Current interests

Martin Rides

Dr Martin Rides is currently involved in the development of techniques for the measurement of the rheological and thermal properties of polymeric systems, with particular interests in developing reduced length-scale measurement capability. Applications are, for example, for characterisation of pharmaceuticals facilitating drug development, and for thermal analysis of polymeric micro-mouldings and devices to facilitate design and product enhance performance.


Martin has in excess of 25 years experience in research in the development of test methods for polymeric materials. He graduated with a PhD from Brunel University in 1993, where his thesis was on the measurement and modelling of the flow properties of thermosetting materials. His expertise is in the characterisation of the rheological (flow) properties of polymeric materials. The techniques covered have included melt flow rate testing of thermoplastics to the more elaborate measurement of the extensional viscoelastic behaviour of polymers. More recently, he has worked on development of test methods for thermophysical properties characterisation of materials, including the use of AFM-based thermally active devices. Increasing emphasis has been on applications in the pharmaceutical and medical devices sectors.

Martin is actively involved in the development of ISO standards for rheological properties of polymers. He is currently the chairman of the ISO Working Group on Melt Rheology of Plastics (ISO TC61/SC5/WG9), and UK delegate for the Working Groups on Thermal Properties (ISO TC61/SC5/WG8) and Viscosity (ISO TC61/SC5/WG5). He is a member of the Institute of Materials, Minerals and Mining and of the British Society of Rheology. He is also a committee member of the Polymer Society Board of the Institute of Materials, Minerals and Mining, representing and promoting the interests of the polymers and rubber community within and by the Institute.

Martin leads the Polymeric Materials research at NPL. He has been and continues to be involved in developing and executing collaborative research projects, including Technology Strategy Board and European Framework funded activity, and corporate funded research. He has published over 100 reports and papers, and has led the development of several, now published, ISO standards.
