Derry MatthewcropResearch

My research career to date has involved the synthesis, characterisation and application of block copolymers. My undergraduate studies included a 12 month industrial placement at Infineum, during which I synthesised polymeric additives for the improved cold flow performance of diesel fuel. My PhD research at the University of Sheffield was conducted in the group of Prof. Steve Armes. This PhD project was fully-funded by Lubrizol and was focused on RAFT-mediated polymerisation-induced self-assembly (PISA) in industrially-relevant non-polar solvents.

PISA Scheme

In addition to the synthesis of diblock copolymer nanoparticles of various morphologies (spheres, worms and vesicles), detailed transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), rheology and shear-induced polarised light imaging (SIPLI) analyses were conducted. In particular, in situ SAXS studies were conducted to provide mechanistic insights into the morphological evolution of diblock copolymer nanoparticles during PISA. After receiving my PhD in 2016, I continued as a postdoctoral researcher in the Armes Group, further researching non-polar PISA formulations.

In Situ SAXS Figure

In April 2017 I began a research project funded by the Leverhulme Trust, which is a joint venture between the Armes and Ryan-Mykhaylyk groups. I am investigating the initial micellisation behaviour of block copolymer assemblies under various conditions using sophisticated small-anglescattering techniques.
