coating materials will be targeted, inorganic metal oxide and organic polymers.
By modifying the surface chemistry we will be able to engineering the surface characteristics of the CNTs and therefore tailor the interaction at the walls interfaces when in mat/fibre form.
This work ties strongly with the energy storage, as well as our industrial partners who are seeking to conduct lighting strike or de-icing research.
