The Centre for Sustainable & Circular Technologies (CSCT) at the University of Bath is inviting applications for the following PhD project which is part of a joint PhD programme between the University of Bath and Monash University in Australia.
This project is one of a number that are in competition for up to three funded studentships.
Home institution: University of Bath
Supervisor(s) at Bath: Dr Antoine Buchard, Dr Hannah Leese
Supervisor(s) at Monash: Prof Tanja Junkers
The reliance of plastic materials on fossil resources and concerns about their end of life necessitate a transition to a circular economy of plastics. One vision for sustainable plastics is that of a class of materials, derived from renewable feedstocks, which exhibit closed-loop life cycles (mechanical and chemical recyclability and/or biodegradability). However, a major technological barrier limiting the widespread adoption of polymers from renewable feedstocks is the need to achieve a delicate balance between thermomechanical performance and degradability.
One strategy used to tune the properties of polymeric materials is the copolymerisation between two or more monomers, combined with the control of the composition and sequence of the resulting copolymers. This usually necessitates the determination of monomers relative reactivity ratios, which is a lengthy and labour-intensive process. In addition, the differences in intrinsic reactivities of monomers means that it can be extremely challenging to achieve specific sequences, in particular statistical copolymers. Unfortunately, these challenges considerably limit our ability to discover new materials that could address technological needs (e.g., materials with high gas barrier properties but with embedded or triggerable degradability).
In particular, at Bath, the Buchard group (www.buchargroup.org) has been developing a platform of monomers and polymers derived from sugars.[1-3] These renewable and degradable materials have shown promise for a variety of applications, including packaging, battery solid electrolytes and health materials (in collaboration with the Leese group (www.materialsforhealthlab.org). Considering the diversity of sugar feedstocks, and the possibilities offered by copolymerisation, the structure/property space to explore is immense and necessitates a rational and optimised approach.
In Monash, the Junkers group (www.polymatter.net) specialises in the precise engineering of polymers using flow processes and on-line analysis of polymerisation reactions. Recently, they have for example developed a continuous flow system for automated high-throughput screening and autonomous optimisation of radical polymerisations, which is controlled by a machine-learning algorithm that continuously vary reaction parameters until target molecular weights are achieved.[4-5]
In this collaborative and multidisciplinary project, we will develop an experimental set-up which is able to vary copolymerisation reaction parameters (rate of addition, concentrations, temperature etc.) and automatically explore new bio-derived copolymer compositions and sequences, and relate those to the polymer physical properties, which will ultimately inform the design of materials with enhanced characteristics.

Studentship eligibility
Funding for Bath-based projects, such as the one advertised here, is available to candidates who qualify for Home fee status only. In determining Home student status, we follow the UK government’s fee regulations and guidance from the UK Council for International Student Affairs (UKCISA). Further information may also be found within the university’s fee status guidance.
EU/EEA citizens who live outside the UK are unlikely to be eligible for Home fees and funding.
Funding for Monash-based projects is available to candidates of any nationality.
Please see the CSCT website for a full list of available projects.
