Dr Narelle Brack Head of Dept Chemistry & Physics, Physics

Dr Brack has 20 years postgraduate and professional experience in materials and surface science. She has published 3 refereed book chapters and over 70 refereed international journal articles and won significant research and infrastructure funding. She has extensive expertise in the development of surface modification processes and surface characterisation using X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (TOF-SIMS).

She has made significant and innovative contributions in research fields such as:
- Micro-patterning of fluoropolymer surfaces. This project focussed on the development of novel surface chemistries for micro-contact printing and innovative surface analytical techniques for their characterisation.

- Next generation aerospace materials. This project has developed a range of novel treatments for light weight metals and reinforcement materials for advanced aerospace materials. Significant insight into the fundamental adhesion mechanisms affecting the strength and durability of these materials has been achieved.

- Growth and manipulation of carbon nanotubes for advanced composite materials. This project investigated the controlled growth and surface modification of carbon nanotubes for improved strength advanced composite materials.

- Ultrasonicated ozone modification of exfoliated graphite and carbon nanotubes. This project investigated a novel ultrasonicated-ozonolysis (USO) processing method for exfoliated graphite with the aim of producing stable aqueous graphitic nanoplatelet dispersions that are suitable to ink jet printing applications. A second project investigated the mechanical and surface characterization of CNT-modified glass fibre interphases by creating model interphases on a planar-glass substrate, with the aim of accurately characterizing the chemical nature of the interphase region and understanding its role in performance.

In addition, Dr. Brack has contributed to a wide range of projects including, for example, protein interaction with resins, bacteria surface chemistry for waste water, mining and biodiagnostic applications, surface passivation of semiconductors, tailored polymer surface resistivity, the development of evacuated glazing technology, corrosion protection and passivation of metals, and the role of lubricants in metal forming.
