Surface characteristics of metal-like composites fabricated with aliphatic polyketone

Recently, consumers have shown a growing interest in polymeric products that offer high aesthetic and comfort features, along with superior engineering performance. In response to this demand, we conducted a study on metallic polymer composites, utilizing metal fillers and polymers. To create these composites, micro-sized aluminum flakes and nano-sized spherical aluminum powder were combined with aliphatic polyketone. Furthermore, an ion-beam irradiation process was employed to enhance the surface properties of the products, including surface hardness, modulus, and glossiness. The compounding process was carried out using a twin-screw extruder, and disk-shaped specimens were prepared through injection molding. Subsequently, nitrogen ion-beam irradiation was applied to the prepared specimens. Comprehensive analysis was performed to evaluate the mechanical, aesthetic, structural, and morphological properties of these metal-like composites.
