Postdoctoral Research Associate
Thurid studied Mechanical Engineering at the University Karlsruhe, Germany, and joined the Institute for Applied Computer Science at the Karlsruhe Institute of Technology for her PhD Thesis ("A new concept for the application of single-walled carbon nanotubes for the pH sensor technology").
After her dissertation, Thurid joined Prof. Alan Windle's group as PDRA in 2011, currently funded by the US Office of Naval Research.
Subject groups/Research projects
- Carbon Nanotubes:
I am mainly reponsible for the synthesis of CNT fibres and films and the optimisation of the synthesis process in order to achieve pure CNT fibres tailorable to required properties.
- Composite Materials:
The direct spinning process co-synthesises polymeric material which covers the CNT bundles, which we refer to casually as "goo". I am interested the effect of this synthesis by-product and am of the opinion that one way of tailoring the properties of as-spun CNT fibres is to add our own "goo", e.g. with a polymeric material of our own choice.
- Carbon Nanotubes Processing:
I investigate the optimisation of the direct spinning process of pure CNT fibres as well as post-synthesis techniques, both with the aim to tailor the CNT fibre properties to specific application.
- Physical Characterisation of Nanomaterials:
As one of my main duties is the spinning and optimisation of CNT fibres, the analysis of the produced materials is obviously imperative. The techniques I use as a matter of routine include TGA (material uniformity and catalyst residue characterisation), Raman (characterisation of CNT properties and defects), SEM-FIB / TEM (characterisation of structural properties of CNTs and fibre uniformity) and Favimat (mechanical properties).
Impurity control during synthesis of CNT fibres and enhancement of their mechanical performance
One of Thurid's main areas of research is to characterise and understand the role of impurities simultaneously synthesised during the Cambridge CNT fibre spinning process and to optimize the spinning process in order to avoid the co-creation of the impurities and so to produce pure CNT fibre with improved structure.
The other main aspect of Thurid's work is to improve the mechanical properties preferentially of the as-spun fibre such as tensile strength, stiffness and their consistency along the fibre by improved process control.
