Processing and integration of nanoscale materials into functional devices

The research into materials with nanoscale structure is led by Dr Izabela Jurewicz.

International journals

Our work on nanocomposites of polymer colloids and carbon nanotubes (CNTs) has appeared on the front cover of two international journals.

Self-assembly of nanomaterials into ordered arrays

We developed a novel preparation method which enables the organization of carbon nanotubes, graphene and related 2D materials into extended 3D honeycomb-like networks. It allows the precise control of the electrical percolation threshold – a major prerequisite to developing new transparent conducting films, conducting paints and coatings and photonics.

Carbon nanotube based textiles for applications ranging from energy storage to tissue engineering

This project funded by EPSRC (click here) is focused on advancing the science and technology for multifunctional carbon nanotube (CNT) textiles for energy storage applications. Particular focus is placed on the optimization of the cathode structure of batteries and the development of all-textile flexible electrochemical double layer supercapacitor.

Our research focuses on the development of 2D and 3D textiles based on carbon nanotube (CNT) fibers and yarns made by a wet-spinning process and a dry-spinning process respectively.

Fibers are then plied, twisted and textured to form several geometries with a wide range of mechanical outcomes. Twisting fibers into yarns and then knitting or weaving the yarns into a fabric facilitates the formation of 2D and 3D well defined porous structures with versatile porosity and ultra-high specific surface area providing a highly conductive, low density scaffold for energy storage.

Our work also focuses on the development of synthetic scaffolds for tissue engineering. Our functional thin films and textiles based on carbon nanotubes, graphene and nanomaterial/peptide hybrid structures are perfect candidates for culturing cells in the 2D and 3D environment. We work together with colleagues in the University's School of Veterinary Medicine, to apply these textiles for uses for animal health.
