| Annotation | Main idea: Major problem of synthetic polymer nanocomposites is to achieve a good dispersion of nanofiller in polymer matrix. That is why we developed the sandwich method, which is optimized for small samples (10mm x 10mm x 0.5mm) containing homogeneously dispersed nanoparticles. Such specimens are currently used for detailed investigation of nucleation effects and could be also employed in photovoltaic applications. Task: Preparation of sandwich nanocomposites of polypropylene (PP) and various nucleating agents, such as gold nanoparticles (Au-NP) and commercial alpha- and beta-nucleants. The Au-NP will be prepared by both chemical way (synthesis in solution) and physical way (vacuum sputter coater). Characterization of nucleation effects by electron microscopy, differential scanning calorimetry and X-ray diffrection. Originality: Sandwich method is our own, new technique for reproducible preparation of polymer nanocomposites, which will be published soon. By means of this method, we will be able to reliably answer the long-standing question of polymer physics: is the nucleation activity of Au-NP (and also other metallic nanoparticles) influenced by their size, shape and/or chemi |
