The Eurofillers Conference is one of the most important traditional meetings in Europe. It was established in 1995 and, since then, it is organized every two years in a different city of Europe. It aims at bringing together researchers from academia, research organizations and industry in the very important area of filled systems and polymer mixtures. Since 2015, Eurofillers has merged with the Polymer Blends Conference, thus, combining the two topics. It is anticipated that this will lead to a better coordination between the two communities, which will result in more opportunities for collaborative advances to both fields. The Conference will bring together scientists working on polymer blends, interfaces and interphases, polymer composites and nanocomposites, nanostructured polymers, functional materials, bio-based polymers and biocomposites, modern applications of polymers, etc. The scientific program will feature plenary/keynote lectures, invited talks, and oral and poster presentations. The Eurofillers - Polymer Blends 2017 Conference will be held at Hersonissos, Heraklion Crete, Greece during April 23-27, 2017.
