Polymers and composites

Our polymers and composites researchers focus on developing advanced polymers and multi-functional composites for a variety of applications.

Our research activities and areas of focus include bio-inspired morphing composites, 3D printing polymers, self-healing polymers, stimulus responsive polymers, microgels, hydrogels, and fluorescent gels.

Other activities include preparation of colloidal nanoparticles and nanocomposites via controlled radical dispersion or emulsion polymerisation, perovskite solar cells, characterisation of particles using techniques such as dynamic light scattering, disc centrifuge photosedimentometry, transmission electron microscopy and small-angle X-ray scattering, and investigation into the potential applications of particles (eg for biomineralisation studies or as functional coatings).

We also focus on deposition of conducting polymers onto various templates, synthesis of polymer brushes, peptide materials, preparation of Pickering emulsions and colloidosomes, multifunctional composites for aerospace and biomedical applications, structural health monitoring, and non-destructive techniques.

Case studies

Polymers and composites research is making a significant societal impact, as demonstrated by our case studies:

Peptide hydrogels; from seed funding to commercialisation

Scientists at The University of Manchester have co-founded a new company, Manchester BIOGEL (formerly PeptiGelDesign), based at the BioHub, Alderley Park, which is dedicated to the commercialisation of an innovative hydrogel technology developed at the University.

Work on the peptide-based hydrogels started back in 2004 when Professor Aline Miller (School of Chemical Engineering and Analytical Science) and Professor Alberto Saiani (School of Materials) were awarded a small seed fund of £4,000 from the University. This prompted them to establish, within the University, the Polymers and Peptide Research Group, which is located at the Manchester Institute of Biotechnology. They went on to build on this initial project by attracting over £6 million in funding to the University from public and private bodies over the past ten years. This has led to the development of a technological platform for the design of peptide-based hydrogels, which are now being applied in biomedical and biotechnological fields in areas such as tissue engineering, drug delivery and DNA sensing.

"A true success story"

The technology is based on understanding and controlling the self-assembly of small peptides across the length scales to permit the design of bespoke hydrogel materials. Professor Julie Gough (School of Materials) became involved in the early stage development of these materials for cell culture and tissue engineering applications and she said: "This highly innovative technology actually works. It allows the design of materials that can be tailored to mimic the three-dimensional micro-environment in which we culture cells. Cells have very different requirements depending on their origin, nature and function and this technology allows the design of hydrogels with properties and functionality tailored to each cell type. This opens up new possibilities in cell culture and tissue engineering fields."

Professor Aline Miller, who led the original seed project, said: "This is a true success story. We started over ten years ago with a fundamental science project for which we were awarded a small pot of internal faculty money to do proof-of-concept work and here we are ten years later co-founding a company to sell the novel materials we developed."

In addition to the hydrogel technology, Manchester BIOGEL is also working on bringing to market an innovative cardiac patch medical device that was developed through a collaboration between the University and a number of other European institutions.
