We investigate the physics of soft matter systems – materials that include liquid crystals, polymers and biopolymers, glasses, composites, gels and colloids. Our work is primarily experimental; we explore fundamental properties of soft materials and link our discoveries to applications and devices. Recent highlights include: the discovery of a synthetic molecular auxetic material (its thickness increases when strained); producing lightweight, strong, single component composites from sustainable resources; and finding gel solutions for Li+ batteries.
Real-world and scientific impact
As well as publishing our research in top journals, we translate our findings to industry. For example, our cost-effective process for manufacturing lightweight, high-impact resistant polymer composites (Curv®) was commercialised in applications including Samsonite luggage and anti-ballistic body armour. Our research into switchable focus contact lenses led to the formation of the spin-out company, Dynamic Vision Systems Ltd. The group collaborates with Merck chemicals on Non-Display Applications of Liquid Crystals, leading to innovations including polarization-insensitive switchable liquid crystal lenses. We also work iwth DisplayData, QioptiQ and Ultravison on liquid crystals and their applications; Victrex and Propex on polymer composites; QinetiQ and Polystore on polymer gel electrolytes for lithium battery applications; Innovia Films on cellulose processing.
We have superb experimental facilities to evaluate, characterise and test soft materials and devices and a clean-room prototyping laboratory equipped for glass device processing for use with liquid crystal based and other soft-matter devices.
