Welcome to the fascinating world of molecules and macromolecules.

We carry out fundamental research on polymers and their interactions with small molecules. We seek to apply our knowledge for the benefit of society and are developing novel materials for a variety of industrial and medical applications.


Polymers of intrinsic microporosity (PIMs) were invented in Manchester. They behave like moelcular sieves because they have rigid, contorted macromolecular backbones.


A membrane may be used to separate mixtures of gases or liquids into their components. To be useful, a membrane material needs to be both highly selective (i.e., one type of molecule must pass through more easily than others) and highly permeable (i.e., it must let a lot through). We are developing membranes for applications such as carbon dioxide capture and biofuel recovery.


In collaboration with researchers across the Faculty of Science and Engineering, we are seeking to develop the science and technology of graphene-based membranes, exploring a range of applications in molecular separations, as barrier materials, in fuel cells, and in sensors. Watch a video about graphene-based membranes.


Polyelectrolytes are polymers that possess many ionizable groups. We are investigating bioactive polyelectrolytes for tissue engineering and other applications.


When postdoctoral research associate postions or funded PhD studentships are available, they are advertised on the University website. We regret that we cannot respond to speculative enquiries, due to the large number that are received.


Africa link

A collaboration with Kwame Nkrumah University of Science and Technology, Ghana, has led to a paper in the European Journal of Lipid Science and Technology, about potentially useful oils from African plants.

PhD success

Congratulations to Lei Gao (Jonathan) on achieving his PhD. You can read about some of his resarch in the Journal of Membrane Science.

Helping bone grow

Two papers in the Journal of Biomedical Materials Research: Part A show the potential of poly(vinyl phosphonic acid-co-acrylic acid) in bone regeneration. One discusses the ability of the polymer to bind calcium and its effects on osteogenesis, the other demonstrates that hydrogels of the polymer can promote osteoblast adhesion and proliferation.

Book chapter

The 2nd edition of Comprehensive Membrane Science and Engineering includes a chapter on "Membranes Made of Polymers of Intrinsic Microporosity (PIMs)" by Sara Sorribas, Marzieh Tamaddondar and Peter Budd.

Membranes in San Francisco

Peter Budd and Andrew Foster were in San Francisco for the International Congress on Membranes and Membrane Processes (ICOM), 29 July - 4 August 2017. The next ICOM will be in London in 2020.

Materials Chemists in Liverpool

Peter Budd gave a talk and Tom Raine presented a poster at the International Conference on Materials Chemistry (MC13) in Liverpool, 10-13 July 2017.

Membranes in MOOCs

Our research features in massive online open courses (MOOCs) on "Graphene and 2D Materials" and "Industrial Biotechnology."

Graphene membranes video

A video about graphene-based membranes has been viewed over 93,000 times. You can see it on YouTube or on the graphene website.

Speaking in Schools

An academic guest lecture on "Giant Molecules and 2D Materials" teaches young people about our research. We have visited Audenshaw School, Buxton Cummunity School, Al-Jimiatul Islamiyah School in Bolton, Giggleswick School and South Wirral High School.

SynFabFun in the Peak

Members of the SynFabFun consortium gathered for a workshop in March 2017 at Shrigley Hall, on the edge of the Peak District. The SynFabFun Programme Grant brings together researchers from Manchester, Newcastle, Edinburgh, Bath and Imperial College, working on membrane synthesis, fabrication and application.

Membranes in Saudi Arabia

Peter Budd spoke at a research conference of the Advanced Membranes and Porous Materials Center at the King Abdullah University of Science and Technology (KAUST), 20-23 Feb. 2017.


A paper in the Journal of Membrane Science reports nanocomposite membranes of the polymer PIM-1 with polyhedral oligomeric phenethyl-silsesquioxanes (POSS)

Pulling an alcohol out of water

Two papers in the Journal of Membrane Science describe research on membranes for the energy-efficient recovery of biobutanol. One shows that the addition of graphene-like fillers to a polymer of intrinsic microporosity (PIM) can enhance the separation. The other shows that thin films of a PIM in a composite structure can give membranes with high productivity.

Separating colours

A paper in the Journal of Colloid and Interface Science shows how a polymer of intrinsic microporosity (PIM) can be modified in different ways, in order to isolate different types of dye.

Constrained polymer

A Scientific Report shows how selective transport of gases and vapours is changed when a polymer of intrinsic microporosity (PIM) is constrained in nanoscale channels.

Award for product utilising Manchester invention

The 3M Organic Vapour Filter End of Service Life Indicator won a Product Innovation Award from the British Safety Industry Federation. The product uses a Polymer of Intrinsic Microporosity invented in Manchester. You can read about the product in the May 2015 issue of "Tomorrow's Health & Safety", on p. 36. More information.
