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.
