Networks of Carbon Nanotubes in Epoxy Matrices

This thesis deals with the formation, analysis and manipulation of carbon nanotube (CNT) networks suspended in epoxy matrices. Investigations are focused on the improvement of the electrical properties of the CNT/epoxy composites. The goal is to understand the influence of various parameters – such as CNT type, synthesis method, treatment, dimensionality and concentration, as well as polymer type and suspension processing method – on the electrical properties of the composites. The network formation of CNT in epoxy matrices is analysed using scanning electron microscopic (SEM), electrical, Raman spectroscopic and rheological techniques.
