« Nanocomposites from novel polybenzoxazines – Thermal stability, fracture toughness and thermo-mechanical properties »
« Polybenzoxazines have a unique set of thermal, mechanical and chemical properties, which makes them a versatile alternative to several other thermosetting resins. Nevertheless, further improving their thermal stability or thermo-mechanical properties could lead to additional applications. Moreover, benzoxazine share the low toughness characterizing high-performance thermosets. In this work, zinc oxide and carbon-based nanoparticles (CNPs) are used to improve the thermal and thermo-mechanical properties of benzoxazine resins. Next, addition of thermoplastics is shown to effectively activate a large number of toughening mechanisms. Last but not least, we investigate the impact caused by nanoparticles pre-dispersed in these thermoplastics on the mechanisms observed. This masterbatch approach paves the way to one-pot multi-property improvement of polybenzoxazines. »
