Characterization of hybrid composites reinforced with metal and ceramic nanoparticles

In this study, we prepared a hybrid composite by incorporating metal and ceramic nanoparticles into aliphatic polyketone. Aliphatic polyketone, a copolymer composed of olefin and carbon monoxide has relatively high crystallinity, impact resistance, tribological properties, good resistance to strong acid, and high gas barrier properties. Aluminum and sepiolite powders were compounded with the polymer. The process was carried out using a twin-screw extruder, and dog-bone specimens were prepared via injection molding. The thermal, mechanical, and rheological properties of the composites were analyzed experimentally. In addition, morphological characterization was carried out. When the microflake and nanoparticles were embedded into the composites, the initial pyrolysis temperature were increased. The effect of the nanoparticle addition was more significant than that of the microsized particle addition, and the heat treated sepiolite nanocomposite was found to have the highest viscosity, storage modulus, and loss modulus.

Automated summary

A hybrid composite was prepared by incorporating metal and ceramic nanoparticles into an aliphatic polyketone, which increased the initial pyrolysis temperature and enhanced the mechanical properties. The addition of nanoparticles had a more significant effect on the properties of the composite, and the heat treated sepiolite nanocomposite exhibited the highest viscosity and moduli.
