The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends: João Maia, Ph.D.
The Role of Interfacial Elasticity on the Rheological Behavior of Polymer Blends
Polymer blends are commonly used to generate materials with a desired combination of performance properties and cost. Most polymer blends are compatibilized to promote stability of the otherwise immiscible components. Compatibilizers also modify the rheology of the blend in complex and important ways. We must integrate extensional rheology, shear rheology, and other techniques to develop a complete understanding of this rich behavior. This webinar will use case studies of two compatibilized blends to elucidate the effect that compatibilizers have on the elasticity of polymer blends and the mechanism behind that behavior.

His main research interests lie in the areas of rheology applied to polymer processing, with an emphasis on the development of new functional multiphase polymeric materials, e.g. blends and composites, on-line sensoring of extrusion and compounding, and extensional rheology.
He has published more than 300 scientific works, including 8 patents, more than 80 papers in international refereed journals, and more than 200 communications to International Conferences, of which more than 20 were Invited/Plenary/keynotes. He was a Fulbright Fellow in 2007 and received the 2010 Annual Award of the British Society of Rheology and the 2011 Morand Lambla Award of the Polymer Processing Society, the latter the highest honor of the PPS. He was the organizer and Co-Chairman of the XVIth International Congress on Rheology held in Lisbon, Portugal in August 2012.
He currently leads five scientific R&D projects and another twelve in cooperation with industry, for a total funding in excess of $5,000,000. His research group is currently constituted by three post-doctoral researchers, fifteen PhD students and several undergraduate students.
