7 p, 2.0 MB Replication of nanoscale surface gratings via injection molding / Muntada López, Olga (Institut de Microelectrònica de Barcelona) ; Pina Estany, Jordi (Institut Químic de Sarrià) ; Colominas, Carles (Institut Químic de Sarrià) ; Fraxedas i Calduch, Jordi (Institut Català de Nanociència i Nanotecnologia) ; Pérez Murano, Francesc (Institut de Microelectrònica de Barcelona) ; García Granada, Andrés (Institut Químic de Sarrià)
Nanostructured gratings fabricated on silicon chips have been successfully transferred to polypropylene plastic parts by means of injection molding. Different sets of experiments were carried out along with a repeatability analysis in order to study the effect in the replication of process parameters such as maximum injection pressure, injection time, charge and polymer temperature, geometric factors such as width and separation between lines of the gratings and flow direction as well as demolding conditions.
