Francis Clegg graduated from Sheffield Hallam University in 1994 with a degree in Applied Chemistry and continued at the same establishment within MERI to complete a PhD in 1998 involving the physicochemical properties of organo-mineral interactions.
After one year in the Chemical and Process Engineering Department at the University of Newcastle, Francis returned to MERI in 1999 to further his research in organo-mineral interactions with particular emphasis on polymer (nano)composites.
As a Senior Research Fellow and chemist at heart, Francis's current research interests are fulfilled within several polymer and composite projects, including:
• Sustainable and flexible high barrier packaging;
• Controlled release open wound dressings;
• Fire retardant composite resins;
• Polymer membranes and surface modification;
• Stimuli responsive shape memory polymers;
• Intumescent paints.
At the core of these projects is a detailed understanding of the interaction and compatibility of composite fillers with the polymer matrix. This is particularly relevant to the organo-mineral interactions involved in clay-polymer nanocomposites. Complimentary knowledge and practical application of the extensive analytical instruments within MERI (in particularly thermo-analytical) allows an enhanced understanding of the systems and allows further development of the research and novel products.
In addition to being involved in internal, UK government and European Funded projects, Francis actively engages in consultancy and has worked successfully with companies both small and large, national and international.
To help deliver on research projects Francis supervises and works alongside Erasmus and visiting PhD research students to offer working experience via a hands on approach.
