A fully funded Phd studentship in the Department of Physics & Astronomy, University of Sussex
Ceramic materials within X-ray scanners can lose mechanical integrity due to deleterious charging. Imparting an electrical dissipative coating to the ceramic or creating a ceramic composite containing conductive particles may offer a cost-effective solution. It is well known that when conducting particles are distributed in an insulating matrix, there is a statistical threshold at which current can flow through the composite when the filler particles are macroscopically inter-connected. In collaboration with Advanced Material Development, the Sussex Team have previously produced conducting graphene materials from graphene oxide by thermal reduction within a polymer matrix. GO thermal reduction is highly exothermic and can result in spontaneous ignition, while thermal runaway gives estimated adiabatic local temperatures well above 1200°C – comparable to decomposition enthalpies of explosives such as nitrocellulose and TNT. As such, it should be possible to both sinter and impart conductivity in one step during the preparation of ceramic paste materials. The project will develop both coatings and composites with adjustable electrical and thermal conductivities. Structure property relationships will be analysed using a range of techniques including photoelectron spectroscopy, mechanical spectroscopy and electron microscopy. The materials robustness to Xray exposure will be tested as a function nanoparticle inclusion. Finally, prototype structures will be fabricated and tested.
The University of Sussex is a leading research-intensive university near Brighton. We have both an international and local outlook, with staff and students from more than 100 countries and frequent engagement in community activities and services.
