NaPolyNet is a 36 month project involving 15 partners from 10 European countries. The objectives are: 1) to network at regional, national and international level with experts on the characterization of polymer nanostructured materials in the field of packaging, textiles and membranes, bridging the gap between scientific and engineering approaches for the improved understanding of the structure-performance correlation in polymer devices; 2) to facilitate transnational access to important and unique equipment and to train young scientists and SMEs technologists; 3) to harmonize the work necessary for new standards in the field of characterization of polymer nanostructures for packaging, textiles and membranes. NaPolyNet will also focus on latest findings for managing the safety implications of polymer nanostructure along the life-cycle of those products. The activities are grouped into 7 work-packages (WP). After setting up the procedures for managing the project, the team will map the competences in the different field of characterization of polymer nanostructures and will set up an European Open Laboratory (EOL) open to outside the consortium partners incorporating the best and novel characterization methodologies and expertises. The EOL will allow average trained users of equipment for thermal, structural, morphological, mechanical characterization to produce reliable data on nanostructured materials and correctly interpret them. An international Workshop is planned on processing-structure-dynamics-and-properties of polymer nanostructures in order to further support development and design of intrinsically safe nanomaterials. The last part of the project will be dedicated to harmonize the work for preparation of new standards for polymeric nanomaterials characterization and to overcome barriers to the industrial application of polymer nanostructured materials especially in SMEs.
