Phthalocyanines are important in coating technology primarily as stable, vibrant pigments that improve the aesthetic, durability, and sometimes functional performance of coatings in industrial, automotive, architectural, and specialty applications. Based on this purpose, in this work we used cobalt phthalocyanine complex for surface coating with antibacterial properties. For this purpose, cobalt (II) phthalocyanine (Pc) was coated onto titanium (cp-Ti) by dip coating process. The phase compositions, morphology and elemental distribution amount of the surfaces were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDX-mapping and EDX-area), respectively. Wettability and surface free energy of the surfaces were investigated by sessile drop - contact angle goniometer. Pc-coated surface indicated more hydrophobic behavior compared to bare Ti surface. Moreover, in vitro antibacterial activity of all surfaces evaluated under dark- and sunlight-conditions by bacterial count method via Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). For both bacteria, it was demonstrated that the antibacterial activity was in excess of 92 % under sunlight conditions while it was less than 8 % under dark conditions.
