A coating is a substance applied to a material or a product to enhance the material/product overall properties, such as water wettability, solvent resistance, gas or solvent permeability adhesion, and/or resistance to wear without affecting bulk properties. It can be decorative, protective and – in the case of smart materials – add functionality to the product, i.e. switch properties under external control.
How are coatings used?
Coatings have a broad range of uses, including:
To change the touch/feel of a material
To change gas and solvent permeability of material e.g. to protect gas/moisture sensitive materials
To improve adhesive bonding
To improve wettability and printability of water hating materials
To make ‘splash proof’ or waterproof
To prevent staining of materials
To make self-cleaning
To improve biocompatibility (implants/ex vivo devices)
To impart anti-microbial and anti-viral touch- properties
Functional coatings represent a multi-billion pound industry within the UK and are applied to products as diverse as contact lenses and drinks cartons; they are found in automotive products, textiles, polymer/plastic films, construction materials, and products and processes affected by biofilms, e.g. pipes and medical implants

Undertake proof of concept studies and develop prototypes to demonstrate the feasibility of new and innovative ideas
Trial processes to inform decisions about large-scale production
Within the Department of Physics, the Quantum Technology Centre and clean room offer state-of-the-art facilities for nanoscale device fabrication and characterisation. Our Ultra-Low Temperature labs allow us to cool materials to some of the lowest temperatures ever recorded on Earth. Our recently opened IsoLab is one of the quietest measurement environments in the world.
