Fecha de publicación: | 2022 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Polymers 14 (2022) | Resumen: | A study of different nanocomposites based on poly(ε-caprolactone) (PCL) and mesoporous SBA-15 silica that were prepared by melt extrusion was carried out by analyzing the possible effect of this filler on the crystalline details of PCL, on its mechanical behavior, and on the eventual observation of the confinement of the polymeric chains within the hollow nanometric silica channels. Thus, simultaneous Small-Angle and Wide-Angle X-ray Scattering (SAXS/WAXS) synchrotron experiments at variable temperature were performed on these PCL nanocomposites with different mesoporous silica contents. The importance of the morphological and structural features was assessed by the changes that were observed during the mechanical response of the final materials, which determined that the presence of mesoporous particles leads to a noticeable reinforcing effect. | Versión del editor: | http://dx.doi.org/10.3390/polym14010129 | URI: | http://hdl.handle.net/10261/267455 | DOI: | 10.3390/polym14010129 | Identificadores: | doi: 10.3390/polym14010129 issn: 2073-4360 |
