Biological systems are incredibly efficient at recycling. In fact if we used the world's resources as efficiently as our bodies treat the nutrients in the food we eat, our planet would be in a far better state.
Using nature as an inspiration for next-generation sustainable materials, our researchers are working to create self-regulating, self-repairing systems and to develop new materials that are recyclable or reconfigurable.
As we move into Tranche 2 (2025-2028), we will continue to build on our highly interdisciplinary track-record in soft materials to:
If we used the world’s resources as efficiently as our bodies treat the nutrients in the food we eat, our planet would be in a far better state.
Our vision of how the sustainable materials we use in the future will be underpinned by supramolecular building blocks that assemble and reconfigure on demand.

In this project we will make different kinds of dynamic and stimuli-responsive materials, including emulsions and particles. Progress will continue in controlling the reconfiguration of ‘Pickering’ emulsions (which are dispersions of unmixable liquids stabilised by solid particles) and solid ‘patchy’ particles and hydrogel droplets that reversibly assemble (e.g. into 3D porous matrices) in response to stimulus. We will use these dynamic and stimuli responsive materials in catalysis (using inorganic or organic/biological catalysts) and to control cascade reactions. This includes stimuli responsive giant unilamellar vesicles and coacervates.
Out-of-equilibrium materials will be explored as a subset of dynamic materials, and either higher ordered self-assembled materials or bulk stimuli-responsive materials will also be used to directly influence biological systems, in for example drug delivery or tissue engineering applications. Stimuli responsive materials will also be explored for applications in reservoir computing, in collaboration with the FC programme.

This project will use natural materials directly, after modification or built with principles and inspiration from nature. We will build on our understanding of the piezoelectric properties of protein and peptide assemblies to create energy harvesters and electrically stimulated antimicrobial activity. We will explore application in biomaterials and catalysis (where strain induced electrical charge on the material can influence functional entities, such as nanoparticles or clusters, (tied to CA programme).
Self-assembly of magnetic materials will be explored to create new magnetooptical devices (connected with FC programme). We will build on the understanding of guided assembly of spores to move cargo into hierarchical assemblies, in 2D and 3D. Fungi are known to be able to mediate metal nanoparticle synthesis, so if we link this with controlled assembly, we may be able to create ‘intelligent’ functional assemblies for catalysis or with bespoke magnetic interactions.
This project will also consider material circularity, and will explore functional materials combining sulphides and silicones to create circular materials for commercial applications. Natural materials, especially from waste streams, will also be explored for their use as smart materials (electronics, sensing, antimicrobial, healing) and as starting materials in synthesis of functional materials that can be degraded back into natural components (e.g. fire retardants, sorbents).

Professor Bill Williams of the MacDiarmid Institute and Massey University talks about his job as a scientist and why he loves it.
Working with biophysics and soft materials, Bill describes himself as an experimental scientist who looks at how we perceive the world and works to find ways to test these perceptions. Bill is a scientist because he is fascinated by the world around him and wants to continue to figure out how the world works.
