PhD in Materials Science

The sustainable use of polymeric materials is underpinned by ensuring long service life in all industries and applications. Understanding durability requires research into the effects of both manufacturing methods and environmental storage conditions on the material properties and performance over time. The aim of this project is to understand how the properties of polyolefins (such as polyethylene and polypropylene), affect the gas/vapour transport properties, with a particular focus on the degree of crystallinity and degree of oxidation. The scope of this project would be to design a methodology for capturing material property and gas transport data, gather data on these materials and subsequently build up an understanding of the relationships between the material properties and the solubility and diffusion of gases/vapours. This project will investigate and develop methodologies for understanding the key relationships between fundamental materials properties (degree of crystallinity, extent of oxidation etc), and gas/vapour diffusion and solubility. The transport of water and oxygen are of particular interest due to their presence during manufacture and storage. The effect of exposing a material to either of these species is likely to affect its onward behaviour, and data on these processes will support predictive modelling. The PhD student will be a part of the Surrey/AWE Centre of Excellence in Materials Ageing, Performance and Lifetime Prediction, working closely with our other students, research fellows and industrial sponsors. Your professional and personal development is a priority for us during your doctorate. Funding is also available for training events and international conference attendance is encouraged. This is in addition to support from the University’s Doctoral College and our annual Centre of Excellence conference.
