Thermo-mechanical response of polymer nanocomposites with governed structure

Popis výsledku v původním jazyce

Polymer nanocomposites are promising next-generation materials due to their advanced properties. However, their performance depends strongly on nanoparticle spatial organization in polymer matrix. Self-assembly process was controlled by adjusting preparation protocol conditions on a model system of bare nanosilica and polymethylmethacrylate (PMMA). Three basic dispersion states of nanofiller in polymer matrix were obtained out of different solvents: good dispersion state (steric stabilization), clustered state (bridging/tele-bridging), and aggregated state (contact aggregation). The ability to prepare various nanostructures at constant composition allowed to investigate their influence on final thermomechanical properties. Dependence of glass transition temperature, entanglement network density, and stiffness on structure type was determined.
