Sažetak
The aim of this work was to produce a new functional filament using glycol-modified polyethylene terephthalate (PET-G) as a polymer matrix with the addition of titanium dioxide (TiO2) and carbon nanotube (CNT) fillers. The composite filament produced is used to manufacture static mixers on the 3D- printer using additive manufacturing technology – fused filament fabrication (FFF). The addition of the fillers modifies the physico- chemical properties of the polymer and gives the polymer photocatalytic properties. TiO2 as a photocatalyst can decompose organic matter under the influence of ultraviolet (UV) light source, such as sunlight for example. CNT is added to the composite to enhance the photocatalytic effect of the TiO2. The addition of the fillers also changes the mechanical properties of the composite compared to PET-G itself. The fillers were added to the polymer matrix in several different ratios. The mechanical properties of the prepared composites were determined. Eight static mixers were successfully manufactured, seven from composite filaments with different filler ratios and one from pure PET-G filament. The manufactured static mixers (Fig. 1.) will later be used to decompose organic pollution in water in the presence of sunlight
